Implements

IVsDataProviderObjectFactory.CreateObject(Type)

Remarks

A provider implements this method to return top-level support entities, that is, those normally created directly by a client as opposed to indirectly by querying a data connection for a service or creating a type referenced from a data support XML file.

DDEX support entities that you can create by using this method:

• IVsDataConnectionPromptDialog

• IVsDataConnectionUIControl

• IVsDataConnectionProperties

• IVsDataConnectionSupport

• IVsDataProviderDynamicSupport

• IVsDataSourceSpecializer

• IVsDataViewSupport

• IVsDataConnectionEquivalencyComparer

• IVsDataConnectionUIConnector

• IVsDataConnectionUIProperties

• IVsDataConnectionUITester

Objects that implement the other support entity interfaces are created by other means, such as indirectly by querying a data connection for a service or creating a type referenced from a data support XML file.

Notes to Inheritors:

The derived class must override this method.
