I have dotConnect "9.4.348" licanse version. And I can`t generate .edmx model from Oracle Database Express Edition 11g Release 2.
I use this tutorial (https://www.devart.com/dotconnect/oracl ... al_ef.html), but I have next error:
Unable to generate the model because of the following exception: 'System.Data.Entity.Core.EntityCommandExecutionException: An error occurred while executing the command definition. See the inner exception for details. ---> System.InvalidOperationException: Unknown active document.
