I am trying to use MDT from c# like I can already do with powershell when importing MicrosoftDeploymentToolkit.psd1. For example I can run the command Get-MDTPersistentDrive directly from powershell without problem.
But I can't find a way to do the same thing from c#, I tried to include directly the Microsoft.BDD.PSSnapIn.dll (which was basically what was doing "MicrosoftDeploymentToolkit.psd1") then I could access to the GetPersistent class but an error message informed me that I cannot directly invoke a PSCMDlet.
I then tried to use the PowerShell class
var ps = PowerShell.Create();
ps.AddScript(@"import-module C:\...\MicrosoftDeploymentToolkit.psd1");
ps.Invoke();
ps.AddCommand("Get-MDTPersistentDrive");
var result = ps.Invoke();
But I receive this exception
The term 'Get-MDTPersistentDrive' is not recognized as the name of a cmdlet, function, script file, or operable program
I then tried to do this
InitialSessionState initial = InitialSessionState.CreateDefault();
initial.ImportPSModule(new string[] { @"C:\...\MicrosoftDeploymentToolkit.psd1" });
Runspace runspace = RunspaceFactory.CreateRunspace(initial);
runspace.Open();
PowerShell ps = PowerShell.Create();
ps.Runspace = runspace;
ps.Commands.AddCommand("Get-MDTPersistentDrive");
var result= ps.Invoke();
and I receive the error
Object reference not set to an instance of an object
I'm really lost, I don't get what they mean with this error, If you could show me where I'm wrong, or a way to execute PSCmdlet from c# or even better directly how to control MDT that would be awesome.
