Dim b as object

Answer 1

If you're the ClassInterfaceType.None setting, You have to add a ProgId attribute to your class to allow late binding.

For example:

[Guid("B1E17DF6-9578-4D24-B578-9C70979E2F05")]
public interface _Class1
{
    [DispId(1)]
    string TestingAMethod();
}

[Guid("197A7A57-E59F-41C9-82C8-A2F051ABA53C")]
[ProgId("Rubberduck.SourceControl.Class1")]
[ClassInterface(ClassInterfaceType.None)]
public class Class1 : _Class1
{
    public string TestingAMethod()
    {
        return "Hello World";
    }

}
