I have run into an issue that when my web application's web.config compilation debug is set to true I am getting a vulnerability error on a security scan.

<compilation debug="true" targetFramework="4.0">

What I want to determine is if there is a way to have some type of web.config conditional block change the debug setting to use the correct value on debug builds and release builds. I have read that setting the property in each web page itself will do this and don't know if this is in fact true and are there any problems with this?

        public string GetAttributeKey(string attribute)
        {
            string qry = "SELECT ws_attribute_key FROM webservice_attributes WHERE ws_attribute = @attribute";

            QueryContainer Instance = new QueryContainer(qry);

            MyParam myParam = new MyParam();

            myParam.SqlParam = new SqlParameter("@attribute", Instance.AddParameterType(_DbTypes._string));

            myParam.SqlParam.Value = attribute;

            Instance.parameterList.Add(myParam);

            object key = ExecuteScaler(Instance);

            return Convert.ToString(key);
        }

What is difference between Eval() and Bind() Method???

Hai All, 
I am having two methods in a single service below. I will host this service in IIS. I will be having only one service URL. Client will consume this service by creating the proxy class as usual. But Mehod1 should only be displayed to Client A,  Mehod2 should only be displayed to Client B. How can I overcome this scenario?.. Can you please clarify my doubt..? Thanks in Advance

namespace serviceHide
{
    [ServiceContract]
    interface IServiceHide
    {
        [OperationContract]
        string Method1(string id); //This method should be displayed to Client A only

        [OperationContract]
        string Method2(string id); //This method should be displayed to Client B only

    }
}
