It's only been 3 years since Visual Studio runs in 64-bit on x86 ;)
I think the biggest holdback for VS with ARM was there were no good build boxes out there. With VS for ARM, Microsoft released their own ARM dev kit hardware loaded with 32gigs of ram and a snapdragon 8cx. Anyone else selling ARM hardware for Windows skimps with like 4g of ram.
VS could however crosscompile to ARM32 and later ARM64 for quite awhile.
