    Update project: ElectronNet

Steps to reproduce

1. Load a folder that cointains a *.csproj file and *.cs files.
2. Open a *.cs file.
3. Display the intellisense menu by pressing ctrl + space.

Expected behavior

The intellisense menu shall show all available C# methods, properties, variables and so on.

Actual behavior

The intellisense menu shows only some “word completations”. It looks like the C# extension is not enabled. But the extension is working. There are syntax errors and so on shown.

@Patrick-vianexus , mine has stopped working and I’m now receiving this exact same message as you, even these GAC versions… unfortunately I’m in a rush now, but I’ll try to work around this later. Any news please let me know.

Cake is not related to the problem listed in this issue. Cake completion was indeed broken in OmniSharp 1.37.1 - it’s already fixed for the next release https://github.com/OmniSharp/omnisharp-roslyn/blob/master/CHANGELOG.md#1372---not-yet-released
