Do I need to compile my solution with VS2010 in order to benefit from .NET 4.0 new Code Access Security Policy?

Question

Hello,

I currently develop an application in C# with framework .NET 3.5 SP1.

In my app, I have satellite assemblies which are not in the same folder as the exe, and that causes me some trouble with FullTrust, as explained here.

In order to solve that problem, I wish to use .NET 4.0 whose Code Access Security Policy should allow my satellite assemblies to be FullyTrusted.

So my question is: is just installing the framework enough, or do I need to rebuild the solution with VS2010?

Thanks

To use anything in .net 4.0 you need to recompile the application to use the .net 4.0 runtime environment. Remember the .net runtime environments run side by side, so a 3.5 application will still use it's runtime environment (2.0) and not the newest one.
