Silverlight 4.0: Unhandled Error in Silverlight Application[Async_ExceptionOccured]

2
votes

I am deploying my Silverlight 4.0 application in various operating system. In Windows 7 it works perfectly, however in Windows XP SP3, error pops. It says Unhandled Error in Silverlight Application [Async_ExceptionOccurred] Arguments: Debugging resource strings are unavailable. Often the key and arguments provide sufficient information to diagnose the problem. See http://go.microsoft.com/fwlink/?linkid=106663&Version=4.0.50524.0&File=System.dll&Key=Async_ExceptionOccurred....

What seems could be the problem?

Thanks

Not really much useful information to go on here. Note only is there no code but we don't even know what type async operation is being performed. - AnthonyWJones
By what is written I guess this the error is from the deployment server and this application works fine when debugging. So I bet the ServiceReference has hardcoded localhost:port/path in it, thats why it doesn't work on the development server. - Rumplin
@AnthonyWJones, the reason behind code is not displayed because the installer works in windows 7 but not in XP. - xscape
Installer? Please get your facts straight, we are trying to help, but you give us info that makes no sense - Rumplin

Go to the client bin folder and rename your .xap file to .zip. You should now be able to open the file up like any normal zip file. Locate the .clientconfig file and open it up in Notepad. Check that your endpoint addresses are set to a FQDN.

In your Silverlight project locate the ServiceReferences.ClientConfig file and open it.

in Silverlight 4 you can address your endpoints with .. like this:

 <endpoint address="../Services/Common.svc" binding="basicHttpBinding"
        bindingConfiguration="BasicHttpBinding" contract="Common.ICommon"
        name="BasicHttpBinding_ICommon" />
