部署的WCF Silverlight应用程序返回404错误

Question

I have a Silverlight 5 Web Application that I host in IIS 8. I can run my application fine in VS 2013 but on Deploying to a Windows 2012 server running IIS 8, my app fails to run. Fiddler gives me the following: Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

My Web.config file is shown below:

Can someone tell me why a previously configured Win 2012 server does not now load the deployed application when I can still run from VS 2013? Or is there a way to get Fiddler to give a more detailed error?

I set Tracing on, but the log does not give any better clues.

Thanks.

Chances are you have RIA Services installed on your development machine but it is not installed on the server.

You have two choices:

1. Remember to install RIA Services on each server you deploy to

2. Add the RIAServices.Server NuGet package to your *.Web project. This will add private local copies of the RIAServices dll to your solution.
