I have some assemblies in a solution one of which uses a ComImport. I would like to eliminate the ComImport as all the projects are in the same solution and simply reference but I keep getting errors that relate to the ComImport. Mainly when I reference the .dll it still thinks it is not referenced. How can I convert this to a standard interface that I can reference?
