Why

I need to to activate a feature in PowerShell and specify some properties. Simple? Yes. Possible? No. In the default Enable-SPFeature cmdlet you can’t specify any properties:

Enable-SPFeature –Identity "b5eef7d1-f46f-44d1-b53e-410f62032846" -URL http://dev

We can of course easily add properties when activating features in onet.xml:

<!-- Publishing Resources -->
<Feature ID="AEBC918D-B20F-4a11-A1DB-9ED84D79C87E">
  <Properties xmlns="http://schemas.microsoft.com/sharepoint/">
    <Property Key="AllowRss" Value="false" />
    <Property Key="SimplePublishing" Value="false" />
  </Properties>
</Feature>

So I went to SharePoint StackExchange and asked the question. Then I realized: the standard Sharepoin API doesn’t support this neither. The methods of SPFeatureCollection which have SPFeatureProperties as parameter are internal. So the only way is to use Reflection like Hristo Pavlov (2008) and Yaroslav Pentsarsky (2010) suggest. So why not to try to create a cmdlet?
