Question

I’m doing some exercises with C# in the trial version of VS 2012. I want to execute a cmd command from a CS file. For this, I’ve tried Process.Start as well as System.Diagnostics.Process that are mentioned in these posts:

Run Command Prompt Commands

Execute CMD command from code

However, despite I added “using System.Diagnostics” and “using System.ComponentModel”, I’m still getting “The type or namespace name ‘Process’ does not exist in the namespace ‘System.Diagnostics’, missing assembly reference” error. ¿Any suggestion so I can i get rid of this error? Thanks in advance.

This usually happens when you have Target framework = .NET Framework Client Profile, but DLL you reference is from .NET Framework (full). Make sure you have System.dll in your references from valid framework.

I just did the same – created empty console application with the following code:

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.ComponentModel;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            var prc = Process.Start("explorer.exe");
        }
    }
}

Works perfectly fine for me.

Additional thing to check is Intellisense – when you start typing “System.Diagnostics.Proc”… – does it show you dropdown with “Process” there?

UPDATE:
Windows Store projects are based on different version of target .NET Framework – .NET for Windows Store apps, which does not support functionality you need.
