Paulo -- I'm a bit confused. VS Code doesn't launch MSBuild to build your project. Also, your repro steps don't actually get to the actual behavior (I assume you've opened the project and built somehow). Could you clarify your steps?

[paulomorgado]

@DustinCampbell,

I created a solution on Visual Studio 2017 RC with a class library project and a XUnit unit test project.

Then I opened it in VSCode (after installing the latest beta of OmniSharp - 1.6.0-beta6).

Then I pressed Ctrl+Shift+B to build and it prompted me to configure the task runner and I chose MSBUILD.

The solution is here, if you want to take a look at it.

[DustinCampbell]

Ah. The problem is choosing MSBuild. That's not actually owned by the C# extension. Try this:

1. Delete the .vscode folder in your project.
2. Open the project in VS Code.
3. Press Ctrl+Shift+B and choose ".NET Core"

[paulomorgado]

Doh!

Now it builds using Microsoft (R) Build Engine version 15.1.458.808.

Can I run the unit tests in VSCode?

[DustinCampbell]

Not really. We don't have very robust support for unit testing in VS Code. There's some support, but it's not great. You should be able to run unit tests at the command line with dotnet test.

[paulomorgado]

Yep! Working fine on the command line.

Strange that the test project builds fine, but on the editor it's complaining about Moq.

[DustinCampbell]

Maybe run dotnet restore at the command line?

[paulomorgado]

That was my first thought.

Eventually closing and opening VSCode solved it.

[DustinCampbell]

Ahh... it's likely that you had VS Code open with your project when you performed a dotnet restore. In that case, OmniSharp wouldn't have caught the change yet. You can kick OmniSharp with the Restart OmniSharp command inside VS Code (or close/open your project, or just restart).

csproj-based .NET Core projects are still a work-in-progress. :smile:

[DustinCampbell]

Paulo, I'm going to close this for now because the original issue sounds like it's solved. Feel free to file issues if you come across problems. We're definitely interested in whatever can help make the extension better. Thanks!

can anyone help me with this
thankyou

[DustinCampbell]

@SonaliRane26: This is the repo for the C# extension for VS Code. We can only help you here with issues related to that project.

I suspect you're looking for https://github.com/dotnet/cli or https://github.com/dotnet/sdk. However, I can tell you that you will not be able to build Xamarin or Portable projects with the .NET CLI, which it looks like you're trying to do.

[SonaliRane26]

Yes, thankyou
