This handy little trick allows you to find out all the types that are defined for a specific namespace. If, like me, you’re using PowerShell to interact with custom DLLs, quite often you have hundreds of types defined. This script (and its variations) allows you to narrow down the list a bit when you’re searching.

var $dll = [Reflection.Assembly]::LoadFrom("$pwd\your.dll")
$dll.GetExportedTypes() | ? {$_.Namespace -eq "Your.Namespace" } | select Name, Namespace
