Can someone tell me where such a reference is coming from?

SqlXmlCommand loCmd = new SqlXmlCommand(ConnectionManager.GetConnection().ConnectionString);

Is this something that is built in C#?

I see also that, in the sample code that I have, there are some properties that are getting some values such as:

loCmd.SchemaPath = Server.MapPath(lcXSD);

lcXSD here is a parameter passed to the method. So, it exists. This represents the XSD schema file that the returned XML should conform to. I seem to understand that, in C#, the SQLXMLCommand() will generate the proper XML as per the XSD schema file passed. However, I have to translate all that in VFP. No such thing exists, correct? Would that mean I would have to parse line by line the XSD file and generate the XML to be returned accordingly to the schema?
