NUnit3TestAdapter 3.15 OneTimeSetUp not working anymore

Visual Studio 2017 v15.9.14 <package id="NUnit" version="3.12.0" targetFramework="net471" /> <package id="NUnit3TestAdapter" version="3.15.0" targetFramework="net471" />

The first time I run a test, OneTimeSetUp is called, then every other runs fails. I had no problems with 3.14. I made a new project to reproduced it with minimal code and I can run multiple time my test and it always succeed with 3.14, but as soon as I upgrade to 3.15, it is never called anymore… If I restart VS, it work only once and all following try fails. Can be reproduced with nuget package or VS extension.

using NUnit.Framework;

namespace NunitAdapter315Bug
{
    [SetUpFixture]
    public class ProjectSetup
    {
        public static bool oneTimePassed = false;

        [OneTimeSetUp]
        public void OneSetup()
        {
            oneTimePassed = true;
        }
    }
}

using NUnit.Framework;

namespace NunitAdapter315Bug
{
    [TestFixture]
    public class TestNunitAdpaterTest
    {
        bool setupPassed = false;
       
        [SetUp]
        public void Setup()
        {
            setupPassed = true;
        }

        [Test]
        public void TestIt()
        {
            Assert.IsTrue(ProjectSetup.oneTimePassed);
            Assert.IsTrue(setupPassed);
        }
    }
}

If anyone else is having trouble downgrading to version 3.14 to avoid this bug, here are the steps I took:

1. Uninstall NUnit3TestAdapter from Visual Studio and make sure auto-update for your extensions are turned off.
2. Download the NUnit3TestAdapter-3.14.0.vsix file from the releases page here. (Under Assets)
3. Double click the .vsix file which will launch the VSIX Installer and install 3.14 on your desired version of visual studio.

It seems to work with my test solution, thanks
