.NET workloads fail to install #226107

JamieMagee · 2023-04-14T04:01:57Z

Describe the bug

Since .NET 5.0, .NET has shipped as a 'slim' SDK with support for optional workloads¹. Optional workloads are expected to be installed by the user.

Steps To Reproduce

Steps to reproduce the behavior:

nix-shell -p dotnet-sdk_6
dotnet workload install android

Error

A mapping of .NET workload to NuGet packages required is here:

@mdarocha thanks!

@Smaug123 it looks like you had more success with dotnet workloads in https://github.com/Smaug123/nix-maui. Would you be interested in upstreaming your work to nixpkgs?

Smaug123 · 2023-04-15T06:41:20Z

I'm afraid this isn't something I'd be happy to maintain - it mostly works but is definitely suboptimal and would probably be a decent amount of work to upstream.

mdarocha · 2023-04-15T09:25:48Z

If I'll find the time, I'll attempt to expand on @Smaug123's work

adamreed90 · 2024-02-29T03:44:00Z

Since the dotnet workload installer now supports installing to a user directory, could it be possible to simply relocate the dotnet-sdk nixpkg to user space?

Smaug123 · 2024-02-29T07:32:41Z

A possible spanner in the works: PublishAot pulls down some binaries from NuGet, and therefore fails out of the box on NixOS because the AOT compiler can't find the linker (or something like that, it's been a while). So there's always going to have to be some amount of Nix wrangling somewhere.

This makes me so very sad, I only recently started using NixOS and I am a .NET developer by trade, I want to daily drive this so badly :(

anpin · 2024-03-15T13:15:24Z

even if workloads are installed in user space they are still failing to build dotnet/sdk#37706

float3 · 2024-05-11T01:17:07Z

does no solution to this exist?

anpin · 2024-05-21T09:50:20Z

@float3 take a look at workaround here, seems to work for some

Describe the bug

It is currently impossible to install .NET workloads on NixOS:

❯ dotnet workload install maui
Unhandled exception: System.IO.IOException: Read-only file system : '/nix/store/as1j1inzdjdaca6gdcfdr2bdsppgr3px-dotnet-sdk-8.0.300/metadata'

   at System.CommandLine.Invocation.InvocationPipeline.Invoke(ParseResult parseResult)
   at Microsoft.DotNet.Cli.Program.ProcessArgs(String[] args, TimeSpan startupTime, ITelemetry telemetryClient)

Steps To Reproduce

Steps to reproduce the behavior:

Install the .NET Core 8 SDK: environment.systemPackages = [ pkgs.dotnet-sdk_8 ];
Try to install a workload: dotnet workload install maui
Observe error

Expected behavior

dotnet workload install maui should install the workload in a user-writeable location.

Additional context

According to dotnet/sdk#18823 this can be fixed by writing a file <DOTNET_ROOT>/metadata/workloads/<sdkfeatureband>/userlocal. https://discourse.nixos.org/t/dotnet-maui-workload/20370 contains shell code examples how to do that.

thanks, it helped me with android workflow

anpin · 2024-08-14T18:57:33Z

@EmVee381 have you found a workaround? Could you please share? Safely I never got it to work on my nixos machine

i use devenv, but you can use it similar way

is it clear? it is just copy pasted from from your link :) it works for me very well, you just define overrieded package in between "let" block then use it as package in your derivation or shell.nix or anything and set environment variable DOTNET_ROOT
edited: pkgs-stable is not needed it is another input for my devenv testing purposes :)

{ pkgs, lib, config, inputs, ... }:

let
  pkgs-stable = import inputs.nixpkgs-stable { system = pkgs.stdenv.system; };
  dotnet-combined = (with pkgs.dotnetCorePackages; combinePackages [
    sdk_8_0
  ]).overrideAttrs (finalAttrs: previousAttrs: {
    # This is needed to install workload in $HOME
    # https://discourse.nixos.org/t/dotnet-maui-workload/20370/2
    postBuild = (previousAttrs.postBuild or '''') + ''
       for i in $out/sdk/*
       do
         i=$(basename $i)
         length=$(printf "%s" "$i" | wc -c)
         substring=$(printf "%s" "$i" | cut -c 1-$(expr $length - 2))
         i="$substring""00"
         mkdir -p $out/metadata/workloads/''${i/-*}
         touch $out/metadata/workloads/''${i/-*}/userlocal
      done
    '';
  });
in
rec
{
  env.GREET = "avalonia";
  env.DOTNET_ROOT = "${dotnet-combined}";
  languages.dotnet.enable = true;
  languages.dotnet.package = dotnet-combined;
  packages = [
    pkgs.git
    pkgs.omnisharp-roslyn
  ];
