C# devkit language server not working due to dynamically linked dependencies

[dannykruitbosch]

Hi,

Installing the C# devkit extension using the vs-code-marked-place does not work for me. I get this error when the extension tried to start

Unable to find extension target platform - no vsix manifest file exists at /home/danny/.vscode/extensions/ms-dotnettools.csharp/.vsixmanifest
Using dotnet configured on PATH
Dotnet path: /nix/store/m9dbas0s0a0lfgha03hb85cnb3r82bf2-dotnet-sdk-8.0.303/dotnet

NixOS cannot run dynamically linked executables intended for generic
linux environments out of the box. For more information, see:

As far as I can see, the extension should be patched for this already in the nix-vscode-extensions overrides, so there must be something else I am doing wrong.

Some help on how to fix this would be great.

@dannykruitbosch, how do you use this flake?

[griffi-gh]

Just use extension from nixpkgs, otherwise even if you work around this, it will fail because it tries to write into the extension directory.
Extension form nixpkgs is patched against this

Also experiencing this, shouldn't it be added to removed.nix?

@dannykruitbosch @griffi-gh @Toby222 please try using ms-dotnettools.csharp from nix-vscode-extensions (b051a4b or master).

With nix build github:nix-community/nix-vscode-extensions#extensions.x86_64-linux.vscode-marketplace.ms-dotnettools.vscode-dotnet-runtime I got:

Maybe *.sh?

./dist/install scripts/interprocess-communicator.sh
./dist/install scripts/install-linux-prereqs.sh
./dist/install scripts/determine-linux-distro.sh

I have this extension packaged in nixpkgs so you can get it from there.

Theoretically you should also be able to use usingFixesFrom but I haven't gotten that to work at all.

Alternatively, you can do what I do and override the src and version of the nixpkgs package with the ones from this flake:

@GGG-KILLER thanks, fixed the description of usingFixesFrom. Examples in the README should work now.

In case of ms-dotnettools.vscode-dotnet-runtime, you don't need to use usingFixesFrom since there are no specific fixes for this extension in nixpkgs.

Also, nix-vscode-extensions by default uses fixes from nixpkgs that you apply the overlay to.
