Current behavior

When editing a xaml page there is no code completion

In the Uno Platform -XAML output windows it says this:

warn: Uno.LanguageServer.Workspace[0]
      No Roslyn worker is available

I'm on Ubuntu 20.04, I have .net 6 installed and the Uno Platform vscode extension installed.

uno-check does not report any problems.

Expected behavior

I expect to get code completion when editing my xaml files. I expect this because the Uno Platform vscode extension details says the following:

  • Code-behind navigation from a XAML file

How to reproduce it (as minimally and precisely as possible)

  1. Created a new uno project by exactly following the instructions here: https://platform.uno/docs/articles/get-started-vscode.html
  2. Try and edit a xaml file
    -> no code completion

Thanks for the report. Can you provide the output of the "Uno Platform" output as well ?

Thanks. Make sure to select a specific project in the project selector: https://platform.uno/docs/articles/get-started-vscode.html#prepare-the-webassembly-application

We're going to be releasing an update that makes step more obvious.

I couldn't do that, there isn't anything in the status bar to select. I did delete the webassembly project so that there was no other main project option just MyApp.Skia.Gtk and MyApp.Shared. I believe this is what made the "Multiple projects loaded, select one in OmniSharp" log message go away

Thanks. This likely means that the project fails to load in omnisharp. Can you take a look at the omnisharp log as well ?

So there was an exception there because MyApp-vsmac.slnf still referenced the missing Web Assembly project, I removed that now I get "MyApp-vsmac.slnf" selected but clicking it results in an error

Extension 'ms-dotnettools.csharp' CANNOT use API proposal: quickPickSeparators.
Its package.json#enabledApiProposals-property declares: [] but NOT quickPickSeparators.
 The missing proposal MUST be added and you must start in extension development mode or use the following command line switch: --enable-proposed-api ms-dotnettools.csharp

Why is there even a vsmac file here, is it confusing vscode?

@trampster

If I remove the vsmac file then it selects MyApp.sln, If I click that I get the same error.

I seem to be running into this error dotnet/vscode-csharp#4907

Some comments say fixing sln/csproj files can make it go away, others say even fresh templates from dotnet new cause this to happen.

Thanks, this looks like a recent issue in omnisharp: dotnet/vscode-csharp#4937.

You can try downgrading omnisharp to an earlier release, or upgrade to the preview.

I can confirm that upgrading to the OmniSharp beta fixes the problem
