Running Powershell Workflow from C#

Question

I'm trying to run this code:

    using (PowerShell PowerShellInstance = PowerShell.Create())
    {
        _outputCollection.DataAdded += outputCollection_DataAdded;
        PowerShellInstance.AddScript(@"workflow test { Write-Warning 'this is a warning'; }; test");
        IAsyncResult result = PowerShellInstance.BeginInvoke<PSObject, PSObject>(null, _outputCollection);
    }

But I get this error:

Windows PowerShell Workflow is not supported in a Windows PowerShe ll x86-based console. Open a Windows PowerShell x64-based console, and then try again.

How can I open a x64 based instance of Powershell from C#?

Here is a work around that doesn't involve trying to use RunspaceMode.CurrentRunspace (which is hard to use because getting the dll to work is tricky)

WSManConnectionInfo connectionInfo = new WSManConnectionInfo();
//Create and open a runspace.
Runspace runspace = RunspaceFactory.CreateRunspace(connectionInfo);
runspace.Open();
using (PowerShell PowerShellInstance = PowerShell.Create())
{
    _outputCollection.DataAdded += outputCollection_DataAdded;
     PowerShellInstance.AddScript(@"workflow test { Write-Warning 'this is a warning'; }; test");
     IAsyncResult result = PowerShellInstance.BeginInvoke<PSObject, PSObject>(null, _outputCollection);
}
runspace.Close();
