Unity + VScode + Omnisharp + Mac not working

[HawkenKing]

Intellisense keeps rebuilding as you type. It's broken.

From the plugin docs:

However, support for Unity and Xamarin, and other .csproj-based projects has been temporarily disabled for OS X and Linux. Rest assured that this will be restored in the near future!

In the meantime, you can install and use this the Legacy OmniSharp extension to enjoy a great C# editing experience on OS X and Linux for .csproj-based projects, such as Unity and Xamarin.

Sadly this is not true! On Mac and it keeps rebuilding as you type.

Can't downgrade VScode to 0.10.3 (omnisharp works on this version) as this version has a bug where auto update can't be turned off, so it just reinstalls to the latest version again.

This is a bug in both "Legacy C# support" and "C#" plugins on mac.

Please you're our only hope on mac...

@HawkenKing, the plugin doc text you provided is out-of-date, could you link to it so I can update it?

The latest C# extension (1.3) does work on OS X with Unity, though there are some known issues with larger projects. Could you clarify?

[HawkenKing]

Hi thanks for the reply.

The plugin text quote above is from the about page for "Legacy OmniSharp Support for Visual Studio Code" version 0.3.3 (select extension in extensions panel)

The exact problem is best shown in this gif. Have tried this on all three of my macs, same problem.

See how the "references" text disappears then rebuilds? Happens about every 5 seconds while typing, both "Legacy C# support" and "C#" plugins on mac.

[HawkenKing]

Also I get this error when using "C#" plugin on mac.

@HawkenKing are you trying to do .NET Core debugging? If not, you kind ignore that failure if you like, though we can try and help you if you are interested.

If you would like help -- please open a new bug and include your version of the C# extension and your version of .NET CLI (dotnet --info).

[DustinCampbell]

@HawkenKing: Also, the "Legacy OmniSharp Support for Visual Studio Code" extension is quite old. I'd recommend uninstalling it and only using the C# extension.

[HawkenKing]

@DustinCampbell The above GIF was screen recorded using the C# extension, I uninstalled the legacy one a while back.

[HawkenKing]

@gregg-miskelly nope! VScode alerts obscure the tabs area so would be nice to know how to get rid of it though...

[gregg-miskelly]

@HawkenKing please open a new bug then for your debugger install issue. Please include the version of the .NET CLI which you have installed (dotnet --info).

@HawkenKing: Could you provide your OmniSharp log? You can find this by select View->Output from the menu and then choosing "OmniSharp Log" from the drop-down on the right-hand side:

[Xelnath]

This happens when I try to mouse-over or inspect class or instance variables.

[DustinCampbell]

I believe that all of these issues should be addressed in the latest release of the extension (1.5.2).
