Question

Shouldn’t this just work?

Interface

public interface IConfig : ISmtpConfig, IEventConfig

Binding

kernel.Bind<IConfig>().To<Config>();

Usage

public SmtpClient(ISmtpConfig config)

It complaints that it cant find any bindings for ISmtpConfig

Answer 1

The answer from anders is correct. This answer here follows up the comments from steven and anders. If you use the conventions extension there is a BindAllInterfaces(). This automagically binds all interfaces of the class. Here is an example:

kernel.Bind( x => x
    .FromThisAssembly() // 1
    .SelectAllClasses().InNamespaceOf<IConfig>() // 2
    .BindAllInterfaces() // 3
    .Configure(b => b.InSingletonScope())); // 4
