Help with c# OmniSharp lsp configuration in ubuntu

[theArianit]

I am following the zed docs to configure the omnisharp lsp, I also downloaded omnisharp-linux-x64.tar.gz and did run it. I installed mono-complete for it to be able to run it. But when I open Zed it gives me this error
`Language server omnisharp:

initializing server omnisharp, id 2
-- stderr--
Could not locate MSBuild instance to register with OmniSharp.`

And the log says:
2025-08-19T23:56:41+02:00 INFO [lsp] starting language server process. binary path: "/home/arianit/.local/share/zed/node/node-v22.5.1-linux-x64/bin/node", working directory: "/home/arianit/.config/zed", args: ["/home/arianit/.local/share/zed/languages/json-language-server/node_modules/vscode-langservers-extracted/bin/vscode-json-language-server", "--stdio"] 2025-08-19T23:56:41+02:00 ERROR [lsp] cannot read LSP message headers 2025-08-19T23:56:41+02:00 ERROR [lsp] Server reset connection for a request "initialize" id 0 2025-08-19T23:56:41+02:00 ERROR [lsp] Shutdown request failure, server omnisharp (id 2): server shut down 2025-08-19T23:56:41+02:00 ERROR [lsp] Broken pipe (os error 32) 2025-08-19T23:56:41+02:00 ERROR [project::lsp_store] Failed to start language server "omnisharp": Error { context: "initializing server omnisharp, id 2", source: "Server reset the connection", } 2025-08-19T23:56:41+02:00 ERROR [project::lsp_store] server stderr: Could not locate MSBuild instance to register with OmniSharp.

This is the settings.json file
"enable_language_server": true, "lsp": { "omnisharp": { "binary": { "path": "/home/arianit/.omnisharp/run", "arguments": ["optional", "additional", "args", "-lsp"] } } }

I also have the dotnet SDK installed on my machine, if that's important.

Am I doing it wrong? How should I do it the right way?
Thanks in advance for any help.

That better go into https://github.com/zed-extensions/csharp/ as not that many developers deal with CLR-related things in this repo.

My configuration is as follows, it works fine

  "lsp": {
    "omnisharp": {
      "binary": {
        "path": "/usr/OmniSharp",
        "arguments": ["-lsp"]
      }
    }
  }
