4. What’s .NET?
• .NET Framework :
– A collection of technologies that …
• Unite isolated applications
• Make information available anytime, anywhere
• Simplify development and deployment

5. What’s .NET?
• .NET Framework :
– Common Language Runtime* – provides an abstraction layer over the
operating system
– Base Class Libraries
• pre-built code for common low-level programming tasks
– Development frameworks and technologies
• Reusable
• customizable solutions for larger programming tasks
_________________________________________________
*The Common Language Runtime (CLR) is the virtual machine component of the .NET Framework. All
.NET programs execute under the supervision of the CLR, guaranteeing certain properties and behaviors in
the areas of memory management, security, and exception handling.
