Porting to Windows 10 errors: "missing a using directive or an assembly reference"

Seems like an old circumstance but wondering why it's happening in Unity 5.2.3...
Much appreciated if someone give me some light on how to resolve!

Our environment: Unity project upgraded from 4.6.3 to 5.2.3 + Windows 10 + VS2015 Community.
Build Settings chose Windows Store and Universal 10 SDK.
Errors:
Drop in replacement for System.Timers.Timer

Some namespaces can't be used on the Universal Windows Platform. Eg: Windows.Network.Sockets instead of System.Net.Sockets or Windows.Data.XML instead of System.XML.

This means a lot of times you need to have two versions of some things, a Mono version or stub for the Unity Editor and a #if NETFX_CORE version for when it's being compiled with Microsoft's .NET.

 

This might help for the XML part of it. Unity made a (mostly) drop in replacement:

Hello!

I'm getting the same error as your first, that the type or namespace "Process" could not be found. Was there a way to resolve this? I looked at the link Garth-Smith posted, and I didn't see System.Diagnostics listed, which I'm assuming means I can't use that in Unity? Is there a way around this though so that I can still open an .exe from inside my unity build?
Thanks so much!

 

@Tomas1856 that's really good to know, I was unaware of that, thank you so much for your reply. I read through that page and the links it has listed, but I think I'm looking for something different than this? I don't want to have a program that's launched as the default handler for a file type. I want to be able to run a program from the command line from inside my unity application, and then use the text results that are generated. Is there a way to do that with association launching? Or would I need something different?

Thank you again for any help!

 

I looked into using the DLL, and that was exactly what I needed. Thanks so much for your help!!
