You must have an ABP Business or a higher license to be able to create a microservice solution.

What is gRPC?

You can use gRPC to enable high-performance, low-latency communication between microservices. gRPC, or Google Remote Procedure Call, is an open-source remote procedure call system initially developed by Google. It uses HTTP/2 for transport, Protocol Buffers as the interface description language, and provides features such as authentication, load balancing, and more.

Learning Resources

The microservice startup template hasn't any configuration related to gRPC communication. You can see the following resources to learn how to implement gRPC calls between your services:

• Using gRPC with the ABP Framework (ABP Community article)
• Overview for gRPC on .NET (Microsoft's documentation)
• Code-first gRPC services and clients with .NET (Microsoft's documentation)
