"Activation error occured while trying to get instance of type Database, key "DbDalFactory_ISuborderSplitInclusionProvider"?"
Already tried adding this key to the config file, also checked oracle.DataAccess versions referred in solution.
The error got resolved by installing the 32bit client for oracle, I was using 64 bit client earlier with a 32 bit provider, the client and provider should be same while creating database connections.
