Did you look at the server logs like the error message suggested? — Tim, Feb 19 '14 at 00:06
When you host Service on IIS, are you sure that you are hosting it correctly? Can you browse the service on IIS? — Faizan Mubasher, Feb 19 '14 at 04:56
exacly can you browse: http://localhost/MyService/Quiz/QuizServ.svc? Have a look in the windows event viwer (http://windows.microsoft.com/en-us/windows/open-event-viewer#1TC=windows-7) — Jocke, Feb 19 '14 at 06:23
Note: In the future, please post the **text** of the error message and stack trace, not a screenshot, as screenshots can be incredibly hard to read. In any event, the issue is with the account your service is running under - it doesn't have rights to login to the database. Either assign rights to that account, or better yet use a dedicated account to login and either run the app pool under it (with integrated security=true) or use the account name and password in the connection string. — Tim, Feb 19 '14 at 16:26

The database was causing an error. I have found the solution. what we need to do? We need to add a login to SQL Server for IIS APPPOOL\ASP.NET v4.0 and grant permissions to the database.

In SQL Server Management, under the server, expand Security, then right click the Logins and select "New Login...".

In the New Login dialog, enter the app pool as the login name and click "OK"

enter image description here now right click the login, select properties and then click on the User Mapping Option. Click the appropriate DATABASE and check the properties roles. And we are done :).

hope you good luck. Thanks

Possible solutions would be,

(i)Just ensure all your property are public.

(ii)To So see more details about the issue, you need to includeexceptiondetailInfaults attribute to true in servicedebug tag.

<servicebehaviors>
        <behavior name="myServiceBehavior">
          <servicedebug includeexceptiondetailinfaults="true" />
        </behavior>
</servicebehaviors>

(iii)Remove the Enum types (or use their suggested work-around and use a wrapper around the enum properties) and this should go away.

(iv)Copy the connection strings from the class library app.config to the web project web.config If you are using a class library and a web project,

Why to remove Enum types? – Faizan Mubasher Feb 19 '14 at 04:57
It's recommended to avoid enums in webservices because they create compatible problems. – Sajeetharan Feb 19 '14 at 05:00
Can you share a link? – Faizan Mubasher Feb 19 '14 at 05:00

Well then, he haven't pasted code, but still the problem he is posing is not related to enum, moreover, REST services return response in JSON/XML. So, no worried of enum. – Faizan Mubasher Feb 19 '14 at 05:23
thanks for your response. well I have searched alot but didn't find any solution. I think there is something wrong with my Database connection. I commented database connection and created an object with predefined values and it's work like a charm. – M A. Feb 19 '14 at 10:50
