• Learned about some concepts of gRPC services, how they work, and their benefits.
• Implemented a simple gRPC service.
• Implemented a gRPC service that uses an EF Core model that cannot yet use AOT publish.
• Implemented a gRPC service that uses SqlClient libraries that can use AOT publish and are therefore smaller and faster.

• Implemented a custom decimal type and used extended date/time types.
