How to use com components.

Question

Hi

i hav created a COM component using vs2005 .

Now let me know can i use the dll which i have create on vs2005(which uses f/w 2.0) in vs2003(which uses f/w 1.1)??

Answer 1

In .NET projects add a reference into the "references" branch of the solution and a using directive into each file you want to use that component. In C++ projects use import directive.

Answer 2

I assume your real question is wether or not you can mix .NET versions in a single app as long as they use COM to interact.

I believe the answer is "no". An AppDomain can only have one .NET runtime loaded. Multiple runtimes is a feature of .NET 4.
