A number of people have asked me about resources for VS2010 & .NET 4.0.

When Microsoft released the betas, they also created a set of new forums and documentation.

A great starting place is the Visual Studio 2010 and .NET Framework 4 Beta 1 developer center. Here you'll find links to mostly all of Microsoft relevant resources including downloads related to VS2010 and .NET 4, forums and documentation. I'll highlight some of the most used resources.

Forums

Understand that not all of these forums are solely for VS2010/.NET. Most of those that are specific to the beta have an indication in the forum name or description.  For example,

Visual Studio Editor
Discuss and ask questions about the Visual Studio Editor in Visual Studio 2010 Beta 1

However, if you look at the VB forum, there's a message at the top that specifically says "For VS2010 questions, please us the tag VB2010". Surely the 14,000+ threads on this forum are not from the recent beta!

On the other hand the EF Pre-Release forum does seem to have started with the beta.

Documentation

There are specific sections in the docs just for VS2010 and .NET 4 beta.

When you are viewing documentation, note that the url for the new docs include "(VS.100)" in them. For example,

http://msdn.microsoft.com/en-us/library/w0x726c2(VS.100).aspx

is the url for the .NET 4.0 documentation starting point.

Don't miss:

• What's New in Visual Studio 2010

• What's New in Beta 1 for Visual Studio Team System 2010

• What's New in the .NET Framework 4

I can't help but highlight the direct link to the EF4 documentation. :-) Start in the .NET Framework 4 Beta 1 section and drill in.

This should get you started. Of course there are a ton of blog posts and articles and other content coming out on .NET 4/VS2010 outside of the MSDN resources.
