Unable to find the requested .Net Framework Data Provider. It may not be installed.
Oct 29, 2011 05:57 PM|LINK
I have Oracle 10g installed on my machine.
Error :
Unable to find the requested .Net Framework Data Provider. It may not be installed.
Line of code :
DbProviderFactory objFactory = DbProviderFactories.GetFactory("Oracle.DataAccess.Client");
(Working fine if i am using other options rather than DbProviderFactory)
Assembly :
Oracle.DataAccess (In GAC, i have version 10.1.0.200 only).
Please help me sort this error. Thanks
