I can't find docs about APP in Visual Studio 2005 Beta2 Documentation.
Formerly (VS.net 2003 Combined Collection) - Library->Web Development->Networking->Asynchronous Pluggable Protocols

Try looking under:

Web Development->Internet Explorer Development->Asynchronous Pluggable Protocols

Ack...you're right. I just installed VS 2005 Beta 2 from scratch on a clean machine and cannot find the Async Plug Protocols content. I must have been looking on a server with the MSDN April 2005 Library installed because that's where I found the topics for Asynchronous Pluggable Protocols.

Are you able to download and install the MSDN April 2005 Library?
