i have installed ODT 112030 and then opened visual studio ultimate then tried to add new connection to the oracle DB, but every time i try to test connection of click on OK , visual studio crashes ?
did that happen with anyone before ?
There was an issue with the ODAC version from last year where OCI.DLL was being locked and if someone installed into the same Oracle home, the DLL was old and out of synch with the rest of the DLLs. This could result in a crash.
Try reinstalling ODAC into a new Oracle home (new directory) and see if the problem goes away.
I'm assuming you are using VS2010 or earlier, not the VS11 beta.
