An issue I faced today while testing the Playstation Suite SDK, I created a sample project in the PSS Studio and added a reference to a custom made DLL.

I found that the intellisense (auto completion) of the editor couldn't perceive the newly added DLL, it provided no auto-completion for the classes within the library.

I got the solution to this from here http://www.gamefromscratch.com/post/2012/04/20/Initial-issues-with-Playstation-Suite-SDK.aspx

just restart the PSS Studio and everything will work just fine
