Hi I recently installed DotNetNuke 5.5.1 When I right click on the website and select Property Pages then Build it show the Target Framework as 4

I created as usercontrol which references an assembly I created. The assembly targets framework 4 also.

When I run the site I get:

Could not load file or assembly 'MyAssembly' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.

Seems strange because the frameworks match. When I change the assembly referenced by the usercontrol to target framework 3.5 it works.

Can anybody tell me what is causing this and suggest a fix?

Thanks!

By chance are you running the AppPool as .Net3.5?
