![Weekly Recap: GitHub Copilot CLI, MCP in C#, and Modular Monoliths [July 2026]](https://devleader-d2f9ggbjfpdqcka7.z01.azurefd.net/media/SquareBanner.webp)
This week covers GitHub Copilot CLI workflows and permissions, MCP clients and servers in C#, and practical modular monolith design and testing. Plus, dig into production Roslyn analyzers and engineering leadership lessons on team culture, tech leads, and better questions.
Explore production-quality roslyn analyzer examples in C# -- naming conventions, null guard enforcement, and structured log validators you can adapt today.
Understand Roslyn analyzers vs incremental source generators -- how each hooks into the compilation pipeline and when to combine both in one NuGet package.
Master testing Roslyn analyzers using Microsoft.CodeAnalysis.Testing in C#. Learn NuGet setup, diagnostic markers, code fix testing, and CI integration.
This week covers GitHub Copilot CLI workflows and building Roslyn analyzers in C#. Plus practical guides to modular monoliths, MCP transports, production Serilog, NuGet debugging, AI's impact, and engineering leadership.
Learn when to use IOperation Roslyn vs SyntaxNode vs Symbol APIs. Compare the three analysis layers to pick the right one for your C# analyzer in .NET 10.
Master DiagnosticDescriptor C# configuration -- rule IDs, severity levels, .editorconfig overrides, and diagnostic messages for your Roslyn analyzers.
Learn to package and distribute your roslyn analyzer nuget package with the right folder structure, metadata, versioning, and CI/CD automation in .NET 10.
Build roslyn analyzer c# from scratch -- complete project setup, DiagnosticAnalyzer scaffold, CodeFixProvider implementation, debugging, and unit tests.
Learn what roslyn analyzers are, how they work in the .NET 10 compiler pipeline, why teams build custom diagnostics, and how to write your first rule in C#.
This week covers NuGet packaging from metadata and local testing through private feeds, versioning, and automated publishing. Plus practical guides to monolith architecture, MCP servers and clients in C#, Serilog, Roslyn analyzers, AI agent workflows, and senior engineering leadership.
