title: wix wants an assembly manifest - I have one
body: <p>I have created a C# CustomActions project to use in wix to create an installer. All I have is the sample project and a sample wix project that references it. And I created an app.manifest in the C# project.</p>
  
  <p><a href="https://www.dropbox.com/s/auanpay6eh8ne85/WixTest.zip?dl=0" rel="nofollow noreferrer">Example simple program</a></p>
  
  <p>What I get is:</p>
