how frequently does the letter "n" appear in:
q: spservicecontext class not available in sharepoint i have made a web part in visual studio in which i am using the following class:
microsoft.sharepoint.spservicecontext

it is working fine. then i created a new visual web part project and tried to use this but it says:

the type or namespace name 'spservicecontext' could not be found (are
  you missing a using directive or an assembly reference?)

even though i have already added microsoft.sharepoint at the top plus i have added its reference in project.
how to fix this?

The passage contains twenty-eight "n"s.
