Recently Microsoft made Visual Studio 2010 available to MSDN Universal subscribers, and will shortly make it available to the general public as well. Previously this had only been available as a closed MVP limited CTP downloadable on Connect.
Visual Studio 2010 provides some really attractive advances, particularly in the area of dynamic languages (F# now being a full-fledged Visual Studio language choice), Workflow (with a brand new workflow engine), Cloud computing (Azure), and – for Silverlight developers – not only is there now a full interactive drag-and-drop designer window, but you can choose whether you want to develop with Silverlight 2 – or Silverlight 3 – all from the same IDE!
I’ve installed this on my primary development desktop machine alongside Visual Studio 2008, and while it hasn’t been long enough (only 2 days) to make firm determinations, so far I have not seen any “interferences” from having both products installed at all.
A FIX FOR .NET FRAMEWORK 1.0 ISSUES
On my laptop, Visual Studio 2010 and the .NET Framework 4 Beta installers failed, claiming that I had to remove .NET Framework 1.0 first. Unfortunately for me, it would not uninstall. Aaron Stebner to the rescue, once again! This Microsoftie knows more about installer issues than God, I swear! You can download his “.NET Framework Cleanup Tool”, run it, and it will take care of everything. Once that is done, you will be able to install Visual Studio 2010 and the .NET Framework 4.0 Betas.
