Visual Studio 2010 Beta2 says "The application cannot start."

We have been having this issue with Visual Studio 2010 Beta2. It just stops loading. For some it stops loading unless you load it via loading a solution, others it's the opposite.

We can't move to the RC2 until we it supports Silverlight 4 properly..

The solution?

We have had some success by just loading up a visual studio command prompt and running:
devenv /ResetSettings

Also try:
devenv /reset
devenv /resetuserdata

Give it a go. Let me know how you get on :)
(It might also be worth backing up your currentsettings.xml file first)

Did you know that there is a way to trick SL4 into installing onto an installation of VS 2010 RC?

See this blog post: Enabling Silverlight 4 on Visual Studio 2010 RC.

Rob & I are quite merrily developing a SL4 app using VS2010 RC after following the above steps.

I did see that actually. We may have to give that a go. Especially as ReSharper isn't supported on the Beta2 any more.. and I only have 10 days left on the EAP version I have.

One thing to bear in mind is that Expression Blend for .NET 4 currently doesn't support projects created in VS 2010 RC ... so by moving to RC you'll break Blend support, for the moment at least.

Damned if you do, damned if you don't :-(
