Lifetime problem with Xunit: InvalidOperationException: There is no currently active test.

[StefanBertels]

I get reproducable runtime error on one of two tests if I run all tests of the following test class / project. If I run just one test (e.g. manually in IDE Rider) everything looks good (no error).

Just guessing: maybe related to #657

Exception

System.InvalidOperationException: There is no currently active test.

System.InvalidOperationException
There is no currently active test.

Here is my C# project:

UnitTest1.cs

public class UnitTest1(Xunit.Abstractions.ITestOutputHelper testOutputHelper)
{
    [FsCheck.Xunit.Property]
    public void Test1()
    {
        testOutputHelper.WriteLine($"{nameof(Test1)}");
    }

    [Xunit.Fact]
    public void Test2()
    {
        testOutputHelper.WriteLine($"{nameof(Test2)}");
    }
}

TestProject1.csproj

<Project Sdk="Microsoft.NET.Sdk">
    <PropertyGroup>
        <TargetFramework>net8.0</TargetFramework>
        <IsTestProject>true</IsTestProject>
    </PropertyGroup>
    <ItemGroup>
        <PackageReference Include="FsCheck.Xunit" Version="3.0.0" />
        <PackageReference Include="Microsoft.NET.Test.Sdk" Version="17.12.0" />
        <PackageReference Include="xunit" Version="2.9.3" />
        <PackageReference Include="xunit.runner.visualstudio" Version="3.0.1" />
    </ItemGroup>
</Project>

Reproducable by just running dotnet test in project folder.

No error if I downgrade to xunit 2.8.1 / FsCheck.Xunit 2.16.6.
