Clean up your Visual Studio bin folder by using Powershell

Every once in a while,  my hard disks got filled up.Today it happened again. I knew that a lot of disk space was eaten up by compiled code living inside the bin folder of all my projects. After a rough estimate I ended up with 12 GB of compiled code! I could have started by opening up every project folder and manually delete every bin folder. Luckily Powershell just made that job a whole lot easier.

Here’s the command to remove all obj & bin folders from a path (assuming you’re in the path now):

   1:  Get-ChildItem .\ -include bin -Recurse | foreach ($_) { remove-item $_.fullname -Force -Recurse }

If you’re not in the correct folder just replace .\ with the full or relative path. You’ll still need to close down Visual Studio first, the -Force switch will override permission failures, but not process locks.

Note: this does a forced delete without prompting for confirmation, so you’d better be really sure you want it all gone. If you don’t want to take any risk first add  -WhatIf after the last -Recurse to do a dry run first to see what will be deleted, i.e.:

   1:  Get-ChildItem .\ -include bin -Recurse | foreach ($_) { remove-item $_.fullname -Force -Recurse -WhatIf

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...
