A cmdlet extension is a method in PowerShell that adds new functionality to an existing cmdlet. Cmdlets are the fundamental commands in PowerShell, designed for specific tasks like managing files or processes. When a cmdlet extension is developed, it's not a standalone command but rather a set of methods that can be invoked in conjunction with a target cmdlet. This allows developers to enhance the capabilities of existing cmdlets without altering their original code.

These extensions are typically written in .NET languages and are compiled into assemblies. PowerShell then loads these assemblies and makes the extension methods available. The primary benefit of cmdlet extensions is their ability to extend the functionality of cmdlets in a modular and organized fashion. This promotes code reusability and allows for the creation of specialized tools that build upon the core PowerShell environment. For instance, an extension might add advanced error handling or data validation to a standard cmdlet. The exact implementation and availability of cmdlet extensions can vary depending on the PowerShell version and any third-party modules that might be in use. They are a powerful but less commonly discussed feature for customizing PowerShell behavior.
