connection string dependancy injection identity server v3

Question

I am using Thinktecture Identity Server V3 and having issues working out how to make the dependancy registration use different connection strings for 2 different repositories. See code below;

options.Factory.Register(Registration.RegisterType<IRepository<ScopeWrapper>>(typeof(MongoRepository<ScopeWrapper>)));
options.Factory.Register(Registration.RegisterType<IRepository<User>>(typeof(MongoRepository<User>)));

Thanks,

Ed
