How to check whether the NetworkService is added in VMM or not

In my C# application, I want to check if my NetworkService is added in VMM or not.

For this I am currently creating an instance of runspace and calling the “Get-SCNetworkService”.

But it is taking more than expected time (>4 seconds).

Is there any better way to check whether the NetworkService is added in VMM or not?

Hope anyone can give me a solution for that. 

Thanks in advance,
