Extension no longer works....

[alexanderluiscampino]

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

was working couple days ago before the vscode update

I was told in a previous issue that this is fixed in a prerelease:

https://github.com/OmniSharp/omnisharp-vscode/releases/tag/v1.23.18-beta2

@PsychoNineSix Thank you. Possibly a stupid question, but how to enable the pre-release on vscode?

I had the same problem. Follow the instructions here: https://github.com/OmniSharp/omnisharp-vscode/wiki/Installing-Beta-Releases and then add "omnisharp.path": "latest" to your settings.json file.
