If you receive objects from a call to Invoke-Command, they come back deserialized. These deserialized objects are missing the GetType method. GetType should be there on all objects, deserialized objects included (in which case I would expect it to tell me the objects are PSObjects).

+1 to Keith Hill's comment. Anything that inherits from System.Object should have GetType().

+1 on expecting these to implement gettype(). Just last week I was writing a script which needed to understand deserialized objects and I was surprised when gettype() didn't work.

In contrast to Kirk, though, my expectation was that the type would be Deserialized.Foo.Bar as shows up in some places, as opposed to just psobject.

Either would be better than nothing.

I expect *all* .NET objects to have a GetType() method! That's fundamental to .NET.

Use Get-Member to see if the object has a GetType method. If not, it is a PSObject that is representing an object that was deserialized from another session.
