The Type or Namespace ‘Linq’ does not exist in the namespace ‘System’
October 29th, 2009 — Brian FooteToday I got this error simply adding a master page to a solution, which included a line for ‘using System.Linq’:
“Type or Namespace ‘Linq’ does not exist in the namespace ‘System’.”
The thing is, Linq exists in System.Core, not System. So why the bogus error? Seems like they wrongly put the Linq code into the System namespace. And just how would one know where to find Linq if one didn’t remember it’s in System.Core? You would be reduced to searching Google (which is probably how you got here after all!).
