I was asked by Jiri Cincura to write my question here on the list, so here am I
now:
(From here on its a copy from my initial issue on the tracker from firebird -
notice that the link to the tracker doesnt work because the related issue got
deleteb by Jiri)
Key: DNET-525
URL: http://tracker.firebirdsql.org/browse/DNET-525
Project: .NET Data provider
Issue Type: Bug
Components: ADO.NET Provider
Affects Versions: 3.2.0.0
Environment: Win7 - EF 6 - .Net Provider 3.2.0.0 - Firbird 2.5 -
Visual Studio 2013
Reporter: Rand Random
Assignee: Jiri Cincura
I am getting following error message:
The 'Instance' member of the Entity Framework provider type
'FirebirdSql.Data.FirebirdClient.FirebirdClientFactory,
FirebirdSql.Data.FirebirdClient, Version=3.2.0.0, Culture=neutral,
PublicKeyToken=3750abcc3150b00c' did not return an object that inherits from
'System.Data.Entity.Core.Common.DbProviderServices'. Entity Framework providers
must inherit from this class and the 'Instance' member must return the
singleton instance of the provider. This may be because the provider does not
support Entity Framework 6 or later; see
http://go.microsoft.com/fwlink/?LinkId=260882 for more information.
I probably did something wrong but dont know what...
I am currently trying to update my VS 2012 + EF 5 Solution to the latest VS
2013 and EF 6.0.0.1 Versions, everything went smoothly and I am able to build
the solution.
During the update I noticed that the .Net Provider is also availabe in a NuGet
package, and got my latest version for EF 6 from there. (Yeah I noticed that
there are 2 different NuGet packages and picked the one saying "Firebird
ADO.NET Data provider (Entity Framework 6).
When I tried to run the application a very simple linq query resulted to an
exception telling me that the provider isnt configured in the app.config.
So I extended the default config from
<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>
to
<entityFramework>
<defaultConnectionFactory
type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework"
/>
<providers>
<provider invariantName="System.Data.SqlClient"
type="System.Data.Entity.SqlServer.SqlProviderServices,
EntityFramework.SqlServer" />
<provider invariantName="FirebirdSql.Data.FirebirdClient"
type="FirebirdSql.Data.FirebirdClient.FirebirdClientFactory,
FirebirdSql.Data.FirebirdClient" />
</providers>
</entityFramework>
After this the excpetion was gone and a new one appeard - the one mentioned at
the very top.
So what am I doing wrong and how can I tell my solution to use the DLL for EF 6?
