Omnisharp-roslyn: Omnisharp does not work with project that has reference

Created on 1 Aug 2018 · 18Comments · Source: OmniSharp/omnisharp-roslyn

Omnisharp does not work with project that has reference to another project.
For example I have two projects in a solution. One for code and One for unit test.
I add reference at test project. This is how test project .csproj file.

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>netcoreapp2.1</TargetFramework>

    <IsPackable>false</IsPackable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.7.0" />
    <PackageReference Include="xunit" Version="2.3.1" />
    <PackageReference Include="xunit.runner.visualstudio" Version="2.3.1" />
    <DotNetCliToolReference Include="dotnet-xunit" Version="2.3.1" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\ThaiNumber\ThaiNumber.csproj" />
  </ItemGroup>


</Project>

This is log message after I start Omnisharp.

I've come across this problem as well. I'm a vim user, so I rely on the http version of OmniSharp. Since 1) this is apparently fixed in the vscode extension and 2) the stacktrace mentions the Nuget.Common assembly I simply copied all Nuget.*.dll files from the vscode extension (~/.vscode/extensions/ms-vscode.csharp-1.17.1/.omnisharp/1.32.8/omnisharp) to the http version that is located under ~/.omnisharp/omnisharp-roslyn on my machine and now it works.

Some additional info:
I have the v1.32.1 release of omnisharp-roslyn installed (default version installed by omnisharp-vim at this moment).

I run omnisharp with a system-wide mono:

tmadsen@mini ~
❯ mono --version

and I have this dotnet core:

tmadsen@mini ~
❯ dotnet --version
2.2.101

In my eyes copy/pasting files around like that is not really a nice option, but I'm unsure at the moment where to fix this problem. Can someone point me in the right direction? Is it a source code issue where some project in the http-stack is referencing some nuget stuff different from the stdio-stack? (doesn't look like to me) or is some build-task that is copying files differently for stdio and http versions? If someone can point me in the right direction but doesn't have the time to fix it, I would be willing to try :)

What version of the .NET Core SDK are running? Could you provide the output of dotnet --info?

DustinCampbell on 2 Aug 2018

I'm having the exact same issue. Please see below for the output of dotnet --info

Note that I'm running omnisharp-roslyn 1.32.1 due to issue #1274 in latest.

Same issue for me, with similar output.

Downgrading msbuild from 15.8 back to 15.6 got it working again for me.

I was able to build the solution directly using msbuild 15.8 even when Omnisharp was failing to load it with the GetReferenceNearestTargetFrameworkTask failure errors.

Currently encountering this same error using VS Code. It was fine yesterday with no conscious software changes.

@rudism @FomTarro Can you set "omnisharp.loggingLevel": "debug" in VS Code's options and share you OmniSharp log?

@rudism @FomTarro Can you set "omnisharp.loggingLevel": "debug" in VS Code's options and share you OmniSharp log?

As additional info, I am using Unity version 2018.1. Haven't updated Unity since the spring, and as I said all was working fine last night.

Here's the full log, I think:

FomTarro on 11 Sep 2018

@FomTarro We believe we have identified the cause of the "GetReferenceNearestTargetFrameworkTask" issue and we've created a beta of the C# extension that includes the fix. Please install the beta VSIX (https://github.com/OmniSharp/omnisharp-vscode/releases/download/v1.16.1-beta1/csharp-1.16.1-beta1.vsix) and let us know if that resolves the problem

rchande on 12 Sep 2018

This solves the problem, yeah

FomTarro on 12 Sep 2018

I'm using omnisharp-vim (not vscode) which accesses the http version of omnisharp-roslyn, will the fix be applicable there as well?

rudism on 13 Sep 2018

@rchande, are you referring to a fix omnisharp-vscode? Please note that this is the issue tracking for omnisharp-roslyn and the original issue was reproduced through omnisharp-vim.

yufufi on 13 Sep 2018

@yufufi You want https://github.com/OmniSharp/omnisharp-roslyn/releases/tag/v1.32.5, which includes the fix we shipped in the C# Extension.

rchande on 13 Sep 2018

I believe this issue is fixed now--I'm going to close it, but feel free to keep discussing if you think it isn't.

rchande on 13 Sep 2018

Thanks @rchande. Unfortunately vim users on Mac/Linux are currently stuck on v1.32.1 due to #1274. And debugging/fixing #1274 is tricky because building on Linux doesn't work, see #1202. I've been waiting on a GitVersion fix, as @DustinCampbell suggested, not sure what more to do at this stage.

nickspoons on 13 Sep 2018

@nickspoons I left you a comment on #1202 -- basically, I would recommend disabling the GitVersion phase of the build so you're able to build/debug.

rchande on 14 Sep 2018

What are my options around #1258 & #1274? I am on Arch Linux with Vim

mysteryjeans on 4 Oct 2018

@mysteryjeans the latest OmniSharp-roslyn _release_ which works with vim is 1.32.1 - install this version in vim (using the latest OmniSharp-vim) by runnig :OmniSharpInstall 'v1.32.1' (in fact currently you only need to do :OmniSharpInstall - we've set the default to v1.32.1 until #1274 is resolved).

However, I believe it's a problem with the releases that is causing the HTTP connection issues seen in #1274, not the code. Building your own OmniSharp-roslyn should let you use the latest version from vim.

Unfortunately, building is also not straightforward at the moment, due to #1202. I did manage it on an Arch Linux system eventually, see my steps here

nickspoons on 4 Oct 2018

Some additional info:
I have the v1.32.1 release of omnisharp-roslyn installed (default version installed by omnisharp-vim at this moment).

I run omnisharp with a system-wide mono:

All my problems were solved by installing msbuild, which wrongly I assumed was installed via mono-complete

sudo dnf install msbuild

" C#
let g:OmniSharp_highlight_types = 1
let g:OmniSharp_proc_debug = 1
let g:OmniSharp_loglevel = 'debug'

Once msbuild is installed, following the prompt to install rosyln, the debug logs showed a happy Omni-vim
