title: Create custom user controls in wpf for reuse
body: <p>I was wondering how could I save a user control just like we can save a c# class in a dll file and import that file whenever we need to use that class. How could we import that control and use it. It will be nice if we could make custom controls and save them for reuse instead of having to copy the xaml and code behind every time we had to use it.</p>
