Why is Sharepoint 2010 restricted to .Net 3.5?

I just came in contact with development for Sharepoint 2010. What I don't understand is: why are all Sharepoint project restricted to use the .Net 3.5 framework?

I understand that Sharepoint 2010 is developed on top of framework 3.5 but why cant i reference Sharepoint 2010 dlls in a .Net 4.0 project? For example the Client Object Model?

As I understand it a .Net 4.0 project can use .Net 3.5 Assemblies without problems normally. Why doesn't this work for Sharepoint 2010 assemblies?

Thanks for your help! Rocko

What kind of project is this?

If it is a WebPart or WorkFlow project then it would be running under a SharePoint 2010 instance, and that would therefore require .NET 3.5.

A partial solution I have seen is to create a .NET 4.0 WorkFlow hosted on Windows AppFabric ( http://msdn.microsoft.com/en-us/windowsserver/ee695849.aspx ) , with which SharePoint 2010 can interact with fairly easily.
