depedency injection to inject service in view model mvvm?

can some one help me?

Answer 1

It is based on IoC container you using. If you are using PRISM, you need to register the service contract and concrete type in bootstrapper.

    protected override void ConfigureContainer()
    {
        this.container.RegisterType<IMyService, MyService>();
    }

The registered contracts will be injected through constructor in your viewmodel.

    public MyViewModel(IMyService myService)
    {
    }

The life time of dependencies can also be controlled using LifeTime Managers. More information on that,
