title: Dependency Injection in .NET Core 3.0 for WPF
body: <p>I’m quite familiar with ASP.NET Core and the support for dependency injection out of the box.  Controllers can require dependencies by adding a parameter in their constructor.  How can dependencies be achieved in WPF UserControls?   I tried adding a parameter to the constructor, but that didn’t work.   I love the IOC concept and would prefer to bring this forward to WPF.  </p>
