Installation

dotnet add package Frank.Wpf.Hosting

Usage

using Frank.Wpf.Hosting;

public static class Program
{
 [STAThread] // Required for WPF
 public static void Main()
 {
 var builder = Host.CreateWpfHostBuilder(); // Create a WPF host builder
 builder.Services.AddTransient<IMyService, MyService>(); // Register services
 var host = builder.Build<MyWindow>(); // Create the host with the window inheriting from MainWindow
 host.Run(); // Start the application and show the window
 }
}

To get this point you need to create a window that inherits from MainWindow:

using Frank.Wpf.Hosting;

public class MyWindow : MainWindow
{
 public MyWindow(IMyService myService)
 {
 // Use the service
 }
}

Advanced usage

If you want to have multiple windows, and not just dialogs, you can use the IWindowFactory interface:

using Frank.Wpf.Hosting;

public class MyService : IMyService
{
 private readonly IWindowFactory _windowFactory;

 public MyService(IWindowFactory windowFactory)
 {
 _windowFactory = windowFactory;
 }

 public void DoSomething()
 {
 _windowFactory.CreateWindow<OtherWindow>(true); // Create a new window and show it (true)
 }
}

You can also get the window by name using the IWindowFactory interface:

using Frank.Wpf.Hosting;

public class MyService : IMyService
{
 private readonly IWindowFactory _windowFactory;

 public MyService(IWindowFactory windowFactory)
 {
 _windowFactory = windowFactory;
 }

 public void DoSomething()
 {
 _windowFactory.CreateWindow("DisplayWindow", true); // Create a new window and show it (true)
 }
}

Note: The window name is the actual property name of the window, not the class name.

If you want to share data between windows, you can use the IApplicationCache interface, and access it using the Dispatcher directly when needed:

using Frank.Wpf.Hosting;

public class DisplayWindow : Window
{
 private readonly IApplicationCache _cache;
 private readonly Label _label;
 private readonly Timer _timer;
 
 public DisplayWindow(IApplicationCache cache)
 {
 _cache = cache;
 Title = "Hello, World!";
 Name = "DisplayWindow";
 Width = 800;
 Height = 600;
 
 _label = new Label
 {
 Content = "Hello, World!"
 };
 
 Content = _label;
 
 _timer = new Timer(1000);
 _timer.Elapsed += (_, _) => UpdateLabel();
 _timer.Start();
 }

 private void UpdateLabel() => Dispatcher.Invoke(() => _label.Content = _cache.Get<string>("message")); // Access the cache using the Dispatcher because the timer runs on a different thread
}

public class InputWindow : Window
{
 private readonly IApplicationCache _cache;
 private readonly TextBox _textBox;
 
 public InputWindow(IApplicationCache cache)
 {
 _cache = cache;
 Title = "Hello, World!";
 Width = 800;
 Height = 600;
 
 _textBox = new TextBox();
 
 var button = new Button
 {
 Content = "Set message"
 };
 
 button.Click += (sender, args) => _cache.Set("message", _textBox.Text);
 
 Content = new StackPanel
 {
 Children =
 {
 _textBox,
 button
 }
 };
 }
}
