service-definition

Design gRPC proto files for .NET microservices by structuring command and query contracts with clear package conventions, enforcing proper proto naming rules, and defining messages that map cleanly to domain models. This prevents inconsistent service contracts and runtime serialization errors.

Handle nullable fields and timestamps in protobuf by using google.protobuf wrappers for nullability and the Timestamp type for DateTime values. This ensures accurate runtime serialization and prevents mapping errors in C# microservices.

Yes, you can use MediatR handlers with gRPC service implementations by inheriting generated C# Base classes and delegating incoming requests to MediatR commands and queries. This keeps business logic out of the service layer entirely.

The best way to register gRPC services in a .NET application is using the MapGrpcService registration pattern. This correctly wires up generated service stubs, interceptors, and pagination messages for accurate runtime execution.

Yes, this gRPC service definition approach supports pagination patterns by providing specific message structures and mapping extensions. These patterns ensure efficient data retrieval over gRPC contracts without leaking business logic.
