Access Exchange information without PowerShell?

Hello,

We have an application written in C#.NET 3.5.1 that queries the edition of Microsoft Exchange using PowerShell.

We have a problem now with Exchange 2013 that requires a newer version of PowerShell (and therefore .NET) to execute the Get-ExchangeServer cmdlet.

The cmdlets query the target Exchange server using WinRM under the hood.

1. Is it possible to bypass Powershell and query WinRM directly?
2. Is this supported / documented?

Many Thanks!

Dave
