how to use it with DependencyInjection

Describe the bug

I am very interested in this WPF framework and hope to incorporate it into my project. However, my project has already taken shape, and I am using the Microsoft.Extensions.DependencyInjection DI framework, and have rewritten the constructor of MainWindow. In this case, when I tried the methods described in the Getting Started documentation, the framework did not take effect, and I did not find any relevant documentation that could solve my problem. What should I do?

Additional context

Start with the Getting Started documentation and the MainWindow constructor used with Microsoft.Extensions.DependencyInjection. Determine how WPF-UI should be integrated in that setup; done means the documentation explains the required .NET 8/WPF integration clearly enough for a reader to apply it without guesswork.
