.NET apps can now run natively on Windows ARM64. This follows the support we added for Linux ARM64 in .NET Core 3.0. With .NET 5.0, you can develop web and UI apps on Windows ARM64 devices, and deliver your applications to users who own Surface Pro X and similar devices. You can already run .NET Core and .NET Framework apps on Windows ARM64, but via x86 emulation. It’s workable, but native ARM64 execution has much better performance.
