Application is having a Model and Its DBContext. While creating controller under template "Controller with read/write actions and views, using Entity Framework" giving me an error "Unable to retrieve metadata for '<ModelClass>'. A null was returned after calling the 'get_ProviderFactory' method on a store provider instance of type 'System.Data.OracleClient.OracleConnection'. Thre store provider might not be functioning correctly". Connection string is correct. please help me..

Hi Strambake,

Welcome to the MSDN forum.

Which version of Entity Framework do you use?

Your problem is related to a third party data provider, so please try to use this version:

in addition, please take a look at this page: http://forums.asp.net/t/1781662.aspx/1

There are many connection string samples you can refer to: http://www.connectionstrings.com/oracle

Good day.
