If every developer had to write their own code for every basic function, software development would be incredibly slow. Instead, they use Microsoft's libraries. The is simply a package that contains these standard library files (DLLs).
Microsoft creates "binary compatible" updates between certain versions. This means the libraries for 2015, 2017, 2019, and 2022 are designed to be compatible with one another.
The runtime supports multiple hardware frameworks. System administrators must deploy the specific variant matching the target application architecture, not just the operating system architecture. Architecture Target Hardware Deployment Use Case 32-bit Intel/AMD processors Legacy software, 32-bit applications on 64-bit OS X64 64-bit Intel/AMD processors Standard modern 64-bit desktop software and games ARM64 ARM-based Windows devices SnapDragon/Qualcomm powered Windows laptops
But the 2019 version is particularly stable. It bridges older Windows 7/8.1 systems and modern Windows 10/11, making it a default choice for cross-version compatibility.
