        Tool 'csharp-ls' failed to update due to the following:
        The tool package could not be restored.
        Tool 'csharp-ls' failed to install. This failure may have been caused by:

        * You are attempting to install a preview release and did not use the --version option to specify the version.
        * A package by this name was found, but it was not a .NET tool.
        * The required NuGet feed cannot be accessed, perhaps because of an Internet connection problem.
        * You mistyped the name of the tool.

Hey! It seems like you've got dotnet v5 installed, the csharp-ls package requires dotnet v6. Would you be able to upgrade your dotnet installation to v6?

[nyngwang]

Let me try it! I just saw your comment :) Wait a minute

@williamboman update: I'm using homebrew on macOS. The stable version I got brew info dotnet is v5. Is that dotnet-sdk, which has version 0.6, is it the same thing as you said?

Sorry for the ping! Just Resolved it from their README:

csharp-ls requires .NET 6 SDK to be installed. [...]

[nyngwang]

@williamboman: I got this error after I re-installed it today:

Spawning language server with cmd: `..../.local/share/nvim/lsp_servers/omnisharp/omnisharp/run` failed.
The language server is either not installed, missing from PATH, or not executable.

It seems like it's not related to upstream: https://github.com/neovim/nvim-lspconfig/issues/1719

chsharp_ls != omnisharp

[nyngwang]

@mjlbach: Yes but I finally resolved my problem by using omnisharp. But still thanks for the correction.
