Source Generators & Roslyn APIs

Write incremental source generators that run at compile time to eliminate boilerplate, validate code, and generate optimized implementations.

Part 1: Introduction to Source Generators & Roslyn APIs

This lesson covers Write incremental source generators that run at compile time to eliminate boilerplate, validate code, and generate optimized implementations.

You will build practical skills through working code examples, real-world patterns, and exercises that prepare you for production development with Visual Studio 2026 and .NET 10.

Part 2: Core Concepts

// Source Generators & Roslyn APIs — Core C# 14 / .NET 10 Example
public class Example32
{
    // Implementation covered in this lesson
    public async Task<string> DemoAsync()
    {
        await Task.Delay(1);
        return "Lesson 32 complete!";
    }
}

Part 3: Key Patterns & Best Practices

Apply the patterns from this lesson consistently in your codebase. Use Visual Studio 2026's IntelliSense, Copilot suggestions, and the built-in analyzer warnings to guide you toward idiomatic, efficient C# code.

Part 4: Next Steps

Practice the concepts from this lesson by writing your own examples. Then move on to Lesson 33 to continue building your C# expertise.
