Type Telerik.Reporting.Service provided as the Service attribute value in the ServiceHost directive could not be found

[Onaji Fernanda]

I have a project with Silverlight Reporting that works fine in dev. environment.
But in production i have this error on ReportViewer: 'An exception ocurred during the operation, making the result invalid. Check InnerException for exception details'.
My server is a virtual server.
I try to access the ReportService.svc, but have the  following error:
The type 'Telerik.Reporting.Service.ReportService, Telerik.Reporting.Service, Version=4.0.10.423, Culture=neutral, PublicKeyToken=a9d7983dfcc261be', provided as the Service attribute value in the ServiceHost directive could not be found
I´m not sure if is correct this response from ReportService.svc, in dev. enviroment the service is found fine.

I´m using Telerik Reporting Q1 2010, VS 2010 RTM,

I need to change something in configuration of server?

Thanks in advance.

Hi Onaji,

Invoking the Telerik Reporting service from the browser should yield the result from the attached screenshot.
Something that developers often forget is that Visual Studio has a built-in web server (Cassini) that is used when they work on applications locally. However when you deploy an application, you deploy it to IIS, which is an entirely separate domain and needs to be configured.
In this line of thoughts, have you tried hosting your application on your dev machine in IIS? From the information you've provided, most likely the problem is that you have not hosted the ReportService - please see:

• Embedding the Silverlight Viewer
• Hosting WCF Service in IIS

If you receive the same problem locally on IIS, you should be able to see more information about the error in the Output window in Visual Studio. About the service - set the includeExceptionDetailInFaults="true" attribute in your web.config for the service:

<serviceDebug includeExceptionDetailInFaults="true" />

for detailed error on what the problem is.
