Overview of this book

Building Blazor WebAssembly Applications with gRPC will take you to the next level in your web development career. After working through all the essentials of gRPC, Blazor, and source generators, you will be far from a beginner C# developer and would qualify as a developer with intermediate knowledge of the Blazor ecosystem. After a quick primer on the basics of Blazor technology, REST, gRPC, and source generators, you’ll dive straight into building Blazor WASM applications. You’ll learn about everything from two-way bindings and Razor syntax to project setup. The practical emphasis continues throughout the book as you steam through creating data repositories, working with REST, and building and registering gRPC services. The chapters also cover how to manage source generators, C# and debugging best practices, and more. There is no shorter path than this book to solidify your gRPC-enabled web development knowledge. By the end of this book, your knowledge of building Blazor applications with one of the most modern and powerful frameworks around will equip you with a highly sought-after skill set that you can leverage in the best way possible.

What are source generators and how do they work?

Can you imagine code that writes code for you? With new features started in C# 9, such code is possible. Let’s dive into source generators, which can do exactly what the name says: generate source code.

Source generators are part of the .NET Compiler Platform (Roslyn) SDK, which makes them available everywhere dotnet code can be developed, no matter what IDE you use. The generators read code that you write and can generate some additional code that will be added to the compilation and emitted in the resulting .dll.

First, let me say what source generators can’t do. They can’t modify existing code. It is in the design of source generators to be able to add additional files to the compilation, but they can’t modify or remove existing files. Whether this is good or bad is a long-running discussion.

What source generators can do is they can read a compilation object representing all code that is being...
