	GetAssembly	Locates an assembly, given an assembly string and a data source GUID.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType()	Gets the Type of the current instance. (Inherited from Object.)
	GetType(Guid, String)	Retrieves a type definition, given a type name and a data source GUID.

Remarks

Some DDEX providers behave differently when connected to different data sources. The most extreme example is with generic providers like OLE DB and ODBC, whose specific providers or drivers define their behavior. A simpler example is the differentiation between a SQL Server connection and a SQL Server Database File connection.

Although the same provider is used to connect to each data source, the design time experience may be different. A DDEX provider can implement this class to provide ways of customizing the behavior of the provider, depending on its data source.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
