Try to update a little project created back in 2019. Oh I used WCF and WCF is gone. Learn about gRPC. Port the service to gRPC protobuf. Find all the nuget packages to get it working in C#. Fix the broken vcproj for proto files. Figure out a replacement for NetTcp. Try gRPC in C++. Learn to integrate vcpkg. Create overlay ports to fix conflicting libraries. Teach VS to compile proto files to cpp. Find out grpc c++ doesn't (yet) support unix domain sockets for IPC. Pick another protocol. etc etc
