研究方向
The bug is in C# Interactive's object display. Look for how the REPL formats objects, likely in the Microsoft.CodeAnalysis.CSharp.Scripting or formatting components. Check files related to object formatting, perhaps in the InteractiveHost or similar. The issue is that abstract properties are printed twice, so investigate the property enumeration logic.
