How to get the current lifetime scope type in InitializeAsync

[TheRumle]

It would be very helpful to have access to the current SharedType of a data source. Here is an illustrative example:

public class MyDataSource : IAsyncInitializer
{
    public int MyData { get; private set; } = -1;
    public Task InitializeAsync()
    {
        // get the current sharedtype for SharedDataSource. 
        var myKey = TestContext.Current.DataSource.SharedType;
        MyData = await DataGetter.GetKeyedAsync(myKey);
        return Task.CompletedTask;
    }
}

In the above snippet, I want to know the lifetime scope of MyDataSource at initialization time. I imagine maybe a field TestContext.Current.DataSource.SharedType and TestContext.Current.DataSource.Key.

For instance, I would expect the following

public class MyTest
{
    [Test]
    [ClassDataSource<MyDataSource>(Shared = SharedType.Keyed,Key = "HelloWorld")]
    public void KeyedTest(MyDataSource keyedFixture)
    {
        //in this test DataGetter.GetKeyed is called with (Keyed, String)
    }
    
        
    [Test]
    [ClassDataSource<MyDataSource>(Shared = SharedType.PerTestSession)]
    public void PerTestSessionTest(MyDataSource keyedFixture)
    {
        //in this test DataGetter.GetKeyed is called with PerTestSession
    }
}

@TheRumle upgrade to the latest and you can do:

if (TestContext.Current?.Metadata.MethodDataSource is ClassDataSourceAttribute<MyFixture> attr)
{
    var shared = attr.Shared; // SharedType.Keyed
    var key = attr.Key;       // "MyKey"
}
