The first is to solve the problem of accessing Web Service Cross-origin access by SL.

Read the msdn and online materials, which are described in

  • Place a clientaccesspolicy. xml file in the root directory of the domain hosting the service to configure the service to allow cross-origin access.


      <?xml version="1.0" encoding="utf-8"?>
    <allow-from http-request-headers="SOAPAction">
    <domain uri="*"/>
    <resource path="/" include-subpaths="true"/>



  • Place a valid crossdomain. xml file in the root directory of the domain hosting the service. This file must mark the entire domain as public. Silverlight supports a subset of the crossdomain. xml architecture.


      <?xml version="1.0"?>
    <!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
    <allow-http-request-headers-from domain="*" headers="SOAPAction,Content-Type"/>



    However, I believe many friends still use Win XP as the development environment. Naturally, these two files will be placed in the same file as the web service. This will cause a system error.

    The correct method is to place the two files in the directory mapped to the "default website" of IIS.
