Remarks
Implements the IVsDataReader and the IVsDataReaderDescriptor interfaces. This class takes as input a DbDataReader object and exposes the schema of the DbDataReader object as a DDEX DataReader.
The format of the data reader exposed is that required by the DeriveSchema(String, DataCommandType, [], Int32) method, which has a fixed set of columns. It does not expose exactly the same information that is provided when calling the GetSchemaTable method on the underlying DbDataReader instance.
