title: "nunit.framework.dll" could not be found
body: <p>I am following the NUnit tutorial <a href="http://www.nunit.org/index.php?p=quickStart&amp;r=2.4.1" rel="nofollow">here</a>. </p>
  
  <p>My source files live in the folder <code>C:\Users\Me\Documents\Visual Studio 2015\Projects\NUnitTest\NUnitTest</code>. My NUnit DLL lives in the folder <code>C:\Program Files (x86)\NUnit.org\framework\3.2.0.0\portable\nunit.framework.dll</code>. I am certain that these paths are correct. </p>
  
  <p>To compile the source file <code>AccountTest.cs</code> into a DLL, I ran the following commands:</p>
  
  <pre><code>cd C:\Users\Me\Documents\Visual Studio 2015\Projects\NUnitTest\NUnitTest
  C:\Users\Me\Documents\Visual Studio 2015\Projects\NUnitTest\NUnitTest&gt;csc /target:library /out:AccountTest.DLL /r:C:\Program Files (x86)\NUnit.org\framework\3.2.0.0\portable\nunit.framework.dll AccountTest.cs
  </code></pre>
  
  <p>However, I see these error messages:</p>
  
  <pre><code>error CS2001: Source file 'C:\Users\Me\Documents\Visual Studio 2015\Projects\N
  UnitTest\NUnitTest\Files' could not be found.
  error CS2001: Source file 'C:\Users\Me\Documents\Visual Studio 2015\Projects\N
  UnitTest\NUnitTest\(x86)\NUnit.org\framework\3.2.0.0\portable\nunit.framework.dl
  l' could not be found.
  </code></pre>
  
  <p>Any advice?</p>
  
  <p><strong>EDIT:</strong> I didn't forget to add a reference to NUnit inside of my solution. I also included the appropriate <code>using</code> statement.</p>
