Thought I solved this buy removing my folder and cloning a new copy, but the second the OmniSharp update you back to the error The terminal process failed to launch: Path to shell executable “dotnet” does not exist.

    Failed to load project file '{projectFilePath}'.
Microsoft.Build.Exceptions.InvalidProjectFileException: The SDK ‘Microsoft.NET.Sdk.Web’ specified could not be found.

I have downloaded an updated SDK
I changed the dotnet to a full path in tasks only to be presented with another error “” Project not found.
I have changed the omnisharp.path to latest, but this just install a beta version.

No idea what is going on here to be honest.

@Tynamix: Could you try setting the "omnisharp.path" option in the VS Code settings to "latest" and see if anything changes?

This issue sounds a lot like https://github.com/OmniSharp/omnisharp-vscode/issues/2330. In that issue, it seems like there is a difference between the PATH when launch VS Code via the macOS LaunchPad or by typing code at a Terminal window. In the latter case, C# for VS Code worked fine. Could you try that and let me know if this is the same behavior you’re seeing?
