When a Connection object throws an exception and tells you 'all pooled connections were in use and max pool size was reached', it usually has to do with bad code.

The DbTransactionWrapper

I now rewrote the class so it fits in the more generic approach given by ADO.NET 2.0. So behold: The DbTransactionWrapper!
