csproj (c#) project to project reference to fsproj (f#)

[mikehaas763]

Maybe this just is an incomplete part of the sdk as of right now. I have started from latest stable .net core (dotnet cli) 2.0.0. I've created a solution, then an f# lib project and a c# console app. They're both added to the solution. I then used the dotnet cli to add a project to project reference to my C# project, pointing to the F# project. However, I can't import the namespace in my C# file. It just can't find the F# namespace. Should this work?

Here's the contents of my csproj file:

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

  <ItemGroup>
    <ProjectReference Include="..\RxStore.Core\RxStore.Core.fsproj" />
  </ItemGroup>

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp2.0</TargetFramework>
  </PropertyGroup>

</Project>

This is dotnet/vscode-csharp#371.

@mikehaas763 To confirm what @DustinCampbell said, is this only happening to you in VS Code or also in Visual Studio? Does dotnet build on the command line succeed?

Just adding my two cents here, but I do face the same error.

@nguerrera Here is what works fine:

• Visual Studio 2017
• Visual Studio for Mac
• dotnet build

Only VS Code (Omnisharp) is having trouble loading the referenced F# project.

I am facing this issue with similar errors, when referencing a managed c++ vcxproj project.

[info]: OmniSharp.MSBuild.MSBuildProjectSystem
        Update project: CsProject
[info]: OmniSharp.MSBuild.MSBuildProjectSystem
        Found referenced project outside root directory: c:\tmp\cpt\vsCodeCppCs\CppProject\CPTCommon.vcxproj
[info]: OmniSharp.MSBuild.MSBuildProjectSystem
        Loading project: c:\tmp\cpt\vsCodeCppCs\CppProject\CPTCommon.vcxproj

It says: The type or namespace name 'xxx' could not be found (are you missing a using directive or an assembly reference?)
