Omnisharp-vscode: code completion not working

[marekw2143]

• VSCode Version: Code 1.18.1 (929bacba01ef658b873545e26034d1a8067445e9, 2017-11-16T18:34:22.110Z)
• OS Version: Linux x64 4.4.0-77-generic
• Extensions:

Extension|Author (truncated)|Version
---|---|---
vscode-nuget-package-manager|jmr|1.1.5
csharp|ms-|1.13.1
scorpio|whi|0.0.4

---

Steps to Reproduce:
With ASP .NET Core MVC application opened, try to use code-completion -it either waits very long with text "loading" . When run without extensions, code completion seems to suggest words which are present in currently opened file.

Doing "dotnet clean" followed by "dotnet build" does not solve the problem.

Reproduces without extensions: Yes

I recently got thesame problem but on windows. When i look in the Omnisharp Log i see error popping up like:

Assets file 'C:\Users\user\Documents\Visual Studio 2017\Projects\project\obj\project.assets.json' doesn't have a target for '.NETFramework,Version=v4.5.2/win7-x86'. Ensure that restore has run and that you have included 'net452' in the TargetFrameworks for your project. You may also need to include 'win7-x86' in your project's RuntimeIdentifiers.

FYI im using target win7-x64, though i have it not in the csproj-file like:
x64

Im specifying it when compiling like:
dotnet build project.csproj -r win7-x64

Vscode:
Version: 1.18.1
Architecture: x64

Dotnet --Info:

@marekw2143 : Could you provide your OmniSharp Log when loading your project in VS Code? To retrieve this, select View->Output from the VS Code menu and choose "OmniSharp Log" from the drop-down in the top-right corner of the Output pane.

@cwistedt : Given that you're on Windows, could you file a separate issue? The Windows and Linux implementations vary quite a bit, so the problem you're seeing is very likely different than what @marekw2143 has reported. Be sure to include your OmniSharp Log in the report.

Thanks @marekw2143. What Linux distro/version are you running? Also, could you let me know what version of Mono you have installed?

[marekw2143]

@DustinCampbell : Here's output of "mono --version":

And I'm on lubuntu 16.04

A couple of suggestions:

• Try updating to the latest mono-complete and msbuild packages.

• Try adding the following setting in VS Code:

  "omnisharp.path": "/home/marek/.vscode/extensions/ms-vscode.csharp-1.13.1/.omnisharp/run"

Thanks @DustinCampbell . previously "omnisharp.path" was set to "null", after changing it code completion works. Maybe upgrade from VSCode 1.17 to 1.18 overriden changes.
