Examine Method Foo.Bar() and see how and where it is referencing the Name
property of a FrameworkElement
, if that FrameworkElement
has a backing member (either a Property or a Field, possibly a Class) that member will (likely) have to be excluded from renaming obfuscation.
Also note that even once the exclusion is done (or if the member is excluded for other reasons), Dotfuscator will continue to warn.
