Call external classes (within an external DLL) while developping macro within SharpDeveloper

[utzmann_eric]

Hi,

I use Revit 2020 and I'm developing C# macro with SharpDevelop.

In such macro, I would like to use external classes which are into an DLL (not Revit API dll).

What I have done:

- go to 'preference' folder of my project

- try to 'add an external reference'.

- I've got an exception (see below)

I would like to know if it is possible, and how ? Is it a SharpDevelop bug ?

Thank you
