What’s new in .Net 4.0 and Visual Studio 2010?


Microsoft has recently launched Visual Studio 2010 and .Net 4.0 Beta 1 with more expressive features. Some of them are mentioned below:

[New Language Support]
Visual F# is a new programming language which actually combines functional & object oriented programming to provide scalable language for .Net.

[Test Driven Development]
Visual Studio 2010 now offers greater support for test driven development where tests can be written before the actual code as an approach to the software design.

[Multi Targeting]
By using the multi targeting feature you can also create application of earlier version in new IDE of visual studio.

[Parallel Processing]
Using the new parallel extension of .Net 4.0 developers can create application which will scale efficiently as the number of cores & processors increase.

[Security]
The new framework improvements & expanded capabilities in the security model by simplifying the security policy. Now runtime support has been removed for enforcing the Deny, RequestMinimum, RequestOptional, and RequestRefuse permission requests.

[Performance]
.Net framework 4.0 beta 1 now provides improvement in the startup time and faster performance for multi threaded applications.

[Lazy Initialization]
By using this feature, the memory for an object is not allocated until it is needed. This improves the performance by spreading the object allocation across the lifetime of the application.

[In-Process Execution]
This enables an application to load & activate multiple version of the CLR inside the same process. Now you can run applications those are based on the .Net 2.0 & .Net 4.0 inside the same process.

[Profiler]
In the new framework you can now attach, run and detach profiling tasks at any point of time.

[Garbage Collection]
.Net Framework 4.0 now supports background garbage collection. In earlier frameworks it was a concurrent garbage collection.

[Collection & Data Structure]
- The new framework now includes BigInteger which supports all the standard numeric operation including the bit operation.
- It now supports self balancing SortedSet tree which sorts automatically after insert/delete operation.
- A new data structure named Tuple has been introduced in this framework which can hold an ordered set of heterogeneous items.

[Exception Handling]
The new CLR can now handle any exception regarding the corrupted state of the underlying operating system.
