如何在WPF应用程序中组合MVVM和依赖注入？

var builder = new ContainerBuilder();
builder.RegisterType<Repository>().As<IRepository>();
builder.RegisterType<ViewModel>();
var container = builder.Build();

public class ViewModelLocator
{
    private IContainer _container;

    public ViewModelLocator()
    {
        var builder = new ContainerBuilder();
        builder.RegisterType<Repository>().As<IRepository>();
        builder.RegisterType<ViewModel>();
        _container = builder.Build();
    }

    public ViewModel MainViewModel => _container.Resolve<ViewModel>();
}

   <local:ViewModelLocator />
</Window.DataContext>

public class ViewModel
{
    private IRepository _repository;

    public ViewModel(IRepository repository)
    {
        _repository = repository;
    }
}
