PowerShell 2.0 – Developer Essentials #1 – Initializing a Runspace with a Module

These days I'm incredibly busy both in my professional and private life, so I’ve not had a lot of time to construct the usual meaty posts I like to write. Instead I figured I could write a series of short – very short – posts centered around the little tricks that you would need to be an efficient developer when targeting PowerShell. Here's the first tip: how to create a Runspace and have one or more Module(s) preloaded. The RunspaceInvoke class is a handy wrapper that will do most of the plumbing for you if you just want to run scripts or commands. If you want to manually construct your own Pipeline instances then you must work with the Runspace class directly.

    InitialSessionState initial = InitialSessionState.CreateDefault();
    initialSession.ImportPSModule(new[] { modulePathOrModuleName1, ... });
    Runspace runspace = RunspaceFactory.CreateRunspace(initial);
    runspace.Open();
    RunspaceInvoke invoker = new RunspaceInvoke(runspace);
    Collection<PSObject> results = invoker.Invoke("...");

Have fun!
