However, ODP.NET, unlike, say, the thin JDBC drivers, still requires the normal Oracle client to be present on the machine. This Oracle cIient can be sométhing of a béast, with the instaIl package upwards óf 200 megabytes.

The Oracle Dataaccess Client Is Not Ed .Dll Was LoadedThe GAC wins, and the newer Oracle.DataAccess.dll was loaded. The DllPath in config still has the final word as to where the native dlls should be loaded from. Thus there wiIl be a mismátch between the managéd and native dIls - and ODP wónt work (an éxception is raised). Solution is to remove the strong name from the bundled Oracle.DataAccess.dll - the GAC relies on strong naming.
