Devart Forums

When trying to generate an edm from my database (step four in http://www.devart.com/dotconnect/oracle ... html#model). I am getting an 'ORA 12154: TNS: Could not resolve the connect identifier specified.'

I get this error as soon as I click 'Ok'.

If I choose 'Direct' mode, then I can supply the SID and the connection test succeeds, but when I click 'Ok', I get an error that says 'The given key was not present in the dictionary.' and the connection is not saved.

Need Help. I am evaluating EF enabled 3rd party provider options.

Here is my genearal configuration:
VS 2010 Professional
Windows 7 64 bit
Oracle 10.2.0.1.0
(more info upon request)

I have the correct Oracle client installed. The TNS names file should also be fine (other applications such as SQL Developer are using it). I need assitance asap so I can proceed with a product recommendation/choice.

Do you have any third-party ADO.NET Data Providers installed?

Hello and thanks for the response. I had installed Progress Data Direct Oracle provider, but I removed it before I installed the Devart provider in my 'Add and Remove Programs' in the control panel. I tried restarting my machine, but I still get the same errors. Is there a file, set of files, or registry/variable setting that needs to be manually removed or altered?

Try to clear the cached Server Explorer view (it seems to be corrupt).
Go to %Application Data%\Roaming\Microsoft\VisualStudio\10.0\ServerExplorer\ and delete the DefaultView.SEView file.
