RegreTTO avatar Feb 13 '24 17:02 RegreTTO

@RegreTTO please make sure you have all the latest versions of the extension and Avalonia. If the issue persistets file a minimum repo.

Note: that the extension has its own repo where issues should be reported.

timunie avatar Feb 13 '24 18:02 timunie

@RegreTTO This is fixed in the version v0.0.30, could you confirm that you have latest version of the extension?

prashantvc avatar Feb 14 '24 06:02 prashantvc

@prashantvc Yes. I've checked the version right now and it is exactly v0.0.30

RegreTTO avatar Feb 14 '24 14:02 RegreTTO

@timunie It was the first time I installed all avalonia-related plugins, so they are exactly last version

RegreTTO avatar Feb 14 '24 15:02 RegreTTO

11.0.6 is outdated. 11.0.9 is recent.

timunie avatar Feb 14 '24 15:02 timunie

I installed it as said in the docs with dotnet new install Avalonia.Templates. I took version from my .csproj file.

RegreTTO avatar Feb 14 '24 15:02 RegreTTO

The templates were maybe not updated yet. They are not always in sync with latest minor version, so please try to update your nugets 🙏

timunie avatar Feb 15 '24 07:02 timunie

@timunie Hello! How can I update my nugets? I tried

dotnet new install Avalonia.Templates::11.0.9

I got

Warning: Avalonia.Templates::11.0.9 is not found in NuGet feeds https://api.nuget.org/v3/index.json. Avalonia.Templates::11.0.9 could not be installed, the package does not exist.

I also searched for the Avalonia.Templates and found that the latest version is 11.0.6. https://www.nuget.org/packages?q=Avalonia.Templates

calee88 avatar Feb 17 '24 01:02 calee88

I tried to update the package versions by manually changing the versions in .csproj file, and rebuild the project. However, the problem persists.

calee88 avatar Feb 17 '24 01:02 calee88

I changed the extension to v0.0.29, and the problem has been resolved.

calee88 avatar Feb 17 '24 01:02 calee88

Thanks, I'll try downgrading later

RegreTTO avatar Feb 17 '24 16:02 RegreTTO

@calee88 Indeed, downgrading fixes this problem

RegreTTO avatar Feb 18 '24 08:02 RegreTTO

Or not. After rebooting it started to infinitely ask me to build project, but nothing changes. It asks, I build, it asks again and so on

RegreTTO avatar Feb 18 '24 10:02 RegreTTO

@RegreTTO please upload a minimum sample for us to reproduce.

timunie avatar Feb 18 '24 10:02 timunie

@timunie There is no need me to upload such. It is just dotnet new avalonia.mvvm, nothing more

RegreTTO avatar Feb 18 '24 10:02 RegreTTO

I'm having the same issue 😓

microhobby avatar Feb 27 '24 00:02 microhobby

Interesting, if I downgrade the extension to the v0.0.29 it works 🤔

Edit: yeah, now I see that this was already proposed, then confirmed.

microhobby avatar Feb 27 '24 00:02 microhobby

I can confirm. Just follow Avalonia docs to reproduce this error. Avalonia.Templates::11.0.6 is the newest version available.

Might be related to this OmniSharp issue #2525 or #2550

I have the same problem, even after updating all the Avalonia packages in my project to 11.0.9 and with extension v0.0.31.

I'm running VS Code on Windows but connected to WSL.

doxxx avatar Mar 05 '24 20:03 doxxx

However, the same happens for a project opened from the Windows filesystem.

doxxx avatar Mar 05 '24 20:03 doxxx

@doxxx the WSL support is untested. Let me check this one windows

prashantvc avatar Mar 28 '24 08:03 prashantvc

I changed the extension to v0.0.29, and the problem has been resolved.

Same issue here. Installed the latest versions of Avalonia.Templates which is 11.0.11 at the time of writing and the Avalonia VS Code Extension in version 0.0.31. Downgraded to 0.0.29 resolved the issue.

I am working on Pop!OS Linux by System76. VS Code is installed via flatpak.

Steps to reproduce:

  • Install .NET 8 SDK
  • Install VS Code from Flatpak (latest version)
  • Install the Avalonia VS Code Extension (0.0.31 in my case, or 0.0.30 as stated in the comments above)
  • Install Avalonia.Templates
  • Create new MVVM Project dotnet new avalonia.mvvm
  • Open up the MainWindow.axaml file
  • Type a < somewhere in the document
  • Error message will pop up:

If this helps anyone, 0.0.31 had issues. Downgrading to 0.0.29 resolved the issue.

Can confirm that the issue is fixed in latest commits. But you have to build the latest AvaloniaLSP manually.
