Simple Prism Bootstrapper

im currently porting my program to using Prism 6, it's a WPF application. So i installed Prism.Unity (6.1.1) which came with Prism.Wpf (6.1.0), Prism.Core (6.1.0), Unity (4.0.1) and CommonServiceLocator (1.3.0).

Then i came along those PRISM samples, but for the love of god i can't get it to run. Here's my Bootstrapper:

public class Bootstrapper : Prism.Unity.UnityBootstrapper
{
    /// <exception cref="ActivationException">If there are errors resolving the shell instance.</exception>
    protected override DependencyObject CreateShell()
    {
        return Container.Resolve<Shell>();
    }

    protected override void InitializeShell()
    {
        base.InitializeShell();

        Application.Current.MainWindow = (Window)this.Shell;
        Application.Current.MainWindow.Show();
    }

    protected override void ConfigureContainer()
    {
        base.ConfigureContainer();

        this.RegisterTypeIfMissing(typeof(IWorkRepository), typeof(WorkRepository), true);
    }
}

Unfortunately i can't start it. VS 2015 says it needs System.Runtime to run

return Container.Resolve<Shell>();

but once added the whole class is marked as error. If i start it directly i get the exception it couldn't load Microsoft.Practices.ServiceLocation. I'm wondering of the dependency since several posts (including ms) suggests to remove all Practices.*.

Help would be really appreciated, since i can't get it to run. :(

What usings do you use?

The whole bootstrapper can be as simple as this (created by the Prism-template):

using Microsoft.Practices.Unity;
using Prism.Unity;
using PrismUnityApp2.Views;
using System.Windows;

namespace PrismUnityApp2
{
    class Bootstrapper : UnityBootstrapper
    {
        protected override DependencyObject CreateShell()
        {
            return Container.Resolve<MainWindow>();
        }

        protected override void InitializeShell()
        {
            Application.Current.MainWindow.Show();
        }
    }
}

and System.Runtime isn't needed as reference. Probably you inadvertently use a namespace from that (instead of Microsoft.Practices.Unity where the Container.Resolve<> extension is).
