What problem does it solve?

WebView2 bridge messaging in WPF often suffers from cross-thread access issues when asynchronous handlers resume on a thread pool, risking UI thread violations.

Core Features & Use Cases

• Dispatcher-aware initialization: initialize services after InitializeComponent to capture a valid Dispatcher
• Thread-safe message posting: marshal WebView2 messages to the UI thread via the Dispatcher
• Robust async handling: use ConfigureAwait appropriately and central Post method to ensure safe messaging
• Use Case: building a WPF app with a WebView2 bridge that posts results from background tasks to the UI

Quick Start

Implement the initialization pattern in your WPF app to ensure dispatcher-safe messaging for WebView2.
