Assembly

An Assembly is a collection of types and resources that are built to work together and form a logical unit of functionality. In a ScriptoForm, assemblies are used to implement Windows forms and child controls and components. They can be referenced by using the Add-Type cmdlet, which lets you define a Microsoft .NET class in your PowerShell session available in the referenced assembly. You can then instantiate objects, by using the New-Object cmdlet, and use the objects just as you would use any .NET object.

Examples

Add-Type -AssemblyName System.Windows.Forms

# Other lesser used assemblies:
Add-Type -AssemblyName System.Windows.Forms.DataVisualization
Add-Type -AssemblyName System.Drawing
Add-Type -AssemblyName System.Data
Add-Type -AssemblyName System.Xml

Notes

An Assembly must be loaded prior to instantiating any form or control defined in it.
