Hello!

Since you don't answere my questions in the other thread I tried some stuff on my own.
But I got stuck again.
I created a model with the built-in designer from visual studio
When I click "create database from model" I get this error:
"No Entity Framework provider found for the ADO.NET provider with invariant name 'Devart.Data.PostGreSql'. Make sure the provider is registered in the 'entityFramework' section of the application config file.

here my app config file:

Code: Select all

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />

Please change the version of provider from 7.3.352.6 to 7.3.352.0 (PostgreSQL), from 5.2.352.6 to 5.2.352.0 (SQLite) in the DbProviderFactories section, i.e.:

Code: Select all

<DbProviderFactories>
      <remove invariant="Devart.Data.PostgreSql" />
      <add name="dotConnect for PostgreSQL" invariant="Devart.Data.PostgreSql" description="Devart dotConnect for PostgreSQL" type="Devart.Data.PostgreSql.PgSqlProviderFactory, Devart.Data.PostgreSql, Version=7.3.352.0, Culture=neutral, PublicKeyToken=09af7300eec23701" />
      <remove invariant="Devart.Data.SQLite" />
      <add name="dotConnect for SQLite" invariant="Devart.Data.SQLite" description="Devart dotConnect for SQLite" type="Devart.Data.SQLite.SQLiteProviderFactory, Devart.Data.SQLite, Version=5.2.352.0, Culture=neutral, PublicKeyToken=09af7300eec23701" />
    </DbProviderFactories>
  </system.data>

The revision number of Devart ADO.NET providers in the entityFramework section is *.6 but it should be *.0 in DbProviderFactories. For more information, refer to http://blog.devart.com/entity-framework ... force.html.

Does this information help?

Have you rebuilt your solution after updating the config file and before adding new model?
If yes and it is not the reason of the issue, please send us your test project, so that we could investigate the issue more clearly.
