Source generator doesn't see DefaultMemberAttribute

[jkurdek]

When working with source generators we encountered the following:

public class C
{
    [IndexerName("MyIndexer")]   
    public int this[int x]
    {
        get => 1;
        set { }
    }
}

This generates DefaultMemberAttribute(MyIndexer) on class C. However, when inspecting properties of C from within transform function of IncrementalSourceGenerator this information is not available.
