I think we do have an example dotnet core 6 project in the repo, but I agree - having a nice workshop would be great.
This was created whilst the latest incarnation was still in beta by a colleague:
https://github.com/DiUS/pact-workshop-dotnet-core-v3/pull/7
But after it went live there were a few additional changes and the workshop was made redundant. The PR above hopefully brings it a little closer in line, but it’s a bit much for me to review as I don’t know .NET all that well
