[EF6] Error after updating to 6.8.322.0

[joozek]

Hi,
I recently updated to 6.8.322.0, just downloaded and installed binaries on my computer. Now when I first try to use EF it throws exception:

Code: Select all

The 'Instance' member of the Entity Framework provider type 'Devart.Data.PostgreSql.Entity.PgSqlEntityProviderServices, Devart.Data.PostgreSql.Entity, Version=6.8.322.0, Culture=neutral, PublicKeyToken=09af7300eec23701' did not return an object that inherits from 'System.Data.Entity.Core.Common.DbProviderServices'. Entity Framework providers must extend from this class and the 'Instance' member must return the Singleton instance of the provider.

• Version 6.8.322.0 is not mentioned anywhere in my project, I reference old dlls (6.7), located in my project directory. Changing them to 6.8 doesn't help
• I have following entries in my app.config:

  Code: Select all

   <entityFramework>
        <defaultConnectionFactory type="Hakon.Estomed.DataAccess.Base.PgSqlConnectionFactory, Estomed.DataAccess" />
        <providers>
          <provider invariantName="Devart.Data.PostgreSql" type="Devart.Data.PostgreSql.Entity.PgSqlEntityProviderServices, Devart.Data.PostgreSql.Entity, Version=6.7.287.6, Culture=neutral, PublicKeyToken=09af7300eec23701" >
          </provider>
        </providers>
      </entityFramework>
    
      <system.data>
        <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=6.8.322.0, Culture=neutral, PublicKeyToken=09af7300eec23701" />
        </DbProviderFactories>
      </system.data>
  

  I tried changing the version in app.config (and removing them altoghter), again no success
• I have also tried all mentioned solutions with version 6.8.333.0, to no avail

If you are currently using dotConnect for PostgreSQL v 6.8.322, please update your app.config correspondingly: change 6.7.287.6 to 6.8.322.6.

Sorry for long delay.

please update your app.config correspondingly: change 6.7.287.6 to 6.8.322.6.

It didn't help unfortunately.

1. You are currently using dotConnect for PostgreSQL v 6.8.322, aren't you?
2. Have you updated EntityFramework.dll used in your project? The \Program Files (x86)\Devart\dotConnect\PostgreSQL\Entity\EF6\Devart.Data.PostgreSql.Entity.dll assembly is compiled with Entity Framework 6 Release Candidate 1 starting from the 6.8.322 build: http://www.devart.com/dotconnect/postgr ... story.html.

1. I tried both 6.8.322 and 6.8.333
2. Yes, I updated EF to 6-rc1

Please send us a small test project which reproduces the error.

Nevermind, my co-worker managed to upgrade without any problems. I don't know what I was doing wrong, maybe I overlooked something.
Thanks anyway.
