Dynamically invoke add-In method from VSTA macro

Has anyone been able to successfully invoke an add-in method from a VSTA macro? I have a C# SolidWorks add-in with a public method that I would like to invoke from a VSTA macro. Ideally, I would like to do this dynamically using Reflection so that my VSTA macro does not need a reference to the add-in assembly.

Thanks!
