Remarks
Queries returning a scalar value are called "immediate execution" queries within LINQ. These queries don't actually exist as a query object, but execute immediately to return the desired value. For example, _entityManager.Employees.First() does not return a query, it instead executes immediately, and synchronously, to return the first employee object. When only asynchronous queries are supported, for example in Silverlight applications, converting the query to the IEntityScalarQuery allows you to then use the scalar methods in an asynchronous query.
For more information on extension methods, see Extension Methods (C# Programming Guide) or Extension Methods (Visual Basic) in the Visual Studio 2008 documentation.
