We have a .Net (v2) application that talks to a Oracle 10g server. The clients want to upgrade the web server to Windows Server 2008 R2 and upgrade the website to .Net 4.5. Apparently pre-11g clients do not work on this OS so I was wondering if anyone has tried to connect to a Oracle 10g database from .Net 4.5 using Oracle 11g client? Do you know if there's any issues with this? Any guidance would be much appreciated
11.2 client can talk to 10.2 database, and there should be no issues there.

Hope it helps,
