Question

At work we have just started developing in C#.NET using VS2008 and we need to connect to Oracle databases.

The problem is that we are still using Oracle 10g servers and Oracle provide four install options:

• Install the Oracle 10g DAC with tools for VS2005 / VS2003
• Install the Oracle 11g DAC with tools for VS2008
• Install Oracle 10g DAC
• Install Oracle 11g DAC

We would prefer to use the 10g DAC but with VS2008 tools…

I’m wondering if anyone knows of any issues we might face using the 11g DAC on a 10g database – are the DACs backwards compatible?

So far it seems ok and we can connect and make queries with it but I have little experience working with Oracle databases, thanks for any pointers!

Answer 1

I’ve been using Visual Studio 2008 with Oracle 11g DAC (with tools) running against Oracle 10gR2 for many months now without any real issues.
