> Right now the CsvDataContext supports reading just a single file and having that as a single table. It would be wonderful if you could also instantiate CsvDataContext (or some other class) with a folder instead of a file, and then have every csv file in the folder show up as a table in the schema. That would allow CsvDataContext (or whatever it will be) to be used as a functional replacement for almost any other UpdateableDataContext, e.g. for testing etc.
