title: The OutputPath property is not set for project TFS2012
body: <p>I have a build in our Team Foundation server which gives this warring:</p>
  
  <blockquote>
    <p>C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.Common.targets
    (610): The OutputPath property is not set for project
    'Plugin.DeploymentTool.csproj'.  Please check to make sure that you
    have specified a valid combination of Configuration and Platform for
    this project.  Configuration='Release'  Platform='x86'.  You may be
    seeing this message because you are trying to build a project without
    a solution file, and have specified a non-default Configuration or
    Platform that doesn't exist for this project.</p>

  <p>I can't find any solution or why i get this error. But then i look at the generated zip file, the Binary folder are empty. I have tried to use the x86, x64 and Any CPU, to se if there are are any difference, which there are not.</p>
  
  <p>If i look into the project file, it looks okay.</p>
  
  <pre><code>&lt;PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' "&gt;
      &lt;DebugSymbols&gt;true&lt;/DebugSymbols&gt;
