In 2005 Microsoft introduced MVVM as a software architectural pattern to support the development of XAML apps, originally in WPF and later also in Silverlight.

In 2021 the Microsoft.Toolkit.Mvvm package is a modern, fast, and modular .NET Standard MVVM library that runs on any app platform (UWP, WinForms, WPF, MAUI, Uno, and WinUI) and on any runtime (.NET Native, .NET Core, .NET Framework, and Mono) with an API surface that is the same in all these environments.
