Experiencing "DEP3000" error when trying to run WinRT unit tests

Question

I am experience this strange error trying to run unit tests for WinRT from Visual Studio 2012.

Error: DEP3000: Attempts to stop the application failed. This may cause the deployment to fail. App Packages may only be shutdown as part of a Visual Studio build operation

I don't understand at all what that could mean? I've tried restarting my computer and reinstalling developer license. How I reproduce it is I just create a new empty unit test project from the Visual Studio template. I don't touch the project at all. But, when I try to do Run Tests on it, it just says pending for a a while and then spits out that error

How do I fix this?

Specs: Windows 8 Enterprise 64bit, Visual Studio 2012 with Update 2

Also, I've seen this question about VS2012RC, but the answer doesn't seem to apply. I've tried every configuration of this there is and nothing works past this error

Use Task Manager, Details tab. See if you can kill the running instance of the unit test runner. — Hans Passant, May 04 '13 at 00:11

I had same problem when I applied VS upgrade2 AND used Resharper 7.1.1 to run the unittests. Turns out you need to upgrade Resharper to 7.1.3 -- or run the tests with the VS test explorer.

You can just try using XUnits App: https://channel9.msdn.com/Shows/demooftheday/xunit-in-uwp

With this, test will run on XUnit's test app, not in VS Test Explorer.

In my unit test project's project.json

 {   
"dependencies": {
        "Microsoft.NETCore.UniversalWindowsPlatform": "5.1.0",
        "xunit": "2.1.0",
        "xunit.runner.devices": "2.1.0"   },   "frameworks": {
        "uap10.0": { }   },   "runtimes": {
        "win10-arm": { },
        "win10-arm-aot": { },
        "win10-x86": { },
        "win10-x86-aot": { },
        "win10-x64": { },
        "win10-x64-aot": { }   } 
}

Then go to the XAML file in the unit test project named UnitTestapp.xaml and change it to

<ui:RunnerApplication
    x:Class="UnitTestProject1.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:UnitTestProject1"
    xmlns:ui="using:Xunit.Runners.UI"
    RequestedTheme="Light">
</ui:RunnerApplication>

And of course, in the code behind:

  sealed partial class App : RunnerApplication
  {
    protected override void OnInitializeRunner()
    {
      AddTestAssembly(GetType().GetTypeInfo().Assembly);
      InitializeRunner();
    }
    partial void InitializeRunner();
  }
