Consequence of not implementing this method in your data provider
As this method is virtual, you may think that you have an option of not implementing this method in your .Net Data Provider if functionality implemented in DbConnectionStringBuilder class is sufficient. However, the base method returns null instead of an object of DbConnectionStringBuilder. Hence, connection through Visual Studio to use your data provider with Entity Framework fails while adding ADO.NET Entity Data Model item to your application. To avoid this problem, override this method in your provider factory class and return object of DbConnectionStringBuilder if this class functionality is sufficient or object of your own class derived from DbConnectionStringBuilder.
