title: Unsupported test framework error in NUnit
body: <p>I am using NUnit testing with Visual Studio 2013. We are using NUnitTestAdapter for integration of test run of NUnit with Visual Studio.</p>
  
  <p>Visual Studio 2013
  NUnit is version="3.0.1"
  NUnitTestAdapter version="2.0.0"
  .Net Framework 4.5.2</p>
  
  <p>All packages are latest &amp; installed from Nuget. There is no  build error.
  We are getting error in test result window:</p>
  
  <pre><code>Attempt to load assembly with unsupported test framework in  D:\JuniorAchievement\Git\jaums\JA.UMS.Tests\bin\Debug\JA.UMS.Tests.dll
  </code></pre>
  
  <p>while running or debugging test using Visual Studio Test Explorer.</p>

  <p>Test is able to run on one machine with same code on Visual Studio 2013 ultimate. We all other have Visual Studio 2013 professional version, although I doubt it has nothing to do with the problem.</p>
  
  <p>Please Help.</p>
  
  <p><strong>Update</strong></p>

  <p>Somehow both Adapter are available but with Nuget &amp; VS extension I can find only 
  NUnit3 Test Adapter.</p>
  
  <p>Installed NUnit3 Test Adapter from <a href="https://visualstudiogallery.msdn.microsoft.com/0da0f6bd-9bb6-4ae3-87a8-537788622f2d" rel="noreferrer">https://visualstudiogallery.msdn.microsoft.com/0da0f6bd-9bb6-4ae3-87a8-537788622f2d</a></p>
