No, an .addin XML registration file is still created for you automatically by the Add-in Wizard. You do not need to create it by hand unless you are constructing your add-in manually, and not by using the wizard. By default, the .addin file is created in the same folder as your add-in project. For example, if you create an add-in project called MyNewAddinProj using the Add-in Wizard, it is put by default in the directory:
C:\Documents and Settings\BruceT\My Documents\Visual Studio 2005\Projects\MyNewAddinProj\MyNewAddinProj
The file name is the same as your project only with a .AddIn extension (ie. MyNewAddinProj.AddIn). If you are not finding one there, then something must be wrong. What version of VS 2005 are you running?
Incidentally, the latest builds of Help have updated topics on how to create and access satellite DLL files. You can find the top-level topic at:
ms-help://MS.VSCC.v80/MS.MSDN.v80/MS.VisualStudio.v80.en/dv_extcore/html/a1e5a4ce-e596-4dda-b316-8f5588b478fe.htm
HTH!
