.Net 1.1 add in won't debug in Visual Studio 2003 after installing SolidWorks 2009

Hi,

I previously used Visual Studio 2003 and SolidWorks 2003. In this environment I had developed an add in that worked fine. I have a stand alone application that references this add in so that users of the standalone app can start procedures in the add in.

Dim

addinInterface As New Test.Application

addinInterface = gSWApp.GetAddInObject("{B05A71C1-CC8D-4AE8-86A6-9924C9D507C9}")

addinInterface.smoothSurface(gOrgStemComponent.Name)

This worked fine with my original setup with VS 2003 and SW 2003. After installing SW 2009 I get an error that the Test.Application: "Implementing class 'Test.Application' cannot be found." I figured I somehow had to add a reference to the dll again. But when I try to do this again I get an error telling me that it cannot be added as: "Converting the type library to a .Net assembly failed. Error loading type library/DLL."

I suspect it might have something to do with the fact that SW 2009 installed .Net 2.0 (or was it 3.0?).

Anyone had this problem? Help is appreciated.

Best regards
