.NET Core 2.0 xUnit tests not discovered in VSTS

Question

Im trying to set up VSTS Continuous Integration with a .NET Core 2.0 project and xUnit.

I've got the xunit.runner.visualstudio NuGet package installed, and everything works fine in Visual Studio.

VSTS cant find any tests to run though.

What I could find so far is this article, which describes how to set it up with .NET Core 1.0, by using project.json. Unfortunately that wont work, because project.json is gone in .NET Core 2.0.

Any suggestions?

VSTS output:

You need to specify vstest.console.exe in IED\Extensions\TestPlatform folder and framework options in Visual Studio Test task:
