Devart Forums

Hi,

I am currently using Devart 6.50 version for creating WCF Data services when i upgraded to Devart 7.0 i am unable to run my services. Getting below exception

"The server encountered an error processing the request. Please see the service help page for constructing valid requests to the service. The exception message is 'Exception has been thrown by the target of an invocation.'. See server logs for more details. The exception stack trace is:

Does anybody faced the same issue.
Please do let me know important things to take care before upgrading it to higher version.

There are no Devart.* classes in the stack trace. It seems like dotConnect for Oracle is not the reason of the problem. Otherwise, please localize the issue and send us a small test project to reproduce the problem in our environment.
