MaterialDesignStepNumberIconTemplate not found

I am trying to use stepper but it always shows this error
System.Windows.ResourceReferenceKeyNotFoundException: ''MaterialDesignStepNumberIconTemplate' resource not found.'

what is that?

I figured it out.
you need to mention in the documentation that we need add Generic.xaml dictionary .
please feel free to close this issue
