Assembly Registration Tool (Regasm.exe)

Assembly Registration Tool (Regasm.exe)

Use this to register assemblies for COM Interop.

In something more like english, you can use this to make a .net dll look like a com in-process server. However, the .net assembly needs to be in the working folder of whatever tries to invoke it as a com object (weird but true).

To fix that, you need to register your object in the GAC. Then it can sit in a registered spot and be accessible everywhere, like an ordinary com server.
