is ambiguous in the namespace ASP

Question

I have a Visual Studio Website project, which gives me an error on compiling all of a sudden - it used to work just fine.

It tells me that my "Validator_ascx" control is ambiguous in the namespace ASP.

I've read a lot of topics about this particular problem, but none solved my issue so far. Things I've tried include:

Check for doubles. There are NONE. Nothing else is called Validator in my entire project.
Rebuild/Clean Website
Rename control and update reference in Web.config
Changed the TEMP build folder to a new folder via web.config, to make sure that nothing remains from previous builds.
Tried putting my code-behind of Validator (Validator.ascx.cs) into a new namespace.
Tried turning 'batch' compilation to 'false' in web.config

All of them lead to the exact same error. I'm getting desperate. Does anyone else have any ideas of things I can try? I've lost almost an entire day due to this error.

Thanks for any ideas you might have.

If you just remove the validator, the code compiles without an problem? — tlbignerd, Jul 16 '13 at 15:44
Any chance compiled DLL of the project is in the Bin folder? — Yuriy Galanter, Jul 16 '13 at 15:46
If I take away the validator, it doesn't compile at all, because the validator is used all over the website. — Steven Lemmens, Jul 16 '13 at 15:47
Have you tried this solution http://stackoverflow.com/a/904018/989348 — Full Time Skeleton, Jul 16 '13 at 15:49
Yes, I've tried putting batch compilation to 'false' in the web.config. That's essentially what he's doing. Same problem. — Steven Lemmens, Jul 16 '13 at 15:54
Did you notice `Abdul Saboor` suggestion in the same SO question taken from http://www.netomatix.com/development/usercontrols2.aspx might help specifying a classname? It's almost like it is trying to compile the control multiple times. — user692942, Jul 16 '13 at 17:28
Yes, If I try to put the ClassName there, then the error message will simply change to 'ClassName is ambiguous in the namespace ASP', where 'ClassName' is what I've entered ... — Steven Lemmens, Jul 17 '13 at 08:26
