PowerShell - What available Assemblies from VisualBasic can be used?

I ran across an article showing that PowerShell is able to use VisualBasic Assemblies by adding

Add-Type -AssemblyName Microsoft.VisualBasic

So it got me curious which Assemblies from VisualBasic can be utilized, or if there is a way (through powershell) to list which ones are available to be used? 

Such as [Microsoft.VisualBasic.Interaction]::Inputbox("Testing Inputbox: ")

What other ones can be used, and is there a way to list them like you can with members - like when you use get-member?
