Why do PostSharp, and MSTest fail to build together in VS2013? - visual-studio-2013

Question

I am exploring PostSharp. I ran in to an early snag I don't understand. I am hoping for insight.
I have VS 2013 12.0.3051.00 Update 2. I used NuGet to install PostSharp 3.1.43.0. I also use Resharper 8.2.1 and I have dotMemory 4.0 installed.
I implemented the first tutorial, at http://www.postsharp.net/aspects/getting-started?utm_source=vsx&utm_medium=app&utm_campaign=Learn. This behaves as expected. I do some refactoring. First, I extract the aspects to a library.
namespace AspectImplementations
{
using System;
using System.Diagnostics;
using PostSharp.Aspects;
[Serializable]
public sealed class TraceAttribute : OnMethodBoundaryAspect
{
/// <summary>
/// Initializes a new instance of the <see cref="TraceAttribute" /> class.
/// </summary>
/// <remarks>
/// http://www.postsharp.net/aspects/getting-started?utm_source=vsx&utm_medium=app&utm_campaign=Learn
/// </remarks>
public TraceAttribute(string category)
{
Category = category;
}
public string Category { get; private set; }
#region Overrides of OnMethodBoundaryAspect
public override void OnEntry(MethodExecutionArgs args)
{
Trace.WriteLine(
string.Format(
"Entering {0}.{1}.",
args.Method.DeclaringType.Name, args.Method.Name,
Category));
}
public override void OnExit(MethodExecutionArgs args)
{
Trace.WriteLine(
string.Format(
"Leaving {0}.{1}.",
args.Method.DeclaringType.Name, args.Method.Name,
Category));
}
#endregion
}
}
I compile the project and run it and get expected behavior.
Next, I factor out the methods attibuted with the aspects to their own library.
namespace Conversation
{
using System;
using AspectImplementations;
public class Greetings
{
[Trace("Hi")]
public void SayHello()
{
Console.WriteLine("Hello, PostSharp");
}
[Trace("Bye")]
public void SayGoodBye()
{
Console.WriteLine("Goodbye, PostSharp");
}
}
}
I compile the code, and ignore the warning that PostSharp isn't needed in HelloPostSharp, anymore, run the app, and it behaves as expected.
Now I want to add some unit tests. MSTest works for me. This is where my trouble starts.
namespace TestConversation
{
using Conversation;
using Microsoft.VisualStudio.TestTools.UnitTesting;
[TestClass]
public class TestGreetings
{
[TestMethod]
public void TestCtor()
{
Greetings talker = new Greetings();
Assert.IsNotNull(talker);
}
[TestMethod]
public void TestSayHelloNotExceptional()
{
Greetings talker = new Greetings();
talker.SayHello();
}
[TestMethod]
public void TestSayGoodByeNotExceptional()
{
Greetings talker = new Greetings();
talker.SayGoodBye();
}
}
}
When I compile this, I get a dialog that suggests I need to add dependencies to PostSharp. I hit the OK button and let it add stuff. I get a build failure. I put "SkipPostSharp" in the HelloPostSharp project, where Main is. Still won't build. My Build output looks like
1>------ Rebuild All started: Project: AspectImplementations, Configuration: Debug Any CPU ------

My error list is empty. 0 Errors, 0 Warnings, 0 Messages.
Apparently, there is something I am not understanding about how to use unit testing with PostSharp. What am I missing?

Reboot to get the current assemblies in RAM
