Missing reference to System.Diagnostics.Process

Question

I have a app that I am building to shut down a computer

I tried using using System.Management; but it tells me to add a reference, No such thing in the add reference list I tried using this code but the proccess has a red squigly

System.Diagnostics.Process.Start("Shutdown", "-s -t 10");

Any ideas on how to shut down?

I cannot find the System.Management.dll ? how do i install it ? — user1264626, Aug 07 '12 at 12:25
Your code above should work. The only reason I could think it has the squiggly is if you do not have a reference to System.dll where Process is defined. — Justin Harvey, Aug 07 '12 at 12:27
You say "red squiggly," but what error does that represent? There will be a compiler error when you build... — Dan Puzey, Aug 07 '12 at 12:30
What kind of shutdown do you want? A user cancelable countdown, or a plain shutdown? — CodesInChaos, Aug 07 '12 at 12:35

There's one simple explanation for a mystifying problem like this: you are using the Portable Class Libraries or have selected the ".NET for Metro style apps" platform target. Which does not permit using the Process class, Metro apps operate in a sandbox that disables many standard .NET features. Starting another process or shutting down the OS is not permitted, only the user can do that.

You'll have to give up on Metro if this is important to you, your app needs to run as a desktop app. And won't run on a slate that boots Win8.

And this is why today we dont see metro apps – user1264626 Apr 28 '23 at 12:58 — user1264626, Apr 28 '23 at 12:58

I ended up

upgrading to the latest Visual Studio 2015 SP3,
running Scott Smith's upgrade command using powershell,
```
powershell dnvm upgrade -r coreclr
```

creating a console project anew from Visual Studio.

After adding more packages required to resolve the standard classes I observed this global.json,

{
  "projects": [ "src", "test" ],
  "sdk": {
    "version": "1.0.0-preview2-003131"
  }
}

and this project.json,

{
  "version": "1.0.0-*",
  "buildOptions": {
    "emitEntryPoint": true
  },

  "dependencies": {
    "Microsoft.NETCore.App": {
      "type": "platform",
      "version": "1.0.1"
    },
    "system.diagnostics.textwritertracelistener": "4.0.0-beta-23123",
    "System.Diagnostics.TraceSource": "4.0.0",
    "System.IO": "4.1.0"
  },

  "frameworks": {
    "netcoreapp1.0": {
      "imports": "dnxcore50"
    }
  }
}
