How do I host local HTML and JavaScript content in a MAUI application?▼

Local HTML and JavaScript content is hosted in MAUI by configuring a web root at Resources/Raw/wwwroot and setting a DefaultFile entry point for the HybridWebView to render.

Can I expose C# methods to JavaScript using MAUI HybridWebView?▼

Yes, you can expose C# methods to JavaScript by registering an invoke bridge via SetInvokeJavaScriptTarget, which establishes a JSON-serialized interop surface for JavaScript-to-.NET callbacks.

What is the best way to set up bidirectional communication between local web assets and .NET MAUI?▼

The best way to set up bidirectional communication between local web assets and .NET MAUI is using HybridWebView with a registered invoke bridge and a configured web root to handle JSON-serialized messaging.

Does MAUI HybridWebView require a specific folder structure for local web content?▼

Yes, MAUI HybridWebView requires a specific folder structure where local web assets must be placed under the Resources/Raw/wwwroot directory to properly load and render the configured DefaultFile.
