Method DeferredAll

DeferredAll<TSource>(IQueryable<TSource>, Expression<Func<TSource, Boolean>>)

This method is the deferred implementation of the extension method . In EF some linq operations are performed on the client end instead of the server. Therefore, if we use the regular method it will cache the data from the database before performing the actual "All" operation. To cater to this, we provide with a deferred implementation that delays the caching so that only the result can be cached.
