The TypePx module adds properties and methods to the most commonly used types to make common tasks easier. Using these type extensions together can provide an enhanced syntax in PowerShell that is both easier to read and self- documenting. TypePx also provides commands to manage type accelerators. Type acceleration also contributes to making scripting easier and they help produce more readable scripts, particularly when using a library of .NET classes that belong to the same namespace.
