Official binaries of Microsoft Direct3D 12 for Linux extracted from Windows Subsystem for Linux 2 (WSL 2).
Some people ask me why contains 10.0.20277.1 version's binary.
Because this is the last version for Windows Iron branch which have both arm64 and x64 version. Also, I had calculated the SHA-256 between related x64 files from 20277.1 and related files from Windows Server 2022 ISOs before 20348.1970, and the results are the same.
