ASP.NET Core gRPC for WCF Developers

Introduction
gRPC is a modern framework for building networked services and distributed applications. Imagine the performance of Windows Communication Foundation (WCF) NetTCP bindings, combined with the cross-platform interoperability of SOAP. gRPC builds on HTTP/2 and the Protobuf message-encoding protocol to provide high performance, low-bandwidth communication between applications and services. It supports server and client code generation across most popular programming languages and platforms, including .NET, Java, Python, Node.js, Go, and C++. With the first-class support for gRPC in ASP.NET Core 6.0, alongside the existing gRPC tools and libraries for .NET Framework 4.x, it's an excellent alternative to WCF for development teams looking to adopt .NET in their organizations.

Who should use this guide
This guide was written for developers working in .NET Framework or .NET who have previously used WCF, and who are seeking to migrate their applications to a modern RPC environment for .NET Core 3.0 and later versions. More generally, if you are upgrading, or considering upgrading, to .NET 6, and you want to use the built-in gRPC tools, this guide is also useful.
