What are the types of ASP.NET projects?

You can create different types of ASP.net projects in Visual Studio 2010 , they are :

1. Web Sites 
2. Web Applications
3. Web Services
4. AJAX  Server

What is Visual Web Developer and its Features?

Visual Web Developer is a full-featured development environment for creating ASP.NET Web applications

It offers the following features:

•  Web Page Design
•  Page Design Features
•  Code Editing
•  Testing and Debugging (A local Web Server for testing and a debugger that helps you find errors in programs)
•  Deployment (Tools to automate typical task for deploying a Web applications to a hosting server or a hosting provider)

 

Testing and Debugging

•  Visual Web Developer provides an ideal environment in which to build Web sites and the npublish them to a hosting site.
•  Visual Web Developer includes a local Web server that provides all the features you need to test and debug ASP.NET Web pages,without requiring IIS to be installed
•  Finally, you can take the advantage of the built-in suppoert for the File Transfer Protocol(FTP), using the Visual Web Developer , you can connect directly to the host computer and then create and edit files on the server

Introduction to ASP.NET 4.0

• ASP.NET is a Web Platform that provides all the services that we require to build server-based Web applications.
• ASP.NET is built upon .NET Framework, so all .NET features are available to ASP.NET applications.
• ASP.NET applications can be written in any language that is compatible with the CLR , including Visual Basic and C#

• To create ASP.NET Web applications , we can use Visual Studio.
• The tools and options in Visual Studio that are designed for creating Web Applications are referred to as 'Visual Web Developer'.

SharePoint 2010 Security model

• Understanding SharePoint security model requires understanding the difference between 'Authentication process and Authorization process'
• Authentication is the mechanism by which systems securely identify the user attempting to access a resource 
• Authorization is the mechanism by which a system determines the level of access the authenticated user 

• SharePoint itself does not perform any authentication.
• The authentication process is handled by an underlying authentication system, For example windows authentication is handled by Windows Server and IIS.
• SharePoint only performs authorization to secured sources contained in sites,lists,libraries...
• SharePoint 2010 offers two different authentication mode : Classic authentication mode and Claims-based authentication mode

  Classic mode Authentication:

•  It refers to the integrated windows authentication
•  You cannot configure the form based application if your web application is using Classic mode authentication 
•  You can convert a web application from Classic mode authentication to Claims-based by only using  Powershell Command and it an irreversible process

Claims-based Authentication:

•  SharePoint 2010 is built upon Windows Identity Foundation 
•  It enables authentication from as well as non-windows based system.
•  This also provides the capability to have multiple authentication in a single URL
•  Claim-based authentication is built upon Windows Identity Framework

How to give user permission for a web application

It is easy to add a user to a site collection of a web application, but what if we want to add a user to 100s of site collection of a we application?, in such cases we give the control to Central administrator who can do these steps:

Step1 : Go to Central administration
Step2 : Go to Application Management
Step3 : Go to Mange Web application
Step4: Select the Web application from the list
Step5: Click 'User Policy' shown on the ribbon
Step6: Do 'Add User' -> select user zone Click Finish

Resource Throttling in SharePoint 2010 Server

Throttle means setting up limit.
Throttling provides the option of monitoring and throttling the server resource and large list for web applications.
This enables you to control resource utilization during the peak usage and prevent user from negativity effecting the server performance

Resource throttling can monitor resources like CPU,Memory.
During the period of active throttling HTTP GET request and search robots will generate a 503 error

Why do we need LINQ?

LINQ: Language Integrated Query.

Queries are the one which retrieve data from a data source, SQL can be a data source or XML can be another data source.
SQL is the query type used to retrieve database data type from a database source.
Xquery is another type to retrieve xml data from xml data source.

So we developers have to learn different query types for each data formats,LINQ simplifies this situation by offering a consistent model for working with data across various kind of data format and data source.

In LINQ query you will be always working with 'Objects'. You use the same basic coding pattern to query data from XML,SQL,ADO.net ,.net collections etc..

SharePoint 2010 UI enhancements

SharePoint 2010 shipped with lot of UI enhancement they are:

• Ribbon Toolbar

           Now SP 2010 has UI as like in other Microsoft products, with ribbon interface it is easy to work in SharePoint sites,document library,lists,calendar,and other items

• AJAX enabled

          Most of the activities in SP 2010 are AJAX enabled, Inserting /Editing or deleting items in List or Document library actions are available in place and require no full page request.

• Bread Crumbs

      Shows links in tree view structure and makes navigation much easier.

• Developer dashboard

      Developer dashboard is for the developers to diagnose  and monitor page, it displays various database calls, webpart execution time, authenticates user, critical errors and various SP request object calls.

• Pop-up dialog boxes

       In SharePoint 2007 whenever you do any activity like creating new list etc. it directs to new windows and we have to come back to the main list after its completion, to overcome page traversals , SP 2010 pops up a dialog instead of redirecting to new page

.Net Interoperability

• .Net framework supports interoperability.
• Interoperability is the ability of two systems to communicate with each other, The first system could be built on .Net framework and the other system can be of some other technology.

.Net Interoperability is of two types:

•  Managed code interoperability
•  Unmanaged code interoperability

Manged code interoperability:
 Create a class library in c sharp, which has a method called Hello()

 Call the c sharp class library in VB project.

Difference between Array and Array List

• An array can contain only one data type, while array list can contain any data type in the form of object.
• With array you cannot dynamically increase or decrease the size of the array, but array list automatically increases the size, when any element or object is added.

When to use Interface and Abstract Class

• Interface members cannot have a definition
• All interface members should be implemented by the derived class
• An abstract class can have an instance field in it. The derived classes can assess this field through the  base syntax. This is the key difference between abstract and interfaces.

Abstract class can contain non abstract method. When we want that all subclass must implement all methods of base class ;In such situation use interface.In other hand when we want only some method of base class in our subclass then use base class as abstract class because abstract class can contain non-abstract method. Interfaces are used when we want classes should follow the rules strictly. Rules like naming coventions e.g. if in customer class one developer add method AddCustomer other developer while implementing Invoice class could write method name InvoiceAdd and also could change the Signiture rules. for addition of customer we have at client code as Cutomer.AddCustomer(A,B,C); and Invoice.InvoiceAdd(A,B) To maintain uniformality if we declare interface and define method Add(A,B) in that interface and implement that interface in both the classes then the code will be uniform all over the classes where ever we have implemented interface and also all concrete classes must contain methods which are defined in the interfaces. Interface: –> If your child classes should all implement a certain group of methods/functionalities but each of the child classes is free to provide its own implementation then use interfaces. For e.g. if you are implementing a class hierarchy for vehicles implement an interface called Vehicle which has properties like Colour MaxSpeed etc. and methods like Drive(). All child classes like Car Scooter AirPlane SolarCar etc. should derive from this base interface but provide a seperate implementation of the methods and properties exposed by Vehicle. –> If you want your child classes to implement multiple unrelated functionalities in short multiple inheritance use interfaces. For e.g. if you are implementing a class called SpaceShip that has to have functionalities from a Vehicle as well as that from a UFO then make both Vehicle and UFO as interfaces and then create a class SpaceShip that implements both Vehicle and UFO . Abstract Classes –> When you have a requirement where your base class should provide default implementation of certain methods whereas other methods should be open to being overridden by child classes use abstract classes. For e.g. again take the example of the Vehicle class above. If we want all classes deriving from Vehicle to implement the Drive() method in a fixed way whereas the other methods can be overridden by child classes. In such a scenario we implement the Vehicle class as an abstract class with an implementation of Drive while leave the other methods / properties as abstract so they could be overridden by child classes. –> The purpose of an abstract class is to provide a common definition of a base class that multiple derived classes can share. For example a class library may define an abstract class that is used as a parameter to many of its functions and require programmers using that library to provide their own implementation of the class by creating a derived class. Use an abstract class * When creating a class library which will be widely distributed or reused—especially to clients, use an abstract class in preference to an interface; because, it simplifies versioning. This is the practice used by the Microsoft team which developed the Base Class Library. ( COM was designed around interfaces.) * Use an abstract class to define a common base class for a family of types. * Use an abstract class to provide default behavior. * Subclass only a base class in a hierarchy to which the class logically belongs. Use an interface * When creating a standalone project which can be changed at will, use an interface in preference to an abstract class; because, it offers more design flexibility. * Use interfaces to introduce polymorphic behavior without subclassing and to model multiple inheritance—allowing a specific type to support numerous behaviors. * Use an interface to design a polymorphic hierarchy for value types. * Use an interface when an immutable contract is really intended. * A well-designed interface defines a very specific range of functionality. Split up interfaces that contain unrelated functionality.

When to use Interface

If the requirement is like that something in your design changes frequently then go for interfaces instead of classes .

C# doesn't support Multiple Inheritance

but it supports Multi-level inhertance

C# Constants

• Constants are immutable values which are known at the compile time.


• They do not change for the life of the program


• C# built in types may be declared as constants


• User-defined types including Classes, structs , arrays cannot be 'const'


• C # does not support const methods,properties or events


• When a complier encounters a const identifier in c# source code, it substitutes the literal value into the intermediate language(IL) code the produces 


• Because there is no variable address associated with a constant at run time.


• Constant fields cannot be passed by reference 


• Constants are marked by public,private,protected,internal.

Why to use DLL

A DLL is a collection of small programs, which can be called when needed by a larger program that is running in the computer. The small program that lets the larger communicate with a specific device such as printer or scanner is often packged as a a DLL program.

The advantages of DLL:
DLL's don't get loaded in RAM together with the program , so space is saved in RAM(Random Access Memory).

When and if a DLL file is needed, then it is loaded and run. For example, as long as a user of Microsoft Word is editing a document, the printer DLL file does not need to be loaded into RAM. If the user decides to print the document, then the Word application causes the printer DLL file to be loaded and run.

Why do we need Try-Finally block

The output that the code in the finally block will be executed after throwing the exception. However, the last statements in the program that followed the finally block will not be executed. This means that the exception
prevents control from being transferred to any part of the program except the finally block.

using System;

public class MyClass

{

static void Main()

{

string myString = "Finally";

object myObject = myString;

try

{

// The following conversion is invalid.

// It throws an exception.

int myInt = (int)myObject;

}

finally

{

// The code in this block is always executed:

Console.WriteLine("The program continues and ends here:");

Console.WriteLine("My String is: {0}", myString);

}

// The following code will not be executed:

Console.WriteLine("Hello again!");

}

}

It is also used for cleaning up the resource, like to close the open file stream..

Through PowerShell Scripting you will be able to start, stop, and change status types of a service on multiple computers without much effort. Write a script, run-it, and then kick you feet up on the desk.

Sharepoint 2010 Client Object Model

1. Why do we need Client Object Model ? /  Why Client Object Model evolved ?
    
        Microsoft was constantly getting request from customers for more webservices. to make it easier to get data from outside of sharepoint (for example : to show sharepoint data on your desktop, by consuming a webservices), So there are two options: 1) Request microsoft to produce more web serivices or 2) Create your own custom web services, Instead creating more and more web services over and over agin in each release,  Microsoft  came up with a different approach , they created someting called 'Client Object Model'.
 
2.Client Object Model comes in three flavours:

a. .NET web services
b. ECMAScript(javascript)
c. Silverlight

      

3.Where SP Client Object Model can be used to get data :

 a.Site Collections and Sites
 b.Lists,List Items,Views, and List Schemas
 c.Files and Folders
 d.Web,List, and List Item Propert bags
 e.Web parts
 f. Security
 g.Content Types
 h.Site Templates and Site Collection Operation


SharePoint 2010 allows using its Object model to run against a server running SharePoint. For clients (not running SharePoint in the box), the simplest way to communicate with SharePoint server is web services. SharePoint Client Object Model (OM) can be run on client PC (where SharePoint is not installed) to communicate with SharePoint server. So whereas SharePoint (Server) Object Model runs in a SharePoint server and can manipulate SharePoint objects, client OM can run in client PC and communicate with SharePoint server remotely.

Sharepoint 2010 Workflows

1.What is a WorkFlow?

•   Workflow is a series of action that corresponds to a work process, such as creating remedy request, making purchase orders.
•   Sharepoint 2010 helps to automate these workflows , thereby increasing the productivity and efficiency of the organization.

2.What are the type of workflows that can be designed in SP 2010?

•  List workflows
•  Reusable List workflows
•  Site Workflows

3.What are Reusable List workflows and Site Workflow?

   Resuable Workflows: We can create reusable list workflow in the top-level site in  the site collection and that workflow can be made globally reusable - meaning the workflow can be associated to any list, library or content type in the site collection. We can create reusable workflow in any subsite in the site collection and this workflow will be available for reuse in that particular subsite.

Site Workflow: Site workflow is associated to a site - not to a list/library/content type

Sharepoint 2010 recycle bin

Recycle bin allows users to restore the objects that are deleted.Microsoft sharpoint server 2010 supports two stages of recycle bin:
a.The first stage recycle bin 
b.Site collection - the second stage .

When recycle bins are enabled then users can restore items,documents etc.

When a user does this	The item is	The item can be restored by
Deletes an item	Held in the first-stage Recycle Bin until the item is deleted from the Recycle Bin or the item has been in the Recycle Bin longer than the time limit configured for an item to be held in the Recycle Bin.	Users or site collection administrators
Deletes an item from the Recycle   Bin	Held in the second-stage Recycle Bin	Site collection administrators

First Stage Recycle bin: The first stage recycle bin is located at site level and it is available to users who have Contribute, Design or Full Control permission on a site.When a user deletes an item from a Web site, the item is sent to the site's first-stage Recycle Bin. Items located in the first-stage Recycle Bin count toward the site quota.Items remain in one of the first-stage Recycle Bins in the site until a specified time period has been reached (the default setting is 30 days).

Second Stage Recycle Bin: The second stage site collection is located at site collection administrator level.
Items remain in the second-stage Recycle Bin until a specified time period has been reached (the default setting is 30 days) or until the second-stage Recycle Bin reaches its size limit, at which time the oldest items are deleted. The time limit for the Recycle Bins applies to the total time after the item was initially deleted — not the time spent in either Recycle Bin stage.

SharePoint 2010 developer dashboard

The developer dashboard is an instrumentation framework.Developer Dahsboard contains an extensible mechanism for measuring various performance counters at various scopes.

The developer dashboard records and displays the performance statistics of the code that executed to produce the current page .

Developer Dashboard contains an extensible mechanism for measuring various performance counters at various scopes. Within Developer Dashboard, the following performance counters are used to monitor usage and resource consumption at each stage of the requests.

Per-threaded Counters:

These counters measure values for the current request or timer job:

• Thread execution time
• Number, duration, call stack information and query text of each SQL Server query generated by the page
• Number, duration, and call stack information of each WCF call
• URL or timer job name
• Current user
• Execution start time

The Developer Dashboard can be displayed in the following modes:

• On
  When enabled in On mode, the Dashboard is viewable on all pages that use the default master page.
• OnDemand
  When the Developer Dashboard is set to OnDemand mode, an icon is displayed on the top right side of the page. This icon allows the user to toggle the Dashboard on and off.

Run this command in powershell:

PS C:\Users\Administrator > stsadm -o setproperty -pn developer-dashboard -pv on

What is C Sharp Using statement

The Using statement in C# allows you to define the scope of an object lifetime, when the end of the using satament is reached  the object Dispose() will be called immediatly.

using (SqlConnection conn = new SqlConnection(connString))
{
     SqlCommand cmd = conn.CreateCommand();
     cmd.CommandText = "SELECT * FROM Customers";
     conn.Open();
     using (SqlDataReader dr = cmd.ExecuteReader()) {
          while (dr.Read())
          // Do Something...
     }
}

This is extremly useful when we need to release a resourece intensive object, like database connection object or a transaction scope

Sharepoint 2010 Connectable webparts

 This post describes how to create connectable webparts in Sharepoint 2010

A webpart that provides a string and another webpart that consumes and displays the value of the string.
These are the tasks to be followed :

1. Creating an interface to define the string that is being provided.
2. Creating a webpart from Visual Studio Webpart item template
3. Creating a provider webpart that defines a string
4. Creating a consumer webpart that uses and displays a string
5. Creating a webpart page and connecting the provider and consumer webpart.


A)  Creating an empty sharepoint project :

1. Start Visual Studio 2010 in administrator mode.
2. On the File menu, point to New, and then click Project. If Visual Studio is set to use Visual Basic development settings, on the File menu, click New Project.
3. In the New Project dialog box, expand the SharePoint node under the language that you want to use, and then select the 2010 node.
4. In the Templates pane, select Empty SharePoint Project.
5. For the name of the project, type ConnectableWebParts, and then click OK.
6. In the What local site do you want to use for debugging? drop-down list, select the local site that you want to use for debugging.
7. Select Deploy as a farm solution, and then click Finish

 B) Creating an Interface : (what is an Interface?)

   

          public interface ITextBoxString

          {

             string TextBoxString { get; set;}

          }  

C) Creating a Provider Webpart

1. In Solution Explorer, click the ConnectableWebParts project.
2. On the Project menu, click Add New Item.
3. In the Installed Templates pane, expand the SharePoint node, and then click 2010.
4. Click Web Part, type StringProvider for the name of the Web Part, and then click Add.
5. In the StringProvider.cs or StringProvider.vb code file, add the following code to indicate that the StringProvider class implements the ITextBoxString interface.

  public class StringProvider :Webpart, ITextBoxString
  
   6. Add the following code to create a text box, string and a button
 
     private TextBox myTextBox;
     private String _textBoxString = String.Empty;
     private Button myButton;

   7.  Implement the get and set method of the ItextBoxstring interface by adding the following code:
  

 
  [Personalizable()]
public string TextBoxString
{ get
    {
        return _textBoxString;
    }
    set
    {
        _textBoxString = value;
    }
}

                                               (what is personlisation)

  8. CreateChildControls(): instantiates controls and adds new control to the webpart
   
protected override void CreateChildControls()
{
    Controls.Clear();
    myTextBox = new TextBox();
    Controls.Add(myTextBox);

    myButton = new Button();
    myButton.Text = "Change Text";
    Controls.Add(myButton);
    myButton.Click += new EventHandler(myButton_Click);
}

9. Code to handel Click event

protected override void CreateChildControls()
{
    Controls.Clear();
    myTextBox = new TextBox();
    Controls.Add(myTextBox);

    myButton = new Button();
    myButton.Text = "Change Text";
    Controls.Add(myButton);
    myButton.Click += new EventHandler(myButton_Click);
}
10. Create a method to return tothe ITextBoxString object to share to other webpart.  Apply the ConnectionProviderAttribute attribute to identify the callback method that acts as the provider in a Web Parts connection.


[ConnectionProvider("Provider for String From TextBox", "TextBoxStringProvider")]
public ITextBoxString TextBoxStringProvider()
{
    return this;
}


D) Creating a Consumer Webpart

1. In Solution Explorer, click the ConnectableWebParts project.
2. On the Project menu, click Add New Item.
3. In the Installed Templates pane, expand the SharePoint node, and then click 2010.
4. Click Web Part, type StringConsumer for the name of the interface, and then click Add.
5. In the StringConsumer.cs or StringConsumer.vb code file, add the following code to create objects for an ITextBoxString provider and a text box.

private ITextBoxString _myProvider;
private Label myLabel;

protected override void OnPreRender(EventArgs e)
{
    EnsureChildControls();
    if (_myProvider != null)
    {
        myLabel.Text = _myProvider.TextBoxString;
    }
}

protected override void CreateChildControls()
{
    Controls.Clear();
    myLabel = new Label();
    myLabel.Text = "Default text";
    Controls.Add(myLabel);
}

 [ConnectionConsumer("String Consumer", "StringConsumer")]
public void TextBoxStringConsumer(ITextBoxString Provider)
{
    _myProvider = Provider;
} 

E) Connecting the Provider and Consumer Webpart

1. In Solution Explorer, click the ConnectableWebParts project.
2. On the Project menu, click Add New Item.
3. In the Installed Templates pane, click Code.
4. Click Interface.
5. Type ITextBoxString for the name of the interface, and then click Add.
6. In the ITextBoxString.cs or ITextBoxString.vb code file, mark or verify that the ITextBoxString class is public
