Using ASP.NET Session State in a Web Service

One of the most common challenges that Web developers encounter is maintaining state in the stateless world of HTTP. There have been a number of clever means used to get around the stateless issue, from reposting application data with each request, to using HTTP authentication to map requests to specific users, to using HTTP cookies to preserve the state of a series of requests. One particularly clever way of maintaining state that hides all the challenging work below is to simply use the Microsoft® ASP.NETSystem.Web.SessionState.HttpSessionState class. You can use the ASP.NET HttpSessionState class from a Web method just as you can from ASPX pages, but things work a little differently for Web methods.

Stop File Change Notification

I have added the following code in application start (Global.asax) to stop file change notifications, for root directory changes.

//FIX disable AppDomain restart when deleting subdirectory

//This code will turn off monitoring from the root website directory.

//Monitoring of Bin, App_Themes and other folders will still be operational, so updated DLLs will still auto deploy.

System.Reflection.PropertyInfo p = typeof(System.Web.HttpRuntime).GetProperty("FileChangesMonitor", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Static);

object o = p.GetValue(null, null);

System.Reflection.FieldInfo f = o.GetType().GetField("_dirMonSubdirs", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.IgnoreCase);

object monitor = f.GetValue(o);

System.Reflection.MethodInfo m = monitor.GetType().GetMethod("StopMonitoring", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);

m.Invoke(monitor, new object[] { });

Thank You and Happy Coding..... :)
