From Zero to Hero: gRPC in .NET

author
by Irina Scurtu

Learn how to build gRPC applications in .NET using C#

gRPC (gRPC Remote Procedure Calls) is a high-performance remote procedure call framework initially created by Google. Since its public release, it has become one of the three most popular approaches to building APIs, not just in .NET but in any programming language (the other two being REST and GraphQL). Its use of Protocol Buffers, Bi-directional streaming, and integrated auth has made it one of the most performance and most popular frameworks, especially regarding internal service communication. It is used by companies like Google, Netflix, Square and Cisco, to name a few, and it is also part of the Cloud Native Computing Foundation. .NET has incredible first-party support for gRPC, and every .NET engineer should know how to utilize it to build scalable, clean and performance applications with gRPC. In this course, Irina Scurtu will take you from the very basics of gRPC to some advanced concepts on how to build and run gRPC applications.
