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

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

        Suspend:       preemptive
        GC:            sgen (concurrent by default)

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 😃

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

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

@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
