Cannot find element for dotnet test id: error in Resharper 2016.3

Question

I just downloaded Resharper 2016.3 EAP 4 to check out the Unit test functionality with .NET Core. But when I run all unit tests, I get this error:

Cannot find element for dotnet test id: MvcMovieTests.SimpleTests.TestMethodPassing

Cannot find element for dotnet test id: MvcMovieTests.SimpleTests.TestMethodFailing

Here are my simple unit tests:

[TestClass]
public class SimpleTests
{
    [TestMethod]
    public void TestMethodPassing()
    {
        Microsoft.VisualStudio.TestTools.UnitTesting.Assert.IsTrue(true);
    }

    [TestMethod]
    public void TestMethodFailing()
    {
        Microsoft.VisualStudio.TestTools.UnitTesting.Assert.IsTrue(false);
    }
}

When I run all unit tests with the MSTEST Test Explorer, they run properly and I see the results. But with Resharper 2016.3 I get the two errors above showing up in the Unit Test Sessions window in Visual Studio 2015 Community.

Clearing up the ReSharper caches fixed it up for me. Open the Environment | General page of ReSharper options. Click Clear caches. More information here.
