The .NET Compiler Platform, aka Roslyn, is the compiler for both the C# and the Visual Basic programming language.

This very session analyzes (pun intended) the Compiler APIs that not only expose information about the C# syntax within trees, nodes and tokens, but also offer the semantic model for accessing the compilation and its symbols. Additionally, we will utilize the APIs for Diagnostics and Workspaces, which serve as extension points for custom components:
- Diagnostic Analyzers: report diagnostics, such as warnings, that show up in CLI builds and as "squigglies" in your editor
- Diagnostic Suppressors: programmatically suppress non-error diagnostics
- Code Fixers: register "light bulb" code actions to fix diagnostics via `Ctrl+.` or `Alt+Enter`
- Code Refactorings: register diagnostic agnostic code actions
- (Incremental) Source Generators: emit additional C#/VB code to your compilation

But wait, there's more! Unit testing, code coverage, mutation testing, benchmarking, generating NuGet packages and Visual Studio extensions, and using nullable reference types within .NET Standard 2.0 compatible Roslyn projects.
As a bonus, I shall deliver a suite of (web) tools to kick-start your journey.

May the .NET Compiler Platform be with you.
