title: Microsoft Fakes and Shims with nunit
body: <p>I'm trying to test userservice and I want to fake datetime using Fakes.ShimsContext like it was told on <a href="http://chrismay.org/category/testing/" rel="nofollow">this page</a></p>
  
  <p>On test execution I'm getting </p>
  
  <blockquote>
    <p>UnitTestIsolation instrumentation failed to initialize. Please restart
    Visual Studio and rerun this test</p>
  </blockquote>
  
  <p>Any difference is that I'm using nunit framework.</p>
  
  <p>Is there any issues I should be aware when using nunit with Microsoft Fakes and Shims?</p>
