The correct version of the class is used based on the framework chosen for the application. You will see multiple version folders created under C:\WINDOWS\Microsoft.NET\Framework for all of the binary files.
I had trouble getting my ASP.NET 3.5 web site to work after installing .NET 3.5 on my server. You can't choose between .NET 2.0 and 3.5 in the asp.net tab in IIS; both run under 2.0. I had to add this section to my web config:
Finally it would compile my code with the new .NET 3.5 language features. New web.config files created in Visual Studio 2008 have this section, but it must be added to existing web sites before they will compile.
As for ASP.NET 3.5, it is still based on the ASP.NET 2.0 core fundamental.
Therefore, there is no new application type(for ASP.NET 3.5) in IIS, still
use the 2.0 one. And when you developing ASP.NET 3.5 application(which use
those 3.5 specific features such as AJAX or LINQ), VS 2008 will help you
add the proper assemblies reference in project and those assemblies are the
most imporant things to help you deal with 3.5 stuffs. And when deploy to
IIS, you still use 2.0 version tab to configure it.
If you have any further questions, please feel free to post here.
I have 3.5 installed on the server and I added the compilers section to my web.config as shown above, but i still get the error:
The type 'System.Data.Objects.DataClasses.EntityObject' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Entity, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
it runs perfectly on my test machine, what else could i be missing?
3.5 is "just an extension" of .net 2.0. So yes, you can run both on the same server. On a side note, this was one of the worst marketing things MS did with the framework. 1.0, 2.0 are major stand-alone frameworks. 3.0, 3.5 are extensions that require
2.0 to be installed. Although there was new features, IMO it should have been 2.1 and 2.5. Such as life. <rant over>

do they rewrite all the classes when they switch a framework or do they reuse it?
do they depend on each other?

3.5 is essentially an extension of 2.0.

Finally it would compile my code with the new .NET 3.5 language features. New web.config files created in Visual Studio 2008 have this section, but it must be added to existing web sites before they will compile.

Would you have to install 3.0 first, then 3.0 SP1, and THEN 3.5? Or can you just go straight to 3.5?

Check your web.config files:
You should add
<
add assembly="System.Data.Entity, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>@ assembly section.
