I installed Rider hoping to move away from Visual Studio Mac for a Xamarin project. Before installing Rider the project built successfully in VS Mac. After installing Rider, I opened the project and Rider reported over 300 errors and would not build. The errors were all related to "missing references". I switched back to Visual Studio Mac and got the same errors. I ultimately decided to remove Rider and now my project builds no problem in Visual Studio Mac.
I really want Rider to work but this experience did not fill me with confidence.
