If the type of source implements System.Linq.IQueryable`1, Queryable.AsQueryable(IEnumerable) returns it directly. Otherwise, it returns an System.Linq.IQueryable`1 that executes queries by calling the equivalent query operator methods in System.Linq.Enumerable instead of those in System.Linq.Queryable.

This method assumes that source implements IEnumerable`1 for some T. At runtime, the result is of type System.Linq.IQueryable`1 for the same T. This method is useful in dynamic scenarios when you do not statically know the type of T.
