Resolve custom dependencies

[lexon0011]

I use Unity in my project to register and resolve dependency. To tell AutoFac how to resolve a custom dependency a write the following working code for my IdentityServerServiceFactory

IdentityManagerServiceFactory factory;
factory.Register(new Registration<RoleManager<PlatosRole, Guid>>(res => (RoleManager<PlatosRole, Guid>)ServiceLocator.Current.GetInstance<IPlatosRoleManager>()));

I couldn't resolve my custom dependency for the IdentityAdminServiceFactory, because the Register method has only a parameter for an optional string.

IdentityAdminServiceFactory factory;
factory.IdentityAdminService = new Registration<IIdentityAdminService, IdentityAdminManagerService>();

I need a way to tell autofac, how it should resolve my dependencies, because in the IdentityAdminManagerServiceI need my IDatabaseConfiguration, which could not resolved at the moment:

public IdentityAdminManagerService(IDatabaseConfiguration databaseConfiguration)
      : base("IdentityDbContext")
{
   // databaseConfiguration could not resolve here!!
}

What is the correct way to resolve my dependency in the Register method of IdentityAdminServiceFactory ??

Thanks!

This may be because you don't have a connection string named IdentityDbContext

No, because the following code works:

public IdentityAdminManagerService()
      : base("IdentityDbContext")
{
}

But my goal is to write the following code:

public IdentityAdminManagerService(IDatabaseConfiguration databaseConfiguration)
      : base(databaseConfiguration.ConnectionString)
{
}

The IDatabaseConfiguration was registered in my Unity container. As the IdentityServer3 use Autofac for Dependency Injection, my registered dependencies could not resolved.

You could use the dependency resolver overload like this:

var dbConfiguration = new DatabaseConfiguration(); // either resolve it using DI or create an isntance of IDatabaseConfiguration
IdentityAdminServiceFactory factory;
factory.IdentityAdminService = new Registration<IIdentityAdminService>(resolver=> new IdentityAdminManagerService(dbConfiguration));

Thank you, That was the answer I was looking for 👍
