Gets a value that indicates whether this XamlMember represents a member that has a callable public set accessor.
Assembly: System.Xaml (in System.Xaml.dll)
Calling invokes LookupIsWritePublic or a specific override of that method.
The LookupIsWritePublic method is virtual and therefore, can be overridden. The override has the potential to change (maliciously or otherwise) the reported access information of a XAML member so that it no longer aligns in an expected way with the type system access information of its underlying CLR declaration. For any security-critical checks of access levels, use the underlying CLR type instead.
