Notice how each subclass implements TurboBoost() using the Windows Form’s MessageBox

class, which is defined in the System.Windows.Forms.dll assembly. For your assembly to make use of

the types defined within this external assembly, the CarLibrary project must set a reference to this

binary via the Add Reference dialog box (see Figure 15-7), which you can access through the Visual

Studio Project ➤ Add Reference menu selection.

Figure 15-7.

Referencing external .NET assemblies begins here.

It is really important to understand that the assemblies displayed in the .NET tab of the Add

Reference dialog box do not represent each and every assembly on your machine. The Add Refer-

ence dialog box will 

not display your custom assemblies, and it does not display all assemblies

located in the GAC. Rather, this dialog box simply presents a list of common assemblies that Visual

Studio 2008 is preprogrammed to display. When you are building applications that require the use

of an assembly not listed within the Add Reference dialog box, you need to click the Browse tab to

manually navigate to the *.dll or *.exe in question.
