What offers the recent versions of .NET technologies such as C#, ASP.NET MVC, WCF, WWF, WPF, Silverlight, LINQ, Entity Framework, OData Services, ASP.NET Web API…etc. for you

The some of the features of the Microsoft .NET recent versions 4 and 4.5 are given below.

1. Please note that each and every version of Microsoft .NET release tight, improve the security model and performance in various areas.

2. Microsoft .NET framework 4 introduces a new programming model called Parallel Computing for writing multithreaded and asynchronous code that greatly simplifies the work of application and library developers. This model enables developers to write efficient, fine-grained, and scalable parallel code in a natural idiom without having to work directly with threads or the thread pool. The new System.Threading.Tasks namespace and other related types support this new model. Parallel LINQ (PLINQ), which is a parallel implementation of LINQ to Objects.

3. In ASP.NET MVC, many features such as new Razor view engine, HTML 5 & Mobile supported templates, powerful hooks with Dependency Injection & Global Action Filters, OData Services, ASP.NET Web API, Asynchronous methods etc.

5. The Covariance and Contravariance in Generics.

In Covariance, Object=string.

In Contravariance, string=Object.

For example, In Covariance èClass Y: X then we can assign X = Y.

In Contravariance èClass Y: X then we can assign Y = X.

6. Dynamic Language Runtime:  DLR makes it easier to develop dynamic languages like LISP, JavaScript, PHP, and Ruby to run on .NET framework and add dynamic features to statically typed languages.  Dynamic is behaves like type Object in most circumstances and resolved at runtime.
