Set Fully Resolved Assembly to Lightweight Example (C#)

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.
