TFS Local Workspaces error -TF400030: The local data store is currently in use by another operation.

On a large Visual Studio project I started getting the following error message:

TF400030: The local data store is currently in use by another operation.

This project is using the local workspace feature of TFS, which has a lot of advantages, but has it own set of problems when your solution gets quite large(think 50.000 items or more).

I tried multiple solutions to solve the issue:

  • One possible solution is to delete the local workspace and recreate it again. This will clear the local version table, and allows you to start over with a clean slate. We noticed a small performance improvement after doing this.
  • An alternative could be to evaluate your current workspace and see if some server side folders should not be mapped. This can help decrease the size of your workspace.
  • Another option you have is to change back from a local workspace to a server workspace. As mentioned before, this option is useful only when your workspace contains a lot of items. In that case switching to a server workspace can help as they are proven to scale to up to 10,000,000 items in a single workspace.

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...
