gRPC is a high-performance RPC framework that provides fast data size transmission while minimizing bloat. It offers flexibility in languages and endpoint-to-endpoint security. This post introduced gRPC basics and demonstrated its usage in a C# .NET project, showcasing protocol buffer consolidation in a shared assembly. Testing the solution allowed experience with running multiple projects from Visual Studio. Potential enhancements include adding methods for reporting weather alerts or implementing bidirectional communication. gRPC is a great addition to inter-process communications, making it suitable for various languages and applications.
