Do you have apps that need to move to .NET 5? Carl and Richard talk to Mark Rendle about his work on Visual Recode, which started out as a migration tool for WCF to gRPC, but has evolved to deal with the migration to .NET 5 challenges. Mark talks about how older WCF apps can often move to gRPC pretty easily, but moving the app has other problems, like out-of-date libraries, build practices, tests, and so on. There's also the possibility of migrating WebAPI and even WebForms apps - lots of possibilities!
