title: Not able to use XUnit for unit tests in ASP.NET VNext and Visual Studio 2015 RC
body: <p>I created a a Visual Studio 2015 RC solution as follows:</p>
  
  <pre><code>Project
    global.json
  Source
    MvcProject
    MvcProject.Test
  </code></pre>
  
  <p>MvcProject.Test is a class library where I created a Test.</p>
  
  <p>The global.json file has the following:</p>
  
  <pre><code>{
    "projects": [ "Source" ],
    "sdk": {
      "version": "1.0.0-beta4"
    }
  }    
  </code></pre>
  
  <p>And project.json in MvcProject.Test is:</p>
  
  <pre><code>{
    "compilationOptions": {
      "warningsAsErrors": true
    },
    "dependencies": {
      "Microsoft.AspNet.Mvc": "6.0.0-*",
      "xunit.runner.aspnet": "2.0.0-aspnet-*"
    },
    "commands": {
      "test": "xunit.runner.aspnet"
    },
    "frameworks": {
      "dnx451": {
        "dependencies": {
          "Moq": "4.2.1506.2016"
        }
      }
    }
  }
  </code></pre>
  
  <p>I then created a simple test:</p>
  
  <pre><code>using Xunit;
  
  namespace MvcProject.Test {
    public class FirstTests {
  
      [Fact]
      public void HelloTest() {
        Assert.Equal(2, 2);
      }
  
    }
  }
  </code></pre>
  
  <p>When I build the solition I get the error:</p>
  
  <pre><code>The type or namespace name 'Fact' could not be found (are you missing a using directive or an assembly reference?)  MvcProject.Test.DNX 4.5.1   
  
  The name 'Assert' does not exist in the current context Bityond.Test.DNX 4.5.1  
  </code></pre>
  
  <p>What am I missing in my configuration?</p>
