Hi, I have asp.net project in VS 2008.

In my asp.net project, I want to add reference to an assembly(oracle.dataaccess.dll) which is inside GAC. But when i do 'add reference', i do not see that dll in add reference list. I think i should that dll in add reference list without doing browse.

Can any one clarify why it is not appearing in add reference list?

Your help highly appreciated !!!

There are 5 tabs on the add reference window. If you are sure that you have put it in the GAC, you should be able to see it on the .Net tab.

As i install ODP.Net, the oracle.dataaccess.dll is by default in GAC. I can see that in GAC so i think i should see that in Add Reference panel without using browse option.

Yes you dont have to use browse option. Just look at the .Net tab.

thanks for reply. Ok let me explain this way...
I have two version on oracle.dataaccess.dll, one is for 9i and another is 10g. Both are in GAC.
Now when i do add reference in VS 2008, i can see only 9i dll so i do not have to do browse for that. And dll for 10g does not appear in that list so i have to do browse. Any idea why it is making difference between them even both are in GAC. I know i can do browse but my question is what would be the reason for not showing that dll.

Sounds weird. Did you, just in case, tried to uninstall v.9i and install v.10g only?

sounds weird to me also... that was the reason for posting this question

Have you, by any chance, tried to GAC the DLL manually?

No. I think i don't have to GAC, because odp.net installation does GAC for me.

Just ran into the same problem.
So as a future reference, this is how you fix it:
You add a pointer to the DLL in the Registry like this:

[HKEY_CURRENT_USER\SOFTWARE\Microsoft\.NETFramework\AssemblyFolders\MyAssemblies]@="C:\\MyAssemblies"

Normally this should have been done automatically by Oracles installer, but if you install things in the wrong order this doesn't happen.
