WebClient Class in build for Windows Store - Build Errors

Unity Engine
1

I’m building an app in unity (5.4.0f3) for the Windows Store platform (Universal 10 SDK).
I’ll be running it on hololens.

I am having an issue compiling my scripts and it appears to be due to the WebClient code that I am using.
The compile errors I am getting:
error CS0246: The type or namespace name ‘WebClient’ could not be found (are you missing a using directive or an assembly reference?)
The name ‘webClient’ does not exist in the current context

I have just started working with Unity but I believed that I could add a few directives around the code that uses the WebClient or declares a new WebClient so that it would still compile and be able to run on the hololens.

I found the “Platform dependent Compilation” page (Unity - Manual: Conditional compilation) which seemed to explain this.
I tried using a few of them (for example UNITY_WSA, UNITY_WSA_10_0 etc,) but no luck.
Any suggestions?

Did you get any follow up to this?

I’m also stuck finding a HTTP library that both (a) works with windows store, and (b) works in Unity’s old version of .NET
