This folder documents best practices that WebView2 developers should follow when building applications that host the WebView2 control. The goal is to capture practical, API‑level guidance — informed by real issues that developers have run into — so that new and existing WebView2 apps can avoid common pitfalls around lifecycle management, navigation, security, performance, and platform integration.

Each document focuses on a specific app model, platform, or scenario, and is organized around two questions for every recommendation:

• Best practice — what you should do.
• Why? — the reasoning, and what can go wrong if you don't.

• UWP best practices — guidance for hosting WebView2 inside Universal Windows Platform (UWP) applications.

If you have hit a problem in your own app that you think other WebView2 developers would benefit from knowing about, feel free to open an issue or a pull request proposing a new best practice. Please keep entries:

• API‑level and product‑agnostic — describe the WebView2 API behavior and the recommended pattern, not implementation details of any specific app or internal product.
• Actionable — readers should be able to apply the guidance directly in their own code.
• Justified — always include the Why? so readers understand the trade‑off and can decide how it applies to their scenario.
