Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type
IDataAccessAdapter. When you use instance method syntax to call this method, omit the first parameter. For more information, see
Extension Methods (Visual Basic) or
Extension Methods (C# Programming Guide).
Remarks Equal to calling adapter.FetchEntityCollection(), so entities already present in collectionToFill are left as-is.
If the fetch has to take into account a Context, the passed collectionToFill has to be assigned to the context before calling this method.
