Devart Forums

Hi,

I'm getting the following exception when I try to UPDATE an existing model from the Database using des VS-EF-Designer Dialog. If I recreate the model everything works as expected, but this is hardly an acceptable workaround. Any ideas to make updating EF Models work?

-Regards kinl99

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.Data.Entity.Core.MetadataException: Schema specified is not valid. Errors:
(7,8) : error 0152: No Entity Framework provider found for the ADO.NET provider with invariant name 'Devart.Data.Oracle'. Make sure the provider is registered in the 'entityFramework' section of the application config file. See http://go.microsoft.com/fwlink/?LinkId=260882 for more information.

This means that registration of Devart.Data.Oracle in *.config file of your application is correct.

Looks like you have encountered a bug with the Update Model From Database functionality of EDM Wizard/Designer. Please contact the Microsoft support team.

As a workaround, please use Entity Developer (the Devart Entity Model item, *.edml) instead of EDM Wizard/Designer (the ADO.NET Entity Data Model item, *.edmx): http://www.devart.com/entitydeveloper/ed-vs-edm.html.

The bug with the Update Model From Database wizard in Entity Framework 6 Tools for Visual Studio 2012 and Visual Studio 2013 is fixed in the current build of dotConnect for Oracle.
