Project setup

I created a new solution with a class library (using .NET 8.0.401) using TUnit 0.1.783 (but have also tried on 0.1.752):

<Project Sdk="Microsoft.NET.Sdk">

    <PropertyGroup>
        <TargetFramework>net8.0</TargetFramework>
        <ImplicitUsings>enable</ImplicitUsings>
        <Nullable>enable</Nullable>
    </PropertyGroup>

    <ItemGroup>
      <PackageReference Include="TUnit" Version="0.1.783" />
    </ItemGroup>

</Project>

Then I created the following class:

public class ExampleTests
{
    [Test]
    public async Task Sample()
    {
        bool actual = true;
        await Assert.That(actual).IsTrue();
    }
}

Running it via dotnet test appears to work:

But the tests are not being discovered. I've already checked "Enable Testing Platform", and I've downgraded Rider to 2024.2.4, but hasn't worked.
