We need an option to set the ProviderManifestToken in code for a Database First Model in order to override the value from the EDMX, which defaults to "2012" for SQL Server 2012 in our particular case.
What we've tried so far: As described in this post we decorated our context class with the DbConfigurationType attribute, our derived class looks exactly the same as in that post.
internal sealed class MyDbConfiguration : DbConfiguration { public MyDbConfiguration() { //this.AddDependencyResolver(new SingletonDependencyResolver<IManifestTokenResolver>(new ManifestTokenService())); this.SetManifestTokenResolver(new ManifestTokenService()); } } As you can see, we tried 2 different things here, AddDependencyResolver and SetManifestTokenResolver.
When we start the application program execution enters the constructor of MyDbConfiguration - and that's it, the dependency resolver itself
internal sealed class ManifestTokenService : IManifestTokenResolver { private const string SqlServerManifestToken = @"2005"; private static readonly IManifestTokenResolver DefaultManifestTokenResolver = new DefaultManifestTokenResolver(); /// <inheritdoc /> public string ResolveManifestToken(DbConnection connection) { if (connection is SqlConnection) { return SqlServerManifestToken; } return DefaultManifestTokenResolver.ResolveManifestToken(connection); } } is never invoked so it seems we've reached a dead end here. Has anyone had the same problem and found a solution?
