title: Xamarin Visual Studio Error MSB4064 and MSB4063
body: <p>I get the error after creating a new blank Xamarin project. As soon as the project is generated I get the errors:</p>
  <blockquote>
  <p>Warning    IDE0006 Error encountered while loading the project. Some project features, such as full solution analysis for the failed project and projects that depend on it, have been disabled.   Droid2      1   Active</p>
  <p>Warning        The &quot;ChecksumAlgorithm&quot; parameter is not supported by the &quot;Csc&quot; task. Verify the parameter exists on the task, and it is a settable public instance property.   Droid2</p>
  <p>Warning        The &quot;Csc&quot; task could not be initialized with its input parameters.  Droid2</p>
  </blockquote>
  <p>I've tried several times uninstalling Xamarin and reinstalling to no avail.</p>
  <p>The build log file is too big to add in its entirety so I just added the last bit. (30000 char limit)</p>
