Developing with PowerShell Classes: Here be Dragons
summary
Dives into concrete PowerShell 5 class gotchas with demos from a real project PoshBot showing what actually breaks and how to work around it: classes must live in the PSM1 or they won’t be exposed, using module exposes types but Import-Module and RequiredModules do not, module versioning and import semantics behave oddly, class file order affects inheritance, and verbose/debug streams and hidden properties have surprising behavior. Several pragmatic fixes are shown (build-time concatenation, factory functions, runtime checks) but many are kludges not clean fixes.
