Configure Visual Studio 2019 to use SourceLink

Source Link allows developers to debug the source code from libraries they are using. Tools like Visual Studio can step into its source code what helps you find out what is going on behind the scenes. Let’s see how we can enable SourceLink debugging in Visual Studio:

  • Go to Tools > Options > Debugging > Symbols and check if the  ‘NuGet.org Symbol Server’ option is checked. It is recommended to specify a local directory that can be used as a symbol cache to avoid the need to download symbols every time:

  • Disable 'Just My Code' in  Tools > Options > Debugging > General to make the debugger load symbols that are not part of your current solution. Also check that the  'Enable Source Link support' is set (which should be the case by default):

  • When you now try to debug code, you can step into the code through F11. Visual Studio will ask you to download the corresponding source code:

Troubleshooting

In case you get a ‘File Dialog’ asking you to specify the source location, it can be the case that you don’t have access to the source repository.

In that case click on ‘Cancel’ in the dialog. You’ll end up on the 'Source Link Authentication failed' window. Here you can try to authenticate (again) by selecting the 'Authenticate with Source Link' option from the list of available actions:

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) ...
