I tried to deployed a SL project in IIS 7 by following the procedure by ESRI: 39169 - Deploy a Silverlight application to IIS 6.0 and 7.0 . After the deployment, I opened the project's htm on IE. The interface looks fine. But I run the query, a bunch of errors show up. Some of the errors are listed below:
Locator service failed: System.Security.SecurityException ---> System.Security.SecurityException: security error
at System.Net.BrowserHttpWebRequest.InternalEndGetResponse(IAsyncresult asyncResult)
at System.Net.BrowserHttpWebRequest ...
...
It appears it involves some security issue. What should do to solve these problems. Thanks.
