Microsoft Visual Studio 2010 and .Net Framework 4.0 Beta 2 Is Out

October 19, 2009

Microsoft released the Visual Studio 2010 Beta 2 that comes with the new .Net Framework 4.0 Beta 2. The previous Beta 1 offered many interesting features that empowered parallel programming using the supported languages. However, the IDE had many important performance problems.Visual Studio 2010 Beta 1 offered a nice IDE. Nonetheless, I was very happy uninstalling this version today. Developers that want to create parallalelized code in order to translate multicore power into application performance need a fast IDE. So far, it seems Visual Studio 2010 Beta 2 solves many of the performance issues found in the previous Beta version. Besides, it allows working with a go live license. This means you can start using Visual Studio 2010 Beta 2 for production related work, considering the license agreement.

This new release changes the SKU line up. Now, you'll find the following versions:

Microsoft Visual Studio 2010 Express.

Microsoft Visual Studio 2010 Professional with MSDN. If you're going to create parallelized code with the new Visual Studio, this is the lowest version you should use.

Microsoft Visual Studio 2010 Premium with MSDN. Includes profiling and debugging, advanced database support and UI testing, among other features.

Microsoft Visual Studio 2010 Ultimate with MSDN. This version targets architects, testers and the most demanding developers.

The new names are similar to the different Windows 7 versions.

The new Beta 2 offers new project types. Now, you can target Windows Azure and Sharepoint with Visual Studio 2010. Besides, it supports ASP.NET MVC 2 and Silverlight 3.

There are some interesting improvements in the background garbage collection and in the Task Parallel Library that deserve the upgrade from the previous Beta version.

As this is the second Beta release, it's time to test the new performance improvements related to multicore programming. It is also a great opportunity to check whether this new version is prepared to allow developers to take advantage of the newest NUMA architectures, supported by both Windows 7 and Windows 2008 R2. The new framework offers many improvements in the Concurrency and Coordination Run-time and it also solves many bugs.

MSDN subscribers can download Visual Studio 2010 and .Net Framework 4.0 Beta 2 today (October 19th). Non-subscribers will have to wait for October 21st, just two days.

If you are an MSDN subscriber, you can log-in and download.

If you aren't an MSDN subscriber, check Visual Studio 2010 and .Net Framework 4.0 Web page and wait until Wednesday.

So far, you will have to wait until March 22nd for the final version. It's time to test the new features and improvements found in Beta 2!
