Call two web service methods simultaneously(parallel)

Hello All.......

I am new in .Net development..........

I want to call two web service methods simultaneously(parallel) using c# code from the application, web service is built as a separate application. In my application, one web service method should get called & it is not needed to wait for the response, then another service method should get called & it is not needed to wait for the response, but after calling both of these service methods, I need to wait for the respond for first method & as per the result I need to proceed ahead, what is the best way to perform this?

 

Thanks in advance.

Regards
