I'll perhaps write a sample on my blog if I find some time :)</p> ( Gill Cleeren) http://www.silverlightshow.net/items/The-duplex-story-looking-at-duplex-communication-in-Silverlight-4-Part-3-Using-Net.Tcp.aspx Mon, 02 Aug 2010 09:49:52 +0300 RE: The duplex story: looking at duplex communication in Silverlight 4 - Part 3: Using Net.Tcp http://www.silverlightshow.net/items/The-duplex-story-looking-at-duplex-communication-in-Silverlight-4-Part-3-Using-Net.Tcp.aspx#comment4088 <p>Great.. I got it working with the net.tcp.  Exactly what I am looking for.  I am curious though, you had mentioned in the part II, "In scenarios where the client needs to be updated because of changes in the state of the server side (for example a change in a database, a file change…), the best solution is working duplex."</p> <p>I have that scenario now where a third party application is updating our database.  When the database is updated, I would like for it to update our client (silverlight) of the changes.  Do you have an example of a database pushing changes to the silverlight client?</p> <p>Thanks.</p> ( alphapapalima) http://www.silverlightshow.net/items/The-duplex-story-looking-at-duplex-communication-in-Silverlight-4-Part-3-Using-Net.Tcp.aspx Fri, 30 Jul 2010 01:37:54 +0300
