Strange Behaviour in VS 2005 With Master Pages & User Controls

[Mike L]

Whenever I create a master page (or a user control), the VS environment doesn't create the code-behind links, nor, if I do it manually, which, of course, I shouldn't have to, it doesn't link them, call the .cs, understand the code file is there, or even show it in the window when Intellisense tries to locate it with the codefile directive. Strange. It shows both files when added to the Project Browser view (the "template".master, and the "template".master.cs), but it doesn't put one indented under the other, indicating linkage, like it does with normal web pages (.aspx). I have exactly the same problem with user controls (.ascx) I can't figure out why, and have apparently applied all latest fixes. Can anyone help me diagnose this? I suppose I could back everything up (projects), delete and reinstall, but it seems like it ought to be simpler than that.... Thanks!!
