No need to wait for .Net 5 to start using code generation with Roslyn

Recently, when I was reviewing the new features that are going to be included in .Net 5, I came across an interesting one — C# Source Generators. This feature especially interested me since I have been using a similar approach for the last… 5 years and what Microsoft proposes is simply a deeper integration of this approach into the build process.

Further I’ll share my experience using Roslyn in code generation and I think this will help you better understand what exactly Microsoft offers and when you can use it.

First, let’s look at a typical code generation scenario. You have some external source of information such as a database, a JSON description of some REST service, another assembly (via reflection) etc. And using this information you can generate various types of source code such as DTOs, db model classes or proxies to REST services.

Source generators are a new feature of the C# compiler that enables inspecting user code using compiler-generated metadata and generating additional source files to be compiled along with the rest of program.

Learning C: Input and Output and Two Program Templates

Learning C: Input and Output and Two Program Templates. Besides demonstrating how to perform input and output in C, I will also be demonstrating two templates that are related to those topics — Prompt, Then Read and Input, Process, Output (IPO). The IPO template, in particular, is important because practically every C program you write will use this template.
