Calling .net framework 2 from application developed in .net framework 4

I have an application developed using .net framework 4. I also have a DLL component developed in .net framework 2. Is it possible for me to call a component that was developed in .net framework 2? How do I do tha开发者_开发知识库t?

In general, yes. The .NET frameworks are 99% backwards compatible; very rarely are there breaking changes. Just add the DLL to your .NET 4 project as a reference as you usually do. If there are compile problems, post the specific errors.
