Set Fully Resolved Assembly to Lightweight Example (VB.NET)

This example shows how to set a fully resolved assembly to lightweight.

' Preconditions:
' 1. Open a fully resolved assembly document.
' 2. Open the Immediate window.
' Postconditions:
' 1. Sets all assembly components to lightweight.
' 2. Examine the Immediate window and FeatureManager design tree.
