We target .NET framework 2.0, but are upgrading our dev environments to Visual Studio 2010. Do we have to install the new Nevron Vision suite for VS2010, or is that really meant for .NET framework 4.0? If that's the case, then should we be installing the version that says it is for VS2005? Will there be any problems doing this, or is it really just a naming issue? 

Given that VS2010 (2008 too I think?) allows the developer to target a specific .NET framework, you may want to consider naming your releases to indicate framework rather than Visual Studio version. Unless of course, if I'm wrong and you are tying into specifics of the IDE.
