Has anyone tried setting up a webservice to communicate with silverlight (client side code) successfully? Mine runs fine in the virtual development server (VS 2008), but has problems on the webserver. Cheers!
I've got a similar issue (may be the same), below is my error message. Also go to http://nokolacom00.web701.discountasp.net/services/to see it. Any help is greatly appreciated! Maybe we have to run "ServiceModelreg -i in c:\Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation " in order to install WCF correctly? I had similar issue on my local box and fixed it with the above command. Please help!

Sorry, I just redeployed everything at /, and when trying to access the service: http://nokolacom00.web701.discountasp.net/ShockService.svc I get this: Server Error in '/' Application.

ok everything works for me now...i created a new web site in vs (New -> web site from solution, then selected WCF service), then created a custom factory for it, and added a silverlight link
i am getting the same error though my service has nothing to do with silverlight. i createdthe "WCF Application" in Visual Studio 2008 with dependency on .net 3.5. the WCF service works on my local machine but i can't get it to work on discountasp.net. i published my service to a new IIS application folder. when i browse to it i get... Cannot add duplicate collection entry of type 'add' with unique key attribute 'name' set to 'ScriptHandlerFactory' 134: <remove name="WebServiceHandlerFactory-Integrated"/> 135: <add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" 136: type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> you might be able to see the same error at http://www.timesupkidz.com/operations/service1.svc i have no idea how to fix this problem.
i deleted all the offending lines from the web.config. now i get... This collection already contains an address with scheme http
i then modified the web.config as follows, which seemed to fix the problem when it was deployed to discountasp but causes it to fail on my dev machine. i wish i didn't have to do any of this, esp when i don't understand what is going on. <system.serviceModel> <serviceHostingEnvironment> <add prefix="http://www.timesupkidz.com/operations" /> </baseAddressPrefixFilters>
