Avalonia was a bit of a proof of concept for avoiding buildDotnetModule. addNuGetDeps is not well documented yet, so let me know if you have any trouble.

overrideFetchAttrs is there to allow fetch-deps to handle multiple target platforms (e.g. linux/darwin-x86/arm).

configurePhase should ideally do everything needed to get the nuget dependencies

buildPhase can call build.sh

linkNugetPackages and makeEmptyNupkgInPackages are hacks for things that don't handle NUGET_FALLBACK_PACKAGES properly or make other bad assumptions

can somebody with commit permissions take a look at this PR? https://github.com/NixOS/nixpkgs/pull/257489

I'd really want to get going on removing the deprecated buildDotnetPackage stuff, and this PR was blocking it for quite some time

Could someone please help me figure out how to get the dotnet sdk to work on NixOS? Neither wiki has any usable information on getting this setup, so I've basically just guessed at which packages I found when searching for 'dotnet' on search.nixos.org were the correct ones. The names of these seemed the most correct to me and thats all I picked based on, so if these aren't right please let me know

I have the following in my configuration.nix (removed the unrelated parts):

environment = {
  sessionVariables = {
    DOTNET_ROOT = "${pkgs.dotnet-sdk_9}/share/dotnet/";
  };
  
  systemPackages = with pkgs; [
    dotnet-aspnetcore_9
    dotnet-runtime_9
    dotnet-sdk_9
  ];
};

I've added the dotnet-sdk_9 dotnet root since the wiki said thats what to do if its not found, but that doesn't seem to have any effect. Its still not able to access the sdk unless I cd to that dir and use the filesystem local dotnet instead of the system one:

[ngupton@armadillo:~]$ dotnet --list-runtimes
Microsoft.AspNetCore.App 9.0.3 [/nix/store/7vpnwiiqjhlqg0d1ar7vk3fdis39xzlp-aspnetcore-runtime-9.0.3/share/dotnet/shared/Microsoft.AspNetCore.App]
Microsoft.NETCore.App 9.0.3 [/nix/store/7vpnwiiqjhlqg0d1ar7vk3fdis39xzlp-aspnetcore-runtime-9.0.3/share/dotnet/shared/Microsoft.NETCore.App]

[ngupton@armadillo:~]$ dotnet --list-sdks

[ngupton@armadillo:~]$ cd $DOTNET_ROOT

[ngupton@armadillo:/nix/store/6p8ca1aaj3hpswi1b12si274kf550hk1-dotnet-sdk-wrapped-9.0.202/share/dotnet]$ ./dotnet --list-sdks

Could someone please help me figure out how to get the dotnet sdk to work on NixOS? Neither wiki has any usable information on getting this setup, seems to assume you're trying to build a dotnet nix package instead of actually use dotnet on your system.

Ah finally got it figured out, changing the packages to the following fixed it

systemPackages = with pkgs; [
  (with dotnetCorePackages; combinePackages [dotnet_9.sdk dotnet_8.sdk])
];

corruptcomputer: ```
environment = let
dotnet-sdk = with dotnetCorePackages; combinePackages [ sdk_9_0 sdk_8_0 ];
dotnetRoot = "${dotnet-sdk}/share/dotnet";
in {
etc = {
"dotnet/install_location".text = dotnetRoot;
};

systemPackages = with pkgs; [
dotnet-sdk
];
};

corruptcomputer:

environment = let
dotnet-sdk = with dotnetCorePackages; combinePackages \[ sdk\_9\_0 sdk\_8\_0 \];
dotnetRoot = "${dotnet-sdk}/share/dotnet";
in {
etc = {
"dotnet/install\_location".text = dotnetRoot;
};

systemPackages = with pkgs; \[
dotnet-sdk
\];
};

corruptcomputer:

environment = let
  dotnet-sdk = with dotnetCorePackages; combinePackages [ sdk_9_0 sdk_8_0 ];
  dotnetRoot = "${dotnet-sdk}/share/dotnet";
in {
  etc = {
    "dotnet/install\_location".text = dotnetRoot;
  };

  systemPackages = with pkgs; [
    dotnet-sdk
  ];
};

this is what I do in my config: https://github.com/GGG-KILLER/nixos-configs/blob/3553a0247d667bd3d83937e52d63625ba592c1c5/hosts/sora/system/programs/default.nix#L10-L18
