Multiple versions of Oracle.DataAccess.dll on the same machine?
928769Apr 5 2012 — edited Apr 6 2012My group has developed several .NET apps that were optimized for the Oracle 11.2.0.1 client and older versions. I recently installed the latest Oracle 11.2.0.3 client on my development machine to take advantage of the Entity Framework support.
When testing out the new 11.2.0.3 client on our user's machines, I found out that some of the older apps don't work with the new client. I am hoping to allow apps that require either the latest 11.2.0.3 client or older versions to live in harmony on our user's machines. Is there a way to do this?
I have a test environment with Oracle 11.2.0.1 installed. I manually loaded Oracle.DataAccess.dll v11.2.0.3 and its policy file into the GAC (so that both the 11.2.0.1 and 11.2.0.3 .dlls are now present), but the app that depends on the latest version still doesn't work. Is there something else that I need to do?
