Hello All,
Something broke in my VS2010 installation and I can't figure it out.
[the problem first became apparant in my existing site, so I tested the problem with a clean, new website]
If I create a brand new website, I get a warning underline (green sqiggly line) under the "<asp:Content ...>" tag. When I hover over the tag, I see the message "Validation (): Element 'content' not supported".
I've seen posts about resetting my settings (doesn't help) and about deleted the Reflected Schemas folder (I don't have one, for some reason). Also, if I try to create a new standard element (like a button), my intellisense does not come up (e.g.: I type "<asp:" and I don't see the usual list of controls come up).
The weird thing, is that if I reset the target framework to 3.5, everything is normal. But as soon as I set the framework back to 4.0 I start to see the erroneous behavior.
This is something that started happening just today, so I'm stumped as to what has happened overnight. Any suggerstions are appreciated.
