Upgrading GP Addin Mods to use EF6

After adding the configuration sections to Dynamics.exe.config

<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
<entityFramework>
<defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
<providers>
<provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
</providers>
</entityFramework>

and adding the connnection strings section, the following error  occurs…

Top-level Exception
Type: System.InvalidOperationException
Message: The Entity Framework provider type 'System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer' registered in the application config file for the ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded. Make sure that the assembly-qualified name is used and that the assembly is available to the running application. See http://go.microsoft.com/fwlink/?LinkId=260882 for more information.

Seems that as I have all the data access defined in its own class lib, there is no code causing a reference to force the correct EntityFramework.SqlServer.dll to be pushed to the build output.

So this hack did the job for now and I’ve posted this here to come back to another time.

Stack overflow post: EntityFramework.SqlServer.dll not is getting added

private void FixEfProviderServicesProblem()
{
// The Entity Framework provider type 'System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer'
// for the 'System.Data.SqlClient' ADO.NET provider could not be loaded.
// Make sure the provider assembly is available to the running application.

var instance = System.Data.Entity.SqlServer.SqlProviderServices.Instance;
}
