Async PDM API

I coded an addin for EPDM in C#.

In this addin, there is a feature pretty long. So I' would like display the feature progress.

To report the progressing, I use IProgress. The long task run async and the UI still responsive.

If I do a sandalone programme, referenced to PDM, it works like a charm. But I run it via IEdmAddIn5. It doesn't.

So before to go deeper, is it possible to run async stuff with pdm addin ?

Thank you
