How to create session enabled web service?

Problem: How to enable session in web service?

Solution:  By default, ASP.NET session support for each Web method is turned off. You need to add EnableSession=true property for the WebMethod attribute.


For example look at the following code snippet:



WebMethod(EnableSession=true)]
    public static int SessionCounter()
    {
        int counter=0;
        counter=Convert.ToInt32(Session["Counter"]);
        counter++;
        return counter;
    }

You need to confirm that session state is enabled in web config file.
