Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IQueryable<T>. When you use instance method syntax to call this method, omit the first parameter. For more information, see https://msdn.microsoft.com/en-us/library/bb384936(v=vs.103).aspx or https://msdn.microsoft.com/en-us/library/bb383977(v=vs.103).aspx.

This method works by calling the AsNoTracking method of the underlying query object. If the underlying query object does not have a AsNoTracking method, then calling this method will do nothing.
