HOWTO: csharp - powershell - call get-clusteredmailboxserverstatus with managed code.

// HOWTO: csharp - powershell - call get-clusteredmailboxserverstatus with managed code.
// Sample which calls get-clusteredmailboxserverstatus and returns a list of nodes.
//TODO:
//#1 - Create a C# winform application and add a button.
//#2 - Add namespace reference statements (using statements):
//      //Need for handing things like SecureString types...
//      using System.Security;
//      // For calling commandlets:
//      using System.Management.Automation;
//      using System.Management.Automation.Host;
//      using System.Management.Automation.Runspaces;
//      //General collection handling:
//      using System.Collections.Generic;
//      using System.Collections.ObjectModel;
// #3 - Set a eference to the "System.Management.Automation.dll"
//      This is installed by the Windows Powershell SDK.
//      OK, some articles say the files are here in some articles:
//          32bit:  C:\WINDOWS\SysWOW64\windowspowershell\v1.0
//          64bit:  C:\WINDOWS\system32\windowspowershell\v1.0
//      However, you will find it here after installing: 
//          C:\Program Files\Reference Assemblies\Microsoft\WindowsPowerShell\v1.0
