Model View View Model (MVVM) classes with built in Dependency Injection (DI) for all variants of .NET.

Also provides centralised multi-platform UI Management for WPF (.NET Framework, .NET Core 3.1 and .NET 5.x) and WinUI 3 (Preview 4 and above)(Experimental)


  • Implements INotifyPropertyChanged
  • Implements INotifyDataErrorInfo
  • Events for handling and detecting changes
  • Additional properties for
    • IsLoaded
    • IsBusy
    • IsBusyReveresed
    • IsValid
    • IsEditable
    • IsEditableReversed
  • Data Validation
  • Built-In Error notification methods
  • ICommand binding helpers
  • Notification extension actions
    • Rather than overriding a property, add an action when it changes
  • Base View Models for
    • Forms
    • Lists
    • Searchable Lists
    • Tree View Searchable Lists
  • UI
    • Core UI functions for Showing Alerts and Confirmation Dialogs (using platform specific implementations)
      • UWP, WinUI and WPF (.NET Framework and .NET Core 3.1, .NET 5+)



This is the base View Model abstract class which contains the most common MVVM functionality


This class inherits from ViewModel and provides additonal functionality for managing lists of data

SearchViewModel<T, T2>

This class inherits from ListViewModel<T,T2> and adds search and filtering functionality to the standard ListViewModel

SearchTreeViewModel<T, T2>

This class inherits from SearchViewModel<T, List<T>> and adds Tree Path preparation to the standard SearchViewModel

Using System.Mvvm

Basic ViewModel

All of the ViewModel base classess are in the System.Mvvm namespace. To create a basic ViewModel simple inherit from ViewModel.

using System.Mvvm;
public class MainViewModel : ViewModel

To create a notifiable property create a property with a backing field using the propfull snippet and add a call to NotifyPropertyChanged.

private int myVar;

public int MyProperty
    get { return myVar; }
    set { myVar = value;  NotifyPropertyChanged();}

NotifyPropertyChanged will automatically pickup the calling member, but you can also be explicit.

private int myVar;

public int MyProperty
    get { return myVar; }
    set { myVar = value; NotifyPropertyChanged(nameof(MyProperty)); }

Using System.Mvvm.Ui

The UI static class provides two features

  • A central interface for calling some simple UI functions
    • ShowAlert(string title, string message)
      • Show an alert with a title and message
    • ShowConfirmation(string title, string message)
      • Show a confirmation dialog and return the result
    • InvokeOnUIThread(Action)
      • Execute the action on the UI thread
    • InvokeOnUIThreadAsync(Action)
      • Execute the action on the UI thread asyncronously

The standard UI functions can be called directly after adding the DSoft.Mvvm.Ui package

using System.Mvvm;

var result = await UI.ShowConfirmationDialogAsync("Confirm this", "This is a platform specific confirmation message");

if (result)
    await UI.ShowAlertAsync("YAY!", "You confirmed that");

NOTE: The standard UI functions only work when the platform code has been registered using MvvmManager.Init on the supported plaforms


MvvmManager is a class that is found in the Dsoft.System.Mvvm.Ui package and registers the standard UI implementation for UI for each supported platform.

Call MvvmManager.Initto initialise the platform implementation.

NOTE: Only WPF(.NET framework, .NET Core 3.1, .NET 5.x) and WinUI 3 (Preview 4 and above) and UWP are supported with MvvmManager at the moment
