asp.net - Unrecognized tag prefix or device filter 'asp' in VS2012

Question

I recently installed VS2012 and working on work projects that I used to work on with VS2010. I never had an issue with VS2010 not recognizing asp prefixed tags but VS2012 is. I tried deleting the ReflectedSchemas folder under

C:Users[User_name]AppDataRoamingMicrosoftVisualStudio11.0

but still not working. Anyone ran into this issue in VS2012?

Answer 1

Closing and reopening the file (.aspx file not solution) from solution explorer worked for me in visual studio 2015. Before trying anything else you can give it a try.
