Web Service method name is not valid

Question

I get the following error \"Web Service method name is not valid\" when i try to call webmethod from javascript

System.InvalidOperationException: SaveBO

Answer 1

It was a silly mistake.

remove Static keyword from method declaration.

[WebMethod]
public string SaveBOAT(string Pid)
{        
     SessionManager.MemberID = Pid;
     return "";
}
