We recommend you start withen-USTelligent Evolution Platform Developer Build (Build: 5.6.50428.7875)http://blogs.msdn.com/b/clustering/archive/2010/03/30/9987135.aspx#10156717Thu, 21 Apr 2011 15:46:45 GMT91d46819-8472-40ad-a661-2c78acb4018c:10156717Kevin<p>Thanks for the informative series of posts.</p> <p>You mention that after calling Open, the resource should be offline. &nbsp;Let&#39;s say my resource is a service that supports named instances. &nbsp;How can I ensure the service is offline if I don&#39;t know its name? &nbsp;I assume I can store the service name as a private property, but can a user set this property prior to a call to Open? &nbsp;Implementing IWEExtendWizard sounded promising, but it&#39;s been dropped in Server 2008. &nbsp;What&#39;s the recommended way of handling this?</p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=10156717" width="1" height="1">
