Create Layer for Selected View Example (C#)

//----------------------------------------------------------------------------
// Preconditions:
// 1. Open a drawing of a part.
// 2. Add reference, Microsoft.VisualBasic, to the project.
// 3. Select a drawing view.
//
// Postconditions: Creates a layer for the selected view. To verify the creation
// of a layer for the selected view, click the Layer Properties tool on the
// Line Format toolbar. The newly created layer is selected in the
// Layers dialog box.
