Debugging - Step into PowerShell Script Executed via API

Question

I'm using System.Management.Automation.PowerShell to programmatically execute a PowerShell script from C# application. The PowerShell script loads a .Net dll which it uses to perform its activities.

var script = "Add-Type -Path 'MyLibrary.dll'; ....";

using (var powershell = PowerShell.Create()) {
    powershell.AddScript(script);

    powershell.Invoke();
}

Is it possible to somehow connect Visual Studio's debugger to the PowerShell object instance so that the debugger can seamlessly step from the C# application into the PowerShell script and from that script into MyLibrary.dll (assuming I have symbols for the dll)?

Edit: Based on the below, it appears that there may not be a way to seamlessly flow debugging in Visual Studio from C# to PowerShell. However, it is possible to use VS to debug the C# code that launches and that is launched by PowerShell.

do you mean that you want to use the Windows PowerShell Debugger API like this sample? code.msdn.microsoft.com/windowsapps/Windows-PowerShell-f5c03f2d. To debug the dll file, you could think about using the custom helper class: stackoverflow.com/questions/8062407/… — Jack Zhai

@JackZhai-MSFT, thanks for those helpful links! Using System.Diagnostics.Debugger.Launch(); (mentioned in the second link) allowed me to debug the .Net code called by PowerShell in Visual Studio. I was hoping that there was a way to do the same with the PowerShell script itself, but oh well. :-) — Ben Gribaudo

@JackZhai-MSFT, would you mind turning your comment (at least the part pertaining to System.Diagnostics.Debugger.Launch();) into an answer so that I can accept it. :-) — Ben Gribaudo

You could debug the dll file by calling the following in your helper class:

System.Diagnostics.Debugger.Launch();
