I'm facing this strange problem.
Before this, I had installed Oracle 12c Client in my machine, but my Oracle Database was 11gR2 all the time.
After I have completely uninstalled Oracle 12c and Oracle 11gR2 (Followed the instruction from Oracle forum and etc) this strange behavior occur.
Currently my machine has installed:
- Oracle Database 11gR2
- Oracle ODAC 11.2.0.1 64 Bit
However when I build my application, it shows What I have tried:
- Remove the Oracle.DataAccess.dll from the project reference and add it back again
- Toggle 32-bit / 64-bit build option
I have tried with 2 projects,
- Web Application - Visual Studio 2005
- Windows Application - Visual Studio 2013
Both behave the same way. So I don't think this has anything to do with Visual Studio / IIS and this is really not a right time to format my machine.
Anyone had this problem before? Thanks.
Ps: Sorry for my bad english
