Are you sure the latest build of your DLLs are copied to the umbraco site?

Try a complete rebuild, usually does the trick.

I doubt this has anything to do with it being Umbraco Juno.

Hi Thomas,

  thanks for your reply, however I am using the latest build and have copied it to the bin folder of umbraco site. I've also notice one other strange thing.

  Unless I copy the ascx.cs file to the usercontrols, where I copied user control .ascx files in the first place, the control won't render.

  This is the error displayed (from umbrco stacktrace):

Error creating usercontrol (usercontrols/TPActive.ascx)
The file '/usercontrols/TPActive.ascx.cs' does not exist.

  If I copy the codebehind files then the usercontrol renders, and now even I do get an unempty breakpoint circle when I attach my vs2010 to w3wp, however I've not yet ever gotten a break triggered (even though I think I've placed breakpoints in vs2010 on more than engough places to get triggered at least once - i've even tried placing breakpoints inside usercontrol's ascx.cx Page_Load() event handler).

  So what's the deal plase? I've not used .NET4 with umbraco yet, but I'm guessing it should be preety much the same as with 3.5, make an .ascx, compile it, copy just the .ascx to umbraco's usercontrols folder, add a macro to umbraco using new .ascx control, copy the dll built from the .ascx to the bin (am I missing something please)?!?!

  TIA all again

Are you using a Web Application project or a Web Site project in Visual studio?
