Add and run a WPF project to an existing solution

[n/a]

Hi,

This is a more general question, not about Telerik controls though I am using them.
(VISUAL STUDIO 2019)
I have a VSTO project (I think the question can be for Winforms projects as well).
I have a WPF project that I want to interact with from the VSTO project and back.
I managed to run (process.start with parameters) the the WPF exe from the VSTO but it's not good enough because I want to be able to communicate between the two projects.
I added the WPF project to the VSTO solution, and added a reference from the VSTO to the WPF and then create a "common project" that both projects reference to be able to pass data in common models.
I am able to run the WPF project from the VSTO (when the user clicks a button, in the UI of the VSTO, I call App.Main() in the WPF project).
The problem is that if I try to use App.Main() again (to call the WPF project again) I get an exception because I can not create a second Application in the appdomain.
Any thoughts on how I can accomplish this (my way or any other way that will let me interact between the two projects).
Thank you
Yaron
