GRPC Server & Client example with C#

• Customer & Greet Service with a couple of getters.
• In order to make it run you have to keep the proto files (client & server) in sync.
• Make sure that you rebuild your solution every time you modify the proto buffers, so you can override the methods to generate a valid response.
• Remember to update the Configure method of the Startup class every time you add a new service.

When should I use GRPC? Microsoft suggests a couple of use cases:

• When dealing with IoT devices, since they may be memory|bandwidth|hard-drive space restricted. Those devices are good candidates to use GRPC because it allows really tight small quick communications between client-server and back.
• Microservices: considering that they have to communicate with each other asynchronously and in a near time but not in real-time using something like a message queue.

Advantages?

• More efficient that Web REST APIs.
• Simpler to do, there are a lot fewer footprints in some ways.

Disadvantages?

• The need of sharing a proto file: in an API you only expose a call and there it is.
• Almost every device in the world can consume an API, that's not the case for GRPC.
