Answer 1

1) not reflecting HttpContext in class file ?

Answer:-Most of the time when using this syntax in class file is not working we have to add reference then it work in class file

example using system.web write this syntax in class file

System.Web.HttpContext(HttpContext is not reflecting )

after that i add refrence system web than it reflect

Answer 2

I got this problem a couple of times and done different things to fix it. When I got it this time all I did to stop getting "unable to connect to asp..." error, was rename the web app folder directory from xpCal to xpCal2. I also tried moving the web app directory to a different directory from C:users\<me>\desktop\ to C:\users\<me>\desktop\new folder and it also worked.

I don't know why it worked, does VS 2010 keep information about web apps seperate from web apps folder.

Answer 3

My solution was to turn off Internet Connection Sharing on my wireless adapter, after which it immediately worked. I made no other change. I suspect ICS's DHCP server was interfering.

Answer 4

In my case, when I had the ASP.NET Development Server crash, one thing that worked was to change the port for the project.

I suspect what happened was when the web server crashed it did not release a lock on the port. Even though it was not running in Task Manager, something was blocking a new instance of the web server from starting again on the original port. Changing the port was a decent enough work around. I could have rebooted, but who has time for that, right?

Details: Windows 7 x64, VS2010, .NET Framework 4.0, ASP.NET web site using the built in web server to VS2010.

BTW, I would be a little cautious with replacing the WebDev.WebServerServer.EXE as suggested in other posts. If that file has been corrupted then you have bigger problems with your OS.

Answer 5

Here are the steps

1. 'Website' Menu in your visual studio ide.
2. select 'Start Options'
3. enable 'Use Custom Server' radio button.
4. Enter any URL you desire similar to 'http://localhost:8010/MyApp'

Note1: you can use any port number not only '8010' but not designated port numbers like 8080(tcpip),25(smtp),21(ftp) etc.,

Note2: you can use any name not only 'MyApp'

This solution works for sure unless your WebDev.Webserver.exe is physically corrupted.

Answer 6

I had this problem with VS 2010, and it was as simple as terminating the "WebDev.WebServer40.EXE" process. Although the icon was no longer showing in the system tray, the process was still running.
