Is it possible to create a COM object programatically . NET?

Question

Long story short, trying to build a 'Smoke Tester' application. I'd like to be able to dynamically be given "Hey, this COM assembly (guid, progid) should exist" and attempt to create the COM object via ProgId or guid.

I know how to [ComImport] classes, but instead I'm looking to do this programatically. Is this possible?

It is only possible to create them programmatically. What on Earth are you asking? You specify the CLSID guid or the ProgId, not both. Use Activator.CreateInstance(), passing the type returned by either Type.GetTypeFromProgID() or Type.GetTypeFromCLSID(). Do try to avoid "System.ReformatDisk", if you don't know what it does then it probably does something you don't want. — Hans Passant

ROFL - I meant that I'd like to create from GUID or ProgID, depending upon what is handed to me via the interface. GetTypeFromProgID + CreateInstance is what I was looking for, thanks! — John

Call Activator.CreateInstance(Type.GetTypeFromProgID("progid")) (or Type.GetTypeFromCLSID).
