title: MSBuild Task for setting custom attribute in AssemblyInfo.cs
body: <p>Is there a MSBuild task for setting custom attribute in AssemblyInfo.cs?
  I found AssemblyInfo task but it seems that it cannot set custom attributes, only predefined ones. I'd like to set 3 custom properties I have added into this file.</p>
  
  <p>Any suggestion how to solve this?</p>
