What is Authentication and Authorization?

In simple words Authentication is the process that addresses the question “Who are you?“. Authentication is done by obtaining a valid username and password on an internet or intranet system. Once a user is authenticated, the system confirms that you match with the identity who you claim to be. However, authentication doesn’t confirm whether you are authorized to access the resource that you might be trying to access; that is done by Authorization.
Authorization addresses the question “What Can You Do?” and this happens after successful authentication. Authorization is the process of verifying that a user is allowed to access a requested resource. Read Full Article Here

Using ADO .NET Entity Framework 5.0

November 16th, 2013 | Posted by Vidya Vrat in .NET | C# | Entity Framework - (0 Comments)

With the release of .NET Framework 4.5 and Visual Studio 2012, a new version of ADO.NET Entity Framework 5.0 was introduced. This article will introduce you to the ADO.NET Entity Framework 5.0 data model, also known as the Entity Data Model (EDM).

EDM is Microsoft’s way of implementing object-relational mapping (ORM). ORM is a way of processing and mapping relational data into a collection of objects, called entities. You will learn more about it, including the advantages of this approach, in this article.

In this article, I’ll cover the following:
•Understanding ADO.NET Entity Framework 5.0
•Understanding the Entity Data Model
•Working with the Entity Data Model

LINQ introduces a standard, unified, easy-to-learn approach for querying and modifying data, and can be extended to support potentially any type of data store. Visual Studio 2012 also supports LINQ provider assemblies that enable the use of LINQ queries with various types of data sources including relational data, XML, and in-memory data structures.

Asynchronous Programming with C# 5.0

August 12th, 2013 | Posted by Vidya Vrat in .NET | C# - (0 Comments)

Because a synchronous method call can create a delay in program flow which turns out to be bad user experience. Hence, an asynchronous approach will be better. Asynchronous method call will return immediately so that the program can perform other operations while the called method completes its work in certain situations.

The asynchronous methods behavior is different than synchronous ones. You call them; they start executing, but return the control back to the thread which called them in no time; while they continue to execute on different thread.

In general, asynchronous programming makes sense in two cases as:•
• If you are creating a UI intensive application in which user experience is prime concern. In this case, an asynchronous call allows the user interface to remain responsive. Unlike shown in Figure 1-1.

  • If you have other complex or expensive computational work to do, you can continue; interacting with application UI while waiting for the response back from long running task.  Read Full Article Here…
