Discovering Visual Studio 2026 – Code coverage

Yes! The new Visual Studio 2026 edition is available in preview (now called Insiders). I'll take some time this week to walk through some of the features I like and maybe some of the rough edges I discover along the way.

Today I want to take a look at Code Coverage in Visual Studio. “Wait… what?!” I here you think, “Code coverage is not a new feature in Visual Studio.”. And yes you are right, But until this version Code Coverage was only available for the Enterprise Edition of Visual Studio.

With Visual Studio 2026, it is finally a part of the Community and Professional Edition as well. (I always thought it was strange to call yourself professional but don’t focus on code coverage.)

How to use Code Coverage in Visual Studio

So, if you never had the opportunity to use the Code Coverage feature in Visual Studio, let me walk you through the steps.

Go to the Test menu and select the Analyze Code Coverage for All Tests option from the menu.

Another option is to right click on a set of tests in the Test Explorer and select the Analyze Code Coverage option from the context menu.

Once the code coverage analyzer has completed its job, you can see the results on the Code Coverage Results window.

Here you can see the coverage percentage on Assembly, Class and Method level.

The coverage percentage can also be highlighted in the editor making it really easy to identify what parts of your code are still missing tests. Therefore, click on the Show Code Coverage Coloring icon in the Code Coverage Results window:

 

I’m really happy that this feature finally made it into all editions.

Podman– Command execution failed with exit code 125

After updating WSL on one of the developer machines, Podman failed to work. When we took a look through Podman Desktop, we noticed that Podman had stopped running and returned the following error message: Error: Command execution failed with exit code 125 Here are the steps we tried to fix the issue: We started by running podman info to get some extra details on what could be wrong: >podman info OS: windows/amd64 provider: wsl version: 5.3.1 Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM Error: unable to connect to Podman socket: failed to connect: dial tcp 127.0.0.1:2655: connectex: No connection could be made because the target machine actively refused it. That makes sense as the podman VM was not running. Let’s check the VM: >podman machine list NAME         ...

Cache stampede: when our cache turned against us

While investigating some performance issues, we ran into an ASP.NET Core API that cached a fairly expensive aggregation query for 60 seconds. Under normal load, that was fine: one request rebuilds the cache, everyone else reads from it. Under peak load, dozens of requests would arrive in that same expiry window, all see a cache miss, and all fire the same expensive query in parallel. The database didn't like that. That was the moment when our caching layer stopped helping and started hurting. A burst of requests comes in at the same time, all miss the cache, and all go hammer the database or the downstream API at once. That's a cache stampede . The cache was supposed to protect our backend, and for a few hundred milliseconds it did the opposite. Why this happens IMemoryCache.GetOrCreate (and its async sibling) looks like it protects you, but it doesn't add any locking on its own. Look at the naive version: public async Task<Report> GetReportAsync(string key) ...

A complex system designed from scratch never works

A few years ago, I worked as an architect on a big mainframe rewrite. I still count it as one of my failures. Not because the technology was wrong, but because I couldn't convince the management team to simplify the approach. Years later, the organization is still struggling to get the new system up and running. I left the project at the time, because I couldn't put my name behind an approach that would take very long and cost a lot of money without a working system to show for it along the way. Gall’s Law That memory keeps coming back to me, because it's a textbook case of Gall's Law playing out in real life. Gall's Law , from John Gall's Systemantics , states it plainly: A complex system that works is invariably found to have evolved from a simple system that worked. A complex system designed from scratch never works, and it cannot be patched to make it work. You have to start over with a simple system that works. What does that mean in practice,...
