Corillian's product is a "Component Container." Name at least 3 component containers that ship now with the Windows Server Family.

Purpose:

• This is a bit of a weird question that does not serve much purpose in my personal opinion.
• At best it tests whether a developer has worked inside the component based areas of the framework like Windows Forms and Web Forms. 
• Perhaps tying ones answer back to the IDisposable pattern inherent in containers might illustrate a superior knowledge.

Potential Answers:

There are various component containers contained in the .Net Framework class library and since .Net comes pre-installed with Windows Server family one could reference any of the component based framework features (web forms or windows forms are the easiest):

• System.Web.UI.Page, 
• System.Windows.Forms.Form 
• System.ComponentModel.Container

At a high level, components are any version controlled reusable code elements and component container manages these either visually or not. 

For example the form (windows or web) is nothing more that visual component container of IComponnet based controls that are rendered and the life cycle of which is managed. Important to note that not all component containers are visual in nature.
