Hello Lartik,
Please remove word static from your below method signature and give a try:
public static List<string> GetBankNames(string pre)

Hey it is the "static" issue.

If you have a web method as part of your Page class, it must be static.

If you've put a web method in an .asmx file to use across your application, it must not be static.
