Sure, and that's why a good number of UWP apps have ARM64 versions. But UWP apps represent a miniscule fraction of the .NET Windows apps out there. What makes it even smaller is the fact that .NET Native is even a subset of .NET Standard, so some things like Reflection don't work without some additional tweaking. Can you write a UWP app using .NET that runs on ARM64? Sure! But basically every non-UWP Windows .NET app needs to wait for .NET 5 to build for ARM64.
