## Description

The Windows App SDK is a set of APIs and UI frameworks for building native Windows desktop applications. It provides a Windows Runtime API for accessing system capabilities and a dedicated UI framework for creating responsive, accessible interfaces. The project also functions as a desktop app deployment framework and a local AI execution environment for running hardware-accelerated models on CPUs, GPUs, and NPUs.

The SDK distinguishes itself by enabling the modernization of legacy applications, allowing developers to embed modern controls and platform features into existing projects without a full rewrite. It utilizes a native C++ projection for high-performance system interactions and employs NuGet-based distribution to decouple the framework version from the operating system, supporting side-by-side runtime execution.

Broad capability areas include comprehensive application lifecycle management, hardware-accelerated visual rendering, and flexible deployment options for both packaged and unpackaged applications. It also covers resource management for localized assets, process-isolated sandboxing for security, and integration for system-level notifications and widgets.

The framework supports structural patterns such as the Model-View-ViewModel architecture to decouple application data from the user interface.
