Microsoft .NET Desktop Runtime (x64) 8.0x — Overview and Description
Microsoft .NET Desktop Runtime (x64) 8.0x is the runtime component that enables Windows desktop applications built on .NET 8 to run on 64-bit Windows systems. It provides the core libraries, runtime services, and desktop-specific components required by Windows Forms and Windows Presentation Foundation (WPF) applications compiled for .NET 8. The runtime is distinct from the SDK: it contains only what’s needed to execute apps, not the developer tools for building them.
For Developers
