title: I need an alternative similar to System.Runtime.Remoting that is supported in .NET 5.0
body: <p>I have a current software product written in C# WinForms that I'm migrating to WPF .NET 5.0. I've almost got it all migrated, but one of the last projects to migrate is the remoting support for the app. This is intended for remote control from a client in an intranet, NOT Internet.</p>
  <p>The current version of the product uses .NET Remoting, however, I sadly have found that this is not supported in .NET 5.0.</p>
  <p>I've seen something about gRPC, but can't find anything to show me how to implement or whether there might be something more similar to .NET Remoting to use so that there are minimal changes required.</p>
  <p>Thanks in advance for your help!</p>
