TFS 2012 Test migration: be careful when switching between environments

For a customer I’m preparing the migration process from TFS 2010 to TFS 2012. To test the migration, we did a test upgrade from TFS 2010 to TFS 2012 on a separate server.

This allows to test the new behavior in isolation, validate if our customizations still work and hopefully save us some time when doing the production migration.

One thing we struggled with is that we couldn’t switch back to the old TFS 2010 environment after connecting to the TFS 2012 environment. Same problem when trying to connect to the old build server after connecting to the new one.

Instead Team Explorer showed a HTTP code 404: Not Found message.

The solution for everything: clear the cache.

The solution is simple. It looks like Visual Studio is caching some information about the TFS servers. Because these servers are almost the same, I guess that Visual Studio mixes up some things.

To fix it, you have to clear the cache folder located at: C:\Users\userName\AppData\Local\Microsoft\Team Foundation\4.0\Cache

Afterwards you should be able to connect again…

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         ...

Cleaner switch expressions with pattern matching in C#

Ever find yourself mapping multiple string values to the same result? Being a C# developer for a long time, I sometimes forget that the C# has evolved so I still dare to chain case labels or reach for a dictionary. Of course with pattern matching this is no longer necessary. With pattern matching, you can express things inline, declaratively, and with zero repetition. A small example I was working on a small script that should invoke different actions depending on the environment. As our developers were using different variations for the same environment e.g.  "tst" alongside "test" , "prd" alongside "prod" .  We asked to streamline this a long time ago, but as these things happen, we still see variations in the wild. This brought me to the following code that is a perfect example for pattern matching: The or keyword here is a logical pattern combinator , not a boolean operator. It matches if either of the specified pattern...
