# .NET 11 raises processor requirements in release-candidate documentation

_Published Tuesday, November 10, 2026 at 9:24 AM EST · Infrastructure · Latest · Tier 2 — Notable_

Microsoft's .NET 11 runtime documentation, updated for release candidate 2, raises the minimum x86/x64 processor baseline from x86-64-v1 to x86-64-v2 across Apple, Linux and Windows. Applications will fail to run on processors missing the required instructions.

Windows Arm64 systems must also support the LSE instruction set; minimum Arm64 hardware requirements remain unchanged on Apple and Linux. Updated ReadyToRun compilation targets can add startup overhead on supported machines lacking the targeted instructions. Microsoft says the changes reduce maintenance complexity and better align the runtime with operating-system hardware requirements.
