The remote server returned an unexpected response:(404)Not Found.

   I often get this error when Iam working on a silverlight app in visual studio 2008. Once I restart Vistal studio, it works fine.. Is this a bug? What should I do to get rid of this bug?

 Iam using a wcf service that is in the same web so there is no issue of the service is running

Are you accessing some services.Because i was also facing same problem when i was working with wcf services.

It was due to the fact that some times those services were not running and some times it was taking wrong port for them.

Thanks,

Try to check available of 2 files clientaccesspolicy.xml and crossdomain.xml and point detail binding method and accesspoint when you trying to call web-service:

 BasicHttpBinding httpBinding = new BasicHttpBinding(BasicHttpSecurityMode.None);
 EndpointAddress endpoint = new EndpointAddress(InfoMap2D.Common.SysConfig.GetInstance().ServiceMap);
 httpBinding.MaxReceivedMessageSize = 200000;
 myService1 = new Service1SoapClient(httpBinding, endpoint);

I am running into the same problem.

My app starts to run and then dies with this error:

Any idea what's going on?

Ditto.  I just busted out Silverlight 2 and VS 2008 to see if I could update my current ASP.NET site to use a silverlight control for login.

I got all the code working fine locally - referencing the System.Web.ApplicationServices.AuthenticationService. 

When I deployed it to the real web, the first thing I ran into was that the service reference in the Silverlight app has an invalid endpoint.  So I modified the XML file to be the actual URL on the web.

After I call AuthenticaionClient.LoginAsynch, my LoginCompleted handler gets a Error back in the result: The remote server returned an error: 404 NotFound.

I threw a clientaccesspolicy file on the server just in case but it sure looks to me like that would only come into play cross-domain -- and all this is running on the same web server.

I have exactly the same problem. Any idea ?

Try to put crossdomain.xml into your project

Re: Re: Re: The remote server returned an unexpected response:(404)Not Found.

What goes in the crossdomain.xml?

Re: Re: Re: The remote server returned an unexpected response:(404)Not Found.

1    
2    <!DOCTYPE cross-domain-policy 
3      SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
4    <cross-domain-policy>
5            <allow-access-from domain="*" />
6    </cross-domain-policy>

Re: Re: Re: The remote server returned an unexpected response:(404)Not Found.

And this goes in the web root at the same place as the "ClientAccessPolicy.xml"?

 Exactly
