title: 'CSC : error CS1902: Invalid option 'portable' for /debug; must be full or pdbonly'
body: <p>I get this error continuously on mac VS 7.4.3 when trying to run simple web form.</p>
  
  <pre><code>CSC : error CS1902: Invalid option 'portable' for /debug; must be full or pdbonly
  </code></pre>
  
  <p>I have tried manually updating .csproj file with:</p>
  
  <pre><code>&lt;DebugType&gt;portable&lt;/DebugType&gt;    
  </code></pre>
  
  <p>But did not help anything; I am understanding it's from package being window's / microsoft based; but have no idea how to fix to run with mac.</p>

  <p>I have also commented out all instances of 'portable' in the file above..  ?</p>
