Pull Request Overview
This PR disables the automatically generated flow summary for System.ComponentModel.PropertyDescriptor.GetValue by adding a neutral model. The change prevents potential type safety issues where the method's object -> object signature could lead to incorrect upcasting and downcasting of known specific types to incompatible property types.
- Adds a manual neutral model for
PropertyDescriptor.GetValueto override the auto-generated flow summary - Removes the problematic
dfc-generatedflow summaries from test expectations for bothSystem.ComponentModel.PropertyDescriptorandNewtonsoft.Json.Linq.JPropertyDescriptor

This PR disables the flow-generated summary for
PropertyDescriptor.GetValue. The problem with this summary is that it has typeobject -> object, which means that we risk first upcasting a known specific typettoobject, and then subsequently downcasting it to a different type, which does not correspond to the type of any property oft.
