The Web application could not be found

Question

Hello,
I have a machine that has s share point portal .
I create WCF on the same machine and set it on IIS and the identity of application pool is the administrator of machine 
          PlatformTarget : 64 bit ,  Framework : .net 4.5
I have added sharepoint.dll as refrenece in WCF project.
The identity 
I have a method on the WCF :
          public void Test(string siteCollectionURL)
                SPSite siteCollection = new SPSite(siteCollectionURL);
When I call this method , I get the following Error :
         The Web application at http://[servername]:9090/sites/Dhofar could not be found. Verify that you have typed the      URL correctly. If the URL should be serving existing content, the system administrator may
need to add a new request URL mapping to the intended application.
Iam sure the url is correct  . So how can I solve it
