Devart Forums

I work on an asp.net project that uses dotConnect for Oracle.
All sources and libraries are under Source Control.

The first version of my project in .net 4.0 used EntityFramework 4 and
dotConnect for Oracle 7.2.122.0
Currently I am in second version in .net 4.5 with EntityFramework 5 and
dotConnect for Oracle 7.7.267.0

Because the first version had an urgent bug, that has to be fixed immediately,
I had to switch back and fix the bug.
Everything is compiling fine, but when I start my project, I get the error
"Unable to determine the provider name for connection of type 'Devart.Data.Oracle.OracleConnection'"

All references are set correct. It worked fine before. For me, it seams, that
I con not switch back to an older version of dotConnect.

Hello!

I did not receive any answer until now. The fix is very important and urgent
for us. Thank you for any help.

1. Which version (x.xx.xxx) of dotConnect for Oracle is currently installed on your workstation?

2. Run your application in the debug mode and make sure (via Visual Studio > Debug > Windows > Modules) that the versions of Devart.* assemblies loaded in the process of your application correspond to the version of dotConnect for Oracle which is registered in the *.config file of your application.
If this doesn't help, please send us a test project so that we can reproduce the issue in our environment.
