PsdUtilities.ModularWpf

ModularWpf is based off the CommunityToolkit.Mvvm package, a utility library that helps with modulation seperate parts of the WPF application.

Features

• IServiceCollection extensions that help with registering common models of the MVVM pattern: AddView<TView, TViewModel>(), AddCachedView<TView, TViewModel>(), AddViewModel<TViewModel>()
• Modular Windows - you can assign a Window object with a IModularWindow interface, then await the window and get the result via the service

How to use

First lets define our window object:

public sealed partial class MyModularWindow : Window, IModularWindow
{
	public MyModularWindow()
	{
		InitializeComponent();
	}
}

Now lets register the window and the service

myServiceCollection.AddModularWindow<MyModularWindow>();
myServiceCollection.AddModularWindowsService();

// OR if you dont want to register each window manually:
myServiceCollection.AddModularWindows(assemblyFilter: a => a == typeof(MyModularWindow).Assembly)); // ! automatically registers the service as well !

Use-case

public sealed partial class MyViewModel : ObservableObject
{
	private readonly IModularWindowsService _modularWindowsService;

	public MyViewModel(IModularWindowsService modularWindowsService)
	{
		_modularWindowsService = modularWindowsService;
	}

	[RelayCommand]
	private async Task OpenMyWindowAsync()
	{
		await _modularWindowsService.ShowWindowAsync<MyModularWindow>();
	}

	[RelayCommand]
	private async Task OpenMyWindowWithResultAsync()
	{
		// string is a result type that is defined in the IModularWindow<TResult> interface
		// regular IModularWindow doesnt have a return type, so in the implementation just keep it with the NotImplementedException
		var result = await _modularWindowsService.ShowWindowAsync<MyModularWindow, string>(); 
		Console.WriteLine(result);
	}
}
