"result" is neither 1 nor 2. It might help your debugging if you update your code

if(result==1)
{
strValue = "User exists";
}
else if(result==2)
{
strValue = "User doesn't exists";
}
else
{
strValue = "Error " + result.ToString() + " was returned";
}

If you are able to browse the service means it doesn't have hosting problem. Make sure that you are getting correct value in result variable. Just cross check database connection string :)

First of all i don't know why you are checking the else condition "else if(result==2)". I suggest if result == 1 then display user exist then else does not exist without any condition. Make sure you always return some value from WCF service instead of returning empty strings which will make it difficult to troubleshoot.

What i understand is clearly the result returned is neither 1 nor 2 so it is sending the empty result.

If you want to debug the WCF service hosted on IIS server then launch the WCF Test Client from the WCF project. Once the WCF Test client is launched go to File Menu and say "Add Service" then give the WCF service URL. This will give you the API's exposed from the WCF Service and then select the method you want to debug by providing the input values required.

Please let me know if you face any issue debugging, will help.

Let me know if this solved your problem.
