## What it is
Windows Driver Frameworks (WDF) is Microsoft's open-source framework of libraries for writing high-quality Windows device drivers, including the source behind KMDF and UMDF v2. It enables developers to read framework internals and perform step-through debugging of drivers against the actual source.

## Use cases
- write a Windows device driver
- debug a kernel-mode driver with framework source
- understand what a WDF API does internally
- analyze driver crash dump files
- develop a UMDF v2 user-mode driver

## When to choose
- you are developing Windows drivers with KMDF or UMDF v2 and want source-level transparency
- you need to step through framework code while debugging a driver
- you want to diagnose driver crashes by inspecting framework internals

## When to avoid
- you are writing drivers for Linux or macOS
- you need a stable API contract and cannot tolerate undocumented behavior that may change
- you only need driver samples rather than the framework source

## Facets
- artifact type: library
- maturity: maintenance
- function: sdk, developer-tools
- domain: operating-systems, developer-tools, hardware
- platform: windows, cpp, c
- tags: windows-drivers, kmdf, umdf, kernel-development, device-drivers
