I am writing an application in C# which enters data to a third-party application using its tlb file. The third-party application is Rhapsody and the relevant files are: rhapsody.tlb, Interop.Rhapsody.com (the relevant third-party application in not important) Every version of Rhapsody holds different version of rhapsody.tlb file. My application should work with few versions of Rhapsody (7.4, 7.5.3, 7.6.1). My code (the methods I call) can work with every version of Rhapsody without any change. The problem is that I can build my code with only one tlb file. Therefore, the application can work properly only with one Rhapsody version. I can let the user to enter his Rhapsody version on startup (or using xml file). I can't use more than one exe file.
How can I execute the relevant tlb file during runtime (or build dinamically the file on runtime)?
