Having installed managed ODP.NET on my computer, the ODP.NET Managed Driver does not appear inside the Choose Data Source dialog in Visual Studio 2013 Professional.
This is how it should look like:
This is how it actually looks on my machine:
I've followed the steps described in the "An Easy Drive to .NET" article on the Oracle website.
I've also installed the Oracle Developer Tools for Visual Studio. Still no managed driver to select.
My question:
Is there anything I forgot to do in order to make the data provider appear?
Open your Registry editor and check if RegKey HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319\AssemblyFoldersEx\odp.net.managed
exists. It contains only the (Default) value with location of your Oracle.ManagedDataAccess.dll.
Add the key in case it is missing, example:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319\AssemblyFoldersEx\odp.net.managed]
@="c:\\oracle\\product\\12.1\\odp.net\\managed\\common"
You can also try the Oracle config scripts at {ORACLE HOME}\odp.net\managed\x64\configure.bat
and {ORACLE HOME}\odp.net\managed\x86\configure.bat
, they should do the same
Then check your compile options whether you selected target Framework at least to .NET Framework 4
.
Update for Release 12.2
Key odp.net.managed
seems to be used in old version 12.1. Latest release uses Oracle.ManagedDataAccess
:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319\AssemblyFoldersEx\Oracle.ManagedDataAccess]
@="C:\\oracle\\product\\12.2\\Client_x64\\odp.net\\managed\\common"
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319\AssemblyFoldersEx\Oracle.ManagedDataAccess.EntityFramework6]
@="C:\\oracle\\product\\12.2\\Client_x64\\odp.net\\managed\\common\\EF6"
