## What it is
GongSolutions.WPF.DragDrop is an easy-to-use drag-and-drop framework for WPF applications, distributed via NuGet. It supports MVVM through attached properties, multiple selection, reordering, cross-control dragging, and visual adorners across ItemsControls like ListBox, ListView, TreeView, and DataGrid.

## Use cases
- add drag and drop to a WPF ListBox with MVVM
- reorder items in a WPF ListView by dragging
- drag items between two WPF TreeViews
- implement drag-drop handlers in a ViewModel without code-behind
- show drag preview adorners in a WPF DataGrid
- support multi-select drag and drop in WPF

## When to choose
- building WPF desktop apps on .NET Framework 4.6.2+ or .NET 6+ on Windows
- you want MVVM-friendly drag-and-drop with no code-behind
- you need drag-and-drop across standard ItemsControls with sensible defaults

## When to avoid
- developing for non-Windows platforms like Avalonia, MAUI, or WinUI
- you need drag-and-drop in web or non-.NET applications
- your project targets WPF versions older than .NET Framework 4.6.2
