"SERVER LOG after includeexceptiondetailInfaults attribute value to true"

I'ms sure that database is causing the error and you can view the picture of server log below

Answer 1

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"

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,
