Research direction
Investigate RetargetingEventSymbol.GetAttributes method in Roslyn's C# compiler source (likely in src/Compilers/CSharp/Portable/Symbols/Retargeting/RetargetingEventSymbol.cs). The issue states it fails to retarget attributes from the underlying event. Also examine the equivalent Visual Basic implementation for guidance, as the issue notes to check VB's implementation. Look for how the underlying event's attributes are accessed and ensure they are properly mapped during retargeting.
