NuExt.DevExpress.Mvvm 0.7.1

NuExt.DevExpress.Mvvm

NuExt.DevExpress.Mvvm is a NuGet package that offers a suite of extensions and utilities for the DevExpress MVVM Framework. The focus of this package is on asynchronous operations, enhancing the core capabilities of the DevExpress MVVM framework and simplifying the implementation of the Model-View-ViewModel (MVVM) pattern in WPF applications. It provides developers with tools to efficiently handle async tasks, improve application responsiveness, and reduce routine work.

Migration Note

If you are starting a new project or planning to modernize an existing one, consider using the NuExt.Minimal.Mvvm family instead of this package.

NuExt.Minimal.Mvvm, NuExt.Minimal.Behaviors.Wpf, and NuExt.Minimal.Mvvm.Wpf provide a more streamlined and predictable MVVM model with:

• a minimal and dependency‑free core,
• deterministic async command semantics,
• lightweight ViewModel lifecycles,
• explicit view/document/dialog composition,
• clean integration with modern .NET and multi‑UI‑thread WPF scenarios.

This package remains functional and stable for existing applications, but the Minimal.Mvvm stack is recommended for new development due to its clearer architecture, smaller surface area, and async‑first design.
