Hello,
I am using dotConnect for Oracle 6.70.293 with VS2010.
Everything was fine. One day I installed VS2012.
Now VS2010 is not working. When I try to update model (edmx file) from DB, I get this error:
"The data reader returned by the store data provider does not have enough columns for the query requested".
Even uninstallation of VS2012 doesn't fix the problem.
Can you help me?
Thanks.
Updating model from DB fails
Re: Updating model from DB fails
VS2012 installs .NET 4.5 which is in-place upgrade of .NET 4.0 (no roll back is possible). .NET 4.5 is supported by dotConnect for Oracle starting from the 7.2.77 version: http://www.devart.com/dotconnect/oracle ... story.html. Please upgrade your dotConnect for Oracle and notify us about the result.

Thank you very much. I have upgraded dotConnector to the version 7.6.202 (trial version) and now Entity Framework is working correctly.
