V3047. WPF: A class containing registered property does not correspond with a type that is passed as the ownerType.type.

Jan 19 2016

The analyzer detected a potential error related to dependency property registration. When registering a dependency property, the owner type specified for this property refers to a class different from the one the property is originally defined in.

class A : DependencyObject { .... }
class B : DependencyObject
{
public static readonly DependencyProperty CurrentTimeProperty =
  DependencyProperty.Register("CurrentTime", typeof(DateTime),
                              typeof(A));                     
....

Because of using copy-paste when registering the dependency property, class 'A' was mistakenly specified as its owner while this property was actually defined in class 'B'.

A correct way to register this dependency property is as follows:

class B : DependencyObject
{
public static readonly DependencyProperty CurrentTimeProperty =
  DependencyProperty.Register("CurrentTime", typeof(DateTime),
                              typeof(B));
