title: Error debugging code in visual studio 2012 - Failed to initialize client proxy: could not connect to
body: <p>I am having Issues debugging unit tests in visual studio. I can run them fine from test explorer. The issue is that I cannot step into the code and debug. Also, I am able to debug other parts of the code that are not unit tests.</p>
  
  <p>When I right click on the test from test explorer and click debug I get a loading dialog saying "Loading symbols for vstest.executionengine.x86.exe from f:\biniaries\vset\mstestexecutor.x8g.csproj_1420192002\objr\x86". After a few more of these the test stops running and I get the following error displayed in the output window under "Tests". </p>
  
  <pre><code>  ------ Run test started ------
    Failed to initialize client proxy: could not connect to .
    ========== Run test finished: 0 run (0:01:05.45) ==========
  </code></pre>
  
  <p>I have tried the following:</p>
  
  <ul>
  <li>Set new directory for the "Cache symbols in this directory" setting.</li>
  <li>Reinstalled VS2012 with Update 3 </li>
  <li>Running with the safemode switch</li>
  <li>Ran the vs2012 repair tool</li>
  </ul>
