Developer Tooling

Software Development Kit

A software development kit packages tools, libraries, and interfaces for building against a platform or service. It can include compilers, API clients, headers, and examples; SDK versions may affect both build compatibility and runtime behavior.

Also known as: SDK

Why it matters

Versioned development interfaces affect which targets can be built and supported.

Practical example

Pin the platform SDK version when a build must match a specific deployment target.
