C# Extension version: ms-vscode.csharp-1.15.2

Steps to reproduce

dotnet new webapi -o Teste.Api
dotnet new classlib -o Test.MyLib
dotnet add Teste.Api/Teste.Api.csproj reference Test.MyLib/Test.MyLib.csproj

Steps to reproduce (simplified)

dotnet new webapi
dotnet new classlib -o mylib
dotnet add reference mylib/mylib.csproj

Expected behavior

OmniSharp should load the project as normal and enable intellisense for classes inside Test.MyLib

I have verified that other issues with the same steps for execution also generates the same output, but in an earlier version, I was instructed to start a new issues, possibly the cause should be another #2286

Actual behavior

"dotnet run" works fine, but intelisense does not work, OminiSharp does not seem to work

Thanks for filing a separate issue. I have a couple of questions:

1. The OmniSharp Log above indicates that OmniSharp is using the MSBuild toolset from the VS 2017 Build Tools. Did you install the appropriate workloads into the VS 2017 Build Tools needed by your project (for example, correct version of .NET Framework, .NET Core, etc).

2. If the VS 2017 Build Tools are complete, could you try setting "omnisharp.path" to "latest" in the VS Code settings? This will cause C# to download and use a newer version of OmniSharp.

Thanks @DustinCampbell

I enabled Omnisharp for Debug mode and the output displayed the following error:

FAILURE: Could not locate 'C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\MSBuild\15.0\Bin\

I uninstalled Visual Studio 2017 and removed the folder, now OminiSharp is looking for buildtools in:

\User\.vscode\extensions\ms-vscode.csharp-1.15.2\.omnisharp\1.30.1-beta.63\msbuild\15.0\Bin\

Everything is working fine

Is there a place to manually set the path to look for buildtools at? I get this error if I have Visual Studio 2017 and VSCode 1.24.1 installed on the same machine.
