How to trigger a UIPath project from a Visual Studio Application

Hello guys,
My intention is to create a C# application on Visual Studio and import the .nupgk that the UIPath Studio export, to build some app where the user can trigger some UIPath project by pressing a button.

However I’m getting this error when trying to import the nupgk:

I tried to update the netcoreapp to a new version, but the error is still there.
Someone have some idea of how to solve it?

I build a application using the Robot API and it worked, and also saw the page that explains how to use the WCF Service in Visual Studio to trigger some UIPath project, but now I’m tryind to build all locally.
