title: Passing Items to MSBuild Task
body: <p>I would like to use the "MSBuild" task in my target in order to build another project, while passing some items (with their metadata) from the current project to the project to be built.<br>
  While it's possible to pass properties using the Properties attribute or the AdditionalProperties Metadata, I couldn't find a way to pass Items.<br>
  A possible solution could be to write the items to a file and pass the filename as a property, but this would pass only the items, without their metadata.</p>
  
  <p>Any idea?</p>
  
  <p>Thanks.</p>
