title: Not able to use package in version 4.6.1 in ASP.NET Core RC2
body: <p>I created a ASP.NET Core RC2 class library and on project.json I have:</p>
  
  <pre><code>"frameworks": {
    "net461": { },
    "netcoreapp1.0": {
      "dependencies": {
        "Microsoft.NETCore.App": {
          "type": "platform",
          "version": "1.0.0-rc2-3002702"
        }
      },
      "imports": [
        "dotnet5.6",
        "dnxcore50",
        "portable-net45+win8"
      ]
    }
  }
  </code></pre>
  
  <p>I used it on an ASP.Net Core RC2 web application which project.json has:</p>
  
  <pre><code>"dependencies": {
    "Microsoft.AspNetCore.Mvc": "1.0.0-rc2-final",
    "TestLibrary": "1.0.0",
  },
  
  "frameworks": {
    "net461": { }
  },
  </code></pre>
  
  <p>NOTE: I omitted the other dependencies for sake of simplicity.</p>
  
  <p>I get the following error when trying to restore the Web Project:</p>
  
  <pre><code>The dependency TestLibrary 1.0.0 does not support framework .NETFramework,Version=v4.6.1.   
  </code></pre>
  
  <p>What am I missing?</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>I changed my TestLibrary configuration to:</p>
  
  <pre><code>"dependencies": {
    "NETStandard.Library": "1.5.0-rc2-24027",
  },
  
  "frameworks": {
    "netstandard1.5": {
      "imports": [
        "dnxcore50",
        "portable-net452+win81"
      ]
    }
  }
  </code></pre>
  
  <p>But I have a class library project name TestLibraryTests with tests:</p>
  
  <pre><code>"testRunner": "xunit",
  
  "dependencies": {
    "NETStandard.Library": "1.5.0-rc2-24027",
    "xunit": "2.2.0-beta1-build3239",
    "dotnet-test-xunit": "1.0.0-rc2-build10015",
    "TestLibrary": "1.0.0"
  },
  
  "frameworks": {
    "netstandard1.5": {
      "imports": [
        "dnxcore50",
        "portable-net452+win81"
      ]
    }
  }   
  </code></pre>
  
  <p>But now I get the error:</p>
  
  <pre><code>Package dotnet-test-xunit 1.0.0-rc2-build10015 is not compatible with netstandard1.5 (.NETStandard,Version=v1.5). Package dotnet-test-xunit 1.0.0-rc2-build10015 supports:
    - net451 (.NETFramework,Version=v4.5.1)
    - netcoreapp1.0 (.NETCoreApp,Version=v1.0)
  One or more packages are incompatible with .NETStandard,Version=v1.5.
  </code></pre>
  
  <p>What am I missing? I can't use XUnit with RC2?</p>
