Are there compatibility barriers with a .NET 4.0 assembly calling code in a .NET 2.0 assembly? And vice versa? More specifically, I'm investigating an upgrade to Visual Studio 2010 when using a third party application based on .NET 2.0. The application is extensible by hooks that reference my custom code.

UPDATE In the last update I could use SQLite for unit testing but not in an application run. That problem has now been resolved by modifying config to allow [loading from a remote assembly](http://msdn.microsoft.com/en-us/library/dd409252(VS.100.aspx) <runtime> <loadFromRemoteSources enabled="true"/> </runtime> in addition to ena...

What exactly does the .NET 4.0 runtime do if a .NET 4.0 executable contains a reference to a .NET 2.0 assembly? Is the .NET 2.0 assembly run with the .NET 4.0 runtime (in other words, .NET 4.0 must be 100% API-compatible to .NET 2.0) or does the process somehow host the .NET 2.0 runtime and some magic happens to make the .NET 2.0 types ...

I am using VS 2010 RTM and trying to perform some basic validation on a simple type using MetadataTypeAttribute. When I put the validation attribute on the main class, everything works. However, when I put it on the metadata class, it seems to be ignored. I must be missing something trivial, but I've been stuck on this for a while now. ...
