 so, i have invoke the methods using "Method1Async() " here my Web method name is "Method1" ,

Now i this methods is goes to background process, but i call next web methods "Method2" at the time this method is wait for first "Method1" Completion


Here i am facing as like,  get the "Method1"  Status information Through the "Method2" At the time i cant get the information every 10 sec. i can get only after method "Method1" is completed ,
