title: TFS 2010 Build Definition: MSBuild Arguments seems to be ignored
body: <p>I am trying to create a package after a build in TFS 2010.</p>
  
  <p>When I launch the following command on my computer:</p>
  
  <pre><code> MSBuild.exe Fenicorp.Front.Web.FunnyApplication.sln 
   /p:DeployOnBuild=true;DeployTarget=Package
  </code></pre>
  
  <p>the solution is compiled and there is a package inside the obj folder.</p>
  
  <p>However, when I specify </p>
  
  <pre><code> /p:DeployOnBuild=true;DeployTarget=Package 
  </code></pre>
  
  <p>as MSBuild Arguments in a Build Definition and queue a new build, there is no package in my drop folder. Moreover the build status is Successfull, as if everything is fine.</p>
