Can not use Corel Draw 2020 Visual Studio editor to edit a VSTA application

Question

I want to use Corel Draw 2020 Visual Studio editor to write a script and it could start Visual Studio. But when I click the button "start", a dialog box will appear and show this error:

Cannot start debugging. Pre-debugging negotiation with Host failed

I have no idea to solve it.

Answer 1

You cannot run your VSTA program from Visual Studio. Run this "macro" from CorelDraw after editing and compiling your C# class.
