@ManishGoswami but in that i will call a non static with a static method? and i hope there is nothing wrong with my registry line above aspx webform or i don't know why it's not working, — Shehroz Jalil, Jul 14 '16 at 13:59
@ManishGoswami is this error because of pageload? i have done nothing on my page load event — Shehroz Jalil, Jul 14 '16 at 14:35
i got this you are doing it so wrong you have copied code and u just placed it on page load. try this on your ASP web form click on Add new item in your project and add web service , will be named like WebService1.asmx and then place all the .cs class code there hope it will work, — Muhammad Mateen, Jul 16 '16 at 05:31
