I got a new ADO.Net Entity Model (an .edmx file) and I want to map it to the database.

I left-click the model --> Generate Database from Model..--> Set the connection string using devart's connector and tested OK.

Then I get this error:

Running transformation: System.InvalidOperationException: The SSDL generated by the activity called 'CsdlToSsdlAndMslActivity' is not valid and has the following errors:
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.

My app.config:

I'm extracting the model from a MVC Application and mapping it to a new Oracle Database.

Any clue?

Thanks in advance.

Please replace

Code: Select all

Devart.Data.Oracle, Version=8.1.45.6

with

Code: Select all

Devart.Data.Oracle, Version=8.1.45.0

in your app.config.

Already tried that... And no effect..

Now I'm trying to cerate a new model, importing an already existent DB.

The app.config:

Code: Select all

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->

  </configSections>
  <DbProviderFactories>
    <remove invariant="Devart.Data.Oracle" />
    <add name="dotConnect for Oracle" invariant="Devart.Data.Oracle" description="Devart dotConnect for Oracle" type="Devart.Data.Oracle.OracleProviderFactory, Devart.Data.Oracle, Version=8.1.45.0, Culture=neutral, PublicKeyToken=09af7300eec23701" />

    <!--<defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
      <parameters>

      </parameters>

    <providers>

    </providers>
  </entityFramework>
</configuration>

And get this error:

Your current version of dotConnect for Oracle is 8.1.45, isn't it? If yes, try this app.config:

Code: Select all
