Building Secure gRPC Services in ASP.NET Core

Modern microservices demand lightning-fast, secure, and efficient communication pathways. Traditional REST APIs often fall short under heavy loads, making gRPC the go-to framework for high-performance service-to-service communication.\n\nThis text-based course guides you from the fundamental concepts of Remote Procedure Calls (RPC) to implementing robust, secure gRPC clients and servers in ASP.NET Core. You will learn how to define contracts, optimize payloads, and secure your endpoints using industry-standard protocols.\n\nWhat you'll learn:\n- Understand the core architecture of gRPC and how it compares to REST\n- Write and structure Protocol Buffers (protobuf) schemas for clear service contracts\n- Configure high-performance gRPC clients and servers in ASP.NET Core\n- Implement transport security using TLS and authenticate connections with modern token-based flows\n- Apply gRPC JSON transcoding to expose gRPC services as RESTful APIs for legacy clients\n- Test and debug gRPC services using written code examples and command-line tools\n\nThe course begins with foundational concepts of RPC and Protocol Buffers before moving into hands-on configuration of client-server communication. You will then explore advanced security implementations, modern API transcoding techniques, and best practices for production deployment.\n\nThis course is designed for backend developers looking to expand their API design toolkit. A basic familiarity with C# and ASP.NET Core is helpful, but no prior experience with gRPC or Protocol Buffers is required.\n\nStart reading today to build faster, more secure distributed systems.
