Agree it's not a bug as I assume it's an implementation of the IValueConverter interface: https://docs.microsoft.com/en-us/dotnet/api/system.windows.data.ivalueconverter?view=netframework-4.7.2 https://docs.microsoft.com/en-us/dotnet/api/system.windows.d... However since the method bodies are identical, IMO one should have the full implementation and then the other should just call the first. Still not a bug, just a code smell.
