  @ duttavr

  i'm wondering why you ask?  let me explain.

  if i want to use speech recognition in .NET 4.5, i would likely reference System.Speech.

  OTOH, if i want to use the sizeof operator keyword, it is not necessary to add any reference/assembly/namespace because sizeof is part of the c# language.

  The same applies to the operator keyword await ... from http://msdn.microsoft.com/en-us/library/hh156528(v=vs.110).aspx, you will note that  async modifier is a contextual keyword:

  The asynchronous method in which await is used must be modified by the async keyword.

  Such a method, defined by using the async modifier, and usually containing
  one or more await expressions, is referred to as an async method.

  sizeof, await, async, and other C# Keywords do not require any reference/assembly/namespace beause they are part of the c# language.

  I'm so sorry for the very late reply. Actually I solved it myself, but could not come back to this thread. Sorry for that.

  That was my first async CTP program, actually it was my mystake I used await without async.

  Many thanks for your reply.
