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         ...

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) ...

VS Code Planning mode

After the introduction of Plan mode in Visual Studio , it now also found its way into VS Code. Planning mode, or as I like to call it 'Hannibal mode', extends GitHub Copilot's Agent Mode capabilities to handle larger, multi-step coding tasks with a structured approach. Instead of jumping straight into code generation, Planning mode creates a detailed execution plan. If you want more details, have a look at my previous post . Putting plan mode into action VS Code takes a different approach compared to Visual Studio when using plan mode. Instead of a configuration setting that you can activate but have limited control over, planning is available as a separate chat mode/agent: I like this approach better than how Visual Studio does it as you have explicit control when plan mode is activated. Instead of immediately diving into execution, the plan agent creates a plan and asks some follow up questions: You can further edit the plan by clicking on ‘Open in Editor’: ...
