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         ...

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...
