Answer 1

xmlns:c="clr-namespace:Converters"
You should check the namespace of your Converters class, that is what you should put in place of Converters. If Converters is your class, then you should put whatever it says after namespace in your .cs file.
Example:
namepsace MyNamespace {
public class Converters { }
}
Then your XAML would be:
xmlns:c="clr-namespace:MyNamespace"
Extra:
If you want to be more specific, you can add the assembly parameter as well.
xmlns:window="clr-namespace:MyNamespace;assembly=MyNamespace"
Where Assembly can be found in your Build Properties (Right-click Project, Properties, Application, Assembly Information)
Your default namespace can also be found in the Build Properties as well.
