Last week I posted the Introduction to Service Bus Queuesen-USTelligent Evolution Platform Developer Build (Build: 5.6.50428.7875)http://blogs.msdn.com/b/appfabric/archive/2011/05/25/an-introduction-to-service-bus-topics.aspx#10232031Tue, 01 Nov 2011 11:46:35 GMT91d46819-8472-40ad-a661-2c78acb4018c:10232031Amit Shukla MSFT<p>Good One !!</p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=10232031" width="1" height="1">http://blogs.msdn.com/b/appfabric/archive/2011/05/25/an-introduction-to-service-bus-topics.aspx#10218333Thu, 29 Sep 2011 21:14:50 GMT91d46819-8472-40ad-a661-2c78acb4018c:10218333Karthik<p>Nice Post!</p> <p>Is it possible to specify additional metadata on a subscrption?</p> <p>I&#39;d like to be able to store information like who created the subscription etc...</p> <p>Also the management portal doesn&#39;t allow you to specify any filters.

We just haven&#39;t made that available, yet. SQL expressions are the canonical filter language in most pub/sub systems so we gave priority to that style.</p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=10174548" width="1" height="1">http://blogs.msdn.com/b/appfabric/archive/2011/05/25/an-introduction-to-service-bus-topics.aspx#10174545Tue, 14 Jun 2011 20:57:40 GMT91d46819-8472-40ad-a661-2c78acb4018c:10174545Mike Goodwin<p>Nice post. I love the way the AppFabric is developing!</p> <p>Interesting that you chose to use SQL-like expressions. Is there any reason why you didn&#39;t go for a lambda expression approach to take advantage of strong typing?</p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=10174545" width="1" height="1">
