+## Windows Presentation Foundation
+
+There are two implementations of WPF, each with it's own documentation:
+
+01. The [.NET Framework 4 implementation](framework/wpf/index.md?view=netframeworkdesktop-4.8) that's supported by Visual Studio 2019 and Visual Studio 2017.
+
+    .NET Framework 4 is a Windows-only version of .NET and is considered a Windows Operating System component. This version of Windows Presentation Foundation is distributed with .NET Framework.
+
+    The documentation for this version of WPF is available [here](framework/wpf/index.md?view=netframeworkdesktop-4.8).
+
+01. The open-source implementation hosted on [GitHub](https://github.com/dotnet/wpf).
+
+    This version runs on **.NET 5 and .NET Core 3.1**. The WPF XAML Visual Designer requires, at a minimum, [Visual Studio 2019 version 16.X](https://visualstudio.microsoft.com/downloads/?utm_medium=microsoft&utm_source=docs.microsoft.com&utm_campaign=inline+link&utm_content=download+vs2019+desktopguide+winforms).
