Dotnet 8

[BeauCranston]

Hopefully this is a quick and easy change but it would be nice to start working with new dotnet 8 projects

[anthonwellsjo]

Came here for this. Yes please 👍

[granitrocky]

Building locally and just changing the projects' TargetFramework key to net8.0 worked for me.

hey everyone!

sorry for not being able to respond, have a lot of things going in my life

if someone would push a PR i'd gladly test it. especially if it's just platform tfm change

I have the changes for dotnet 8 locally. I looked at the dotnet 7 PR and made sure to change the exact same things except for dotnet 8. I would be happy to make a PR but I don't think I have rights to do that

anyone with a github account can submit PR, unless there is something I don't know

or you could paste the patch here inline, unless it's more than 10 kb or so

[BeauCranston]

Didn't realize I had to fork the repo to pull request, first time contributing to an open source project. Pull request should be visible to you now

[razzmatazz]

thank you. I will take a look later to confirm this works for me as well.

csharp_ls stopped working for me in LunarVim after I installed 8.0 on MacOS. Tried removing Dotnet 8 manually and leaving only 7 and 6, but even afterwards it throws out an error and won't start:

Hoping the update will fix this, as LunarVim + csharp_ls are my main dev tools. Thank you for your work!

You don’t need to uninstall dotnet 8. Just create a global.json file in some parent directory above your repo and you cans specify a dotnet version and that will be the “active dotnet version” within the subdirectories of the global.json. Also you can clone the repo in, change the dotnet version and run the lsp locally and it will work.

Also you can clone the repo in, change the dotnet version and run the lsp locally and it will work.

So to be clear, here's what I did before I wrote my first message:

• installed .NET 8 on mac, which broke csharp_ls in LunarVim
• then uninstalled it (removed all .NET sdks manually and reinstalled 6 and 7)
• my global.json file in the home directory is set to this:

{
  "sdk": {
    "version": "7.0.404"
  }
}

But this doesn't change anything, the problem persists.

Could you give me some more info relating to the last sentence/possible solutions? Tried to ask people for help on different Vim discords, but no luck. Would appreciate a more step-by-step answer, if you find the time!

[BeauCranston]

Hmm sounds like something potentially went wrong when you removed the SDK's manually and there's some stuff hanging around. Have you run dotnet --list-sdks to see what comes up?

I would also try reinstalling csharp-ls in lunarvim if you havent already.

[BeauCranston]

The steps to make Dotnet 8 work locally:

• Clone/Fork the csharp-ls repo

• Modify the repo to use dotnet 8 (look at the dotnet 8 branch to see what I changed)

• uninstall any existing csharp-ls in your tools with "dotnet tool uninstall csharp-ls -g"

• if you are using Mason then ensure that csharp-ls is not an installed server in the lsp list

• in the local csharp-ls repo at /src/CSharpLanguageServer run "dotnet pack" followed by "dotnet tool install csharp-ls -g --add-source .\nupkg"

Now the global tool csharp-ls is your local copy.

• configure your lsp config to use your local copy here is my config:

  lsp={ servers={ "csharpls" }, config = { csharpls = function() return { cmd = {"csharp-ls"}; filetypes = {"cs", "razor", "csproj", "fs", "fsproj"}; root_dir = require("lspconfig").util.root_pattern(".sln", ".csproj", "packages.config"); } end, },

  },

The neovim distro I am using is astronvim but I am sure you can port it to your own distro. Also if you noticed I named the server csharpls instead of csharp-ls, this was so I can know that I am using my local version instead of the one from Mason.

Hopefully this works for you all in the meantime.

If you find yourself having trouble with this solution and want to revert you just need to run dotnet tool uninstall csharp-ls -g, and reinstall through mason again if you use it.

  				filetypes = {"cs", "razor", "csproj", "fs", "fsproj"};
  				root_dir = require("lspconfig").util.root_pattern("_.sln", "_.csproj", "packages.config");
  			}
  		end,
  	},
  },

Adding to this: If you want to use Mason (on Linux), you can go into .local/share/(your_nvim_appname)/mason/packages, delete whatever is in csharp-langauge-server folder and use the command:

dotnet tool install csharp-ls --add-source ./nupkg --tool-path $HOME/.local/share/{your_nvim_appname}/mason/packages/csharp-language-server

That should install your compiled version of csharp_ls to Mason with 8.0 update, following this guide.

Thanks @BeauCranston :)

Building locally and just changing the projects' TargetFramework key to net8.0 worked for me.

That doesn't do the trick on my end. Still fails with

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net8.0</TargetFramework>
    <OutputPath>bin</OutputPath>
    <OutputName>Program</OutputName>
    <OutputType>exe</OutputType>
  </PropertyGroup>
</Project>

With the LSP log error

:LspLog

C# code example here.

EDIT: On omnisharp everything seems to work as expected.

[Tyler-Hoyt]

Is there any progress on this? I don't want to be on visual studio anymore

[anthonwellsjo]

With the LSP log error

@Zeioth the log error probably indicates that you are still using the net7.0 version of csharp-ls.

Disabling any linter autoinstallation features, and then using JLCypher's suggestion above to point to your net8.0 version worked well for me.

[razzmatazz]

I have just upped v0.11.0 which contains @BeauCranston PR with update to dotnet 8, among other things. May take a couple of minutes to show up:

• https://github.com/razzmatazz/csharp-language-server/releases/tag/0.11.0

[Zeioth]

It works ok after the update thanks.

[j0of]

Hi there, I have run into a similar issue where I can't use some .NET 8 (or rather, C# 12) features within my project. For example, using primary constructors will give the error:

The feature 'primary constructors' is currently in Preview and *unsupported*. To use Preview features, use the 'preview' language version.

I'm using Neovim with mason, mason-lspconfig, and nvim-lspconfig. I can open a new issue about this if necessary.

[razzmatazz]

@j0of please do! Thank you!

I will close this one
