Martin Stühmer

Hello there, I’m Martin, software architect and developer from the Stuttgart region. Right from the start of my professional career, I decided in favor of .NET and Microsoft technologies and tools and have always incorporated them into my work. With more than 15 years of experience in the field of software architecture and development with .NET, my focus is particularly on increasing the quality and performance of development teams, the interaction of the software solution with the target environment and the actual application down to the last byte.

In my position as Director Consulting Services @ CGI, I act as enterprise architect and developer for cloud native and .NET solutions. I am also a trainer for cloud and software architecture. In addition to my professional life, I am involved in the open source communities and currently provide them with various NuGet packages with different focuses and functionalities.

A strong willingness to learn and develop is also part of my everyday life. This was taken to a new level for me in 2021 after I successfully completed my IHK trainer and my Microsoft certified trainer this year. In addition, I was able to qualify as a trainer for CGI’s Risk and Cost Driven Architecture program in 2022.

NetEvolve.HealthChecks 5.0: 27+ Targeted Probes, Zero Boilerplate

NetEvolve.HealthChecks 5.0 is a decisive expansion—broader coverage scope, less boilerplate.

New domain‑specific packages extend monitoring across cloud services, messaging platforms, graph, time‑series, vector and AI backends. In parallel, the former inheritance‑driven shared base library (abstract classes + repetitive DI wiring) was replaced by purpose-built source generators—removing manual registration churn and consolidating intent. Release 5.0 also formalizes full support for .NET 10—aligning with current trimming and analyzer improvements.

.NET 10 Testing: Microsoft Finally Fixed the Test Runner (Mostly)

.NET 10 replaces VSTest with Microsoft.Testing.Platform, bringing SDK-integrated testing with faster discovery, consistent behavior across environments, and explicit configuration contracts. But it requires .NET 10, breaks old test adapters, and demands CI pipeline discipline. Here’s what actually changes, who should migrate now, and who should wait.

Code Metrics and Configuration: Beyond the Numbers Game

Code metrics have become a standard feature in modern development environments, yet their implementation and interpretation often leave much to be desired. While Visual Studio and .NET provide comprehensive code metrics analysis, the way these metrics are configured, presented, and (more critically) acted upon reveals a fundamental disconnect between measurement and meaningful improvement.

What code metrics actually measure, how to configure them properly, and (more importantly) why blindly following thresholds without understanding context is, frankly, a recipe for misguided refactoring efforts that waste your team’s time and actively damage your codebase.
