Discussion in 'Silverlight' started by punkouter, Nov 6, 2008.

  1. I have had all sorts of trouble getting something up and running. Some of it has to do with

    WCF error: "This collection already contains an address with scheme http"

    And others.. I have tried fixes but it never works. HELP.

    I have no problem getting it to run on my local IIS
     
  2. Ive created the absolute more simple silverlight app that calls a WCF service.. what is the small change that needs to be done???
