Phoenix.dll is generated by a WebDeployment project that merges all .aspx and .ascx markup and code-behinds into a single assembly. It is located in the /bin folder of the web application. This assembly is not part of the Phoenix class library and therefore is not documented.

The assembly contains parsed page markup and .NET code only. Image files and other content in the web folder are not compiled into the assembly and will remain in their respective folders. The next section will take you through the web folders, pages and user controls and what they are used for.
