The analyzer detected a possible error related to dependency property registration. The property that performs writing into/reading from properties was defined incorrectly.
class A : DependencyObject { public static readonly DependencyProperty CurrentTimeProperty = DependencyProperty.Register("CurrentTime", ....); public static readonly DependencyProperty OtherProperty = DependencyProperty.Register("Other", ....); public DateTime CurrentTime { get { return (DateTime)GetValue(CurrentTimeProperty); } set { SetValue(OtherProperty, value); } } } ....
Because of copy-paste, the methods GetValue and SetValue, used in the definitions of the get and set access methods of the CurrentTime property, work with different dependency properties. As a result, when reading from CurrentTime, the value will be retrieved from the CurrentTimeProperty dependency property, but when writing a value into CurrentTime, it will be written into 'OtherProperty'.
A correct way to address the dependency property in the code above is as follows:
public DateTime CurrentTime { get { return (DateTime)GetValue(CurrentTimeProperty); } set { SetValue(CurrentTimeProperty, value); } } }
