WCF migration

[aramacciotti]

Few questions about the statement "Migrate a WCF solution to gRPC":

1. Is it possible to reach gRPC service using a "net.tcp" protocol endpoint?
2. Am I correct that any existing client needs at least to change namespace of the old client instance to reach the gRPC migration result?
3. May I call a gRPC .Net Core server from a .NET Framework client and which is the way to add the relative Connected Service? Have I to point out the .proto file as for a .Net Core client?
