WebXaml is a framework allowing you to use Windows Presentation Foundation into ASP.NET.
WebXaml aim to create images in different formats using XAML so you can exploit the WPF power, easier than GDI+, for elaborated images such as 3D, charts and so on.

WebXaml library contains:

• A Dispatcher pool (default 10 threads), one for Window. Each thread satisfies one request in the ASP.NET context;
• A build provider compiling .wxaml files and code file (if needed), and transforming XAML code into BAML persisted into assembly resources;
• An HTTP Handler factory (XamlPageHandlerFactory) to give the appropriate IHttpHandler for any path;
• An async HTTP Handler that inherits by XamlPage to process the request.

To use it you have to create a .wxaml file containing a new directive followed by XAML code:

1
2
3

<%@ XamlPage ImageType="Png" Width="700" Height="600" %>

<!-- Xaml code -->

If you call the path using a browser you will receive an image as answer like this:
