When running something like the following:
IEnumerable txs =
where (tx.C300_STATE_COUNTRY.Contains("MD")
|| tx.C300_STATE_COUNTRY.Contains("VA")
|| tx.C300_STATE_COUNTRY.Contains("DC"))
select tx;

I get the following:
E:\Documents and Settings\Rob\My Documents\Visual Studio 2008\Projects\yet-another-test\yat\bin\Debug>yat
System.Data.CommandExecutionException: An error occurred while executing the command definition, see the inner exception for details. ---> C

The Contains method is causing the problem. Should I not be able to use this?

I think the driver is attempting to use an INDEXOF operator to search for the string which I don't think is present in oracle. Please advise.

Thank you for the bug report.
The situation is quite complicated.
We are working on the problem, please be aware that this will
take some time and plan your development strategy accordingly.
