No Data Source in entity data model wizard RRS feed

  • Question

  • I am working with VS2010 SP1, I have installed ODAC1120320_32bit for asp.net4 and my database is Oracle 11.2.0.  I can create a connection to my Oracle database via data connections in the server explorer tab but I had to put in TNS_ADMIN in my environmental variables in Windows 7.

    When I try to add an ADO.NET Entity Data Model and select generate from database, there are no database connections to select from (the dropdown is blank) and I cannot enter anything into the "Entity connection string".  Do I need to install all the ODAC products?

    Thanks, in advance.
