Building Code-First gRPC Services with .NET and C#

Traditional gRPC development often requires writing and maintaining complex Protobuf files before you can even begin coding in C#. By adopting a code-first approach, you can leverage your existing C# skills to build fast, type-safe APIs directly from your code.\n\nThis text-based course guides you through the entire process of designing, implementing, and consuming code-first gRPC services in ASP.NET Core. You will transition from manual API definitions to highly efficient, code-driven communication systems that integrate seamlessly with modern C# workflows.\n\nWhat you'll learn:\n- Understand the core concepts of gRPC and how the code-first approach differs from contract-first development\n- Configure ASP.NET Core applications to host and consume code-first gRPC services\n- Define service contracts and data contracts using native C# interfaces and data transfer objects\n- Implement streaming communication patterns, including unary, server streaming, and client streaming\n- Apply modern C# features such as async/await, nullable reference types, and dependency injection to your services\n- Share contracts efficiently between server and client applications to ensure compile-time safety\n\nThe journey begins with foundational gRPC terminology and architecture before moving into practical C# contract design. You will then explore service implementation, streaming techniques, and modern configuration practices through written explanations and structured code exercises.\n\nThis course is designed for .NET developers looking to modernize their API communication. No prior experience with gRPC is required, as we start with the essential basics.\n\nStart reading today to simplify your microservice communication with code-first gRPC.
