Remarks
This class contains a set of constant strings that indicate the names of well known data source information properties. A data provider is welcome to add more properties to their implementation but these will not be used generically.
The base class implementation, by default, reads properties and property values from the registry that are specified in a DataSourceInformation key, under SupportedObjects, if any. This provides an easy way to specify static data source information property values.
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.
