I don't know where I am wrong, I have tried the answer of the following links but nothing works for me:

• Link1
• Link2

If any one can help...

Answer 1

The error denotes that the IIS is not able to find the type mobile.Service . There could be many reasons why it is not able to find the type. I suggest you to specify the assembly name also in the service attribute.

Also, you can check whether the assembly really contains the type by using ILDasm .

Update

Try

<%@ ServiceHost Language="C#" Debug="true" Service="APIService.Service" CodeBehind="Service.svc.cs" %>
