SilverLight Service Deployment <p>I've written a silverlight app with a simple wcf service. Runs great on my computer, when I publish it to my web account it no longer works with the service. I tried editing the clintconfig file to set the endpoint to the new location, that did not fix it. So I downloaded this simple SilverLight App with WCF example setup for deploying, and it also works on my personal machine, but not when I publish it to my domain. My account supports asp.net, wcf, etc.. The link to the example I downloaded: <a href="http://www.codeproject.com/Articles/152778/Deploying-Silverlight-with-WCF-Services" rel="nofollow">http://www.codeproject.com/Articles/152778/Deploying-Silverlight-with-WCF-Services</a></p> <p>I'm new to this, so I'm wondering if this is something that should work without additional work, or if I'm missing something. I'm not getting any errors, I'm just not getting the message displayed on the screen from the service.</p> <p>Added following after Hatchets Comment: I'm trying to figure out how to find a error message. So far the only way I know it's not working is I don't see the message that is returned from the service. SilverLight displays the returned message, "Hello from My WCF Service". I see it on my machine, but not when I publish it to my domain. The app I downloaded, if I understand it right, is setup to work without having to change the endpoint address, but i'm so new to this, I've not figured out what i'm missing yet. Thanks.</p> <p>Added after comments below:</p> <p>I grabed fiddler, and after i added the tag, i was able to see an error in fiddler, and when browsing to the .svc file.
