.NET is both a business strategy from Microsoft and its collection of programming support for what are known as Web services, the ability to use the Web rather than your own computer for various services. http://www.thinkittraining.in/dotnet

2. *Introduce C# language
*ECMA standard
*originally developed by MSR
*not just Java + C++
*many extensions
*Introduce .NET framework
*future of Windows
*base of Microsoft’s C# implementation

3. *Teach you to program
*should be very comfortable writing OO code
*we will not cover much if any basic programming
*Introduce object oriented languages
*not even teach you OO style (except wrt C#)
*expected to write all code in OO style
*Give you a detailed grade
*S/U only
*even homework

4. *Requirements for the course
*come to lecture
*participate
*do three assignments
*Assignments are S/U
*will not be giving a detailed grade
*show me that you understand the concepts, and can
write C# code
*All three assignments will be online soon
*must be completed by the end of the course

5. *Class time MWF 12:20-1:10
*office hours: W 10:30-12 or by appointment
*tmroeder@cs.cornell.edu (4112 Upson)
*Prerequisites: CS 211/212
*really: experience in OO coding/concepts
*Academic Integrity
*Do not submit work that is not your own
*minimum penalty: U in the course

6. *Visual C#
*Express: Google “Visual C# Express”
*in Visual Studio: MSDNAA
*must be version 2005: we need C# 2.0
*Mono: http://www.go-mono.com
*Open Source impl for Linux: not quite at 2.0
*Rotor: http://msdn.microsoft.com/net/sscli
*Shared Source impl for Windows (through 2.0)
*Used to work on BSD / OS X, too

7. *Portable.NET: http://www.dotgnu.org
*yet another open source impl
*CMS: http://cms.csuglab.cornell.edu
*we will use this for homework
*turn on your email notifications!
*Course Webpage:
http://www.cs.cornell.edu/courses/cs215
*will post lectures online
*as well as any errata for the homework

8. *You all will have accounts
*MSDNAA access: let me know if you don’t
currently have it
*http://www.csuglab.cornell.edu/userinfo.html
*Visual Studio .NET 2005 should be installed there

9. *You all will have accounts
*MSDNAA access: let me know if you don’t
currently have it
*http://www.csuglab.cornell.edu/userinfo.html
*Visual Studio .NET 2005 should be installed there

10. *Syllabus (10 more lectures)
*C# constructs: 5 lectures
*Types, Delegates, Generics,
Reflection, Iterators
*.NET Memory Management: 1 lecture
*Topics: 4 lectures
*C# 3.0, Threading, Security, MSIL,
MSH

11. *Each class will begin with a quiz
*not for credit but for knowledge
*but I will collect them and see what you know
*Today’s quiz will be on prerequisites
*OO programming, mainly to do with Java
*If you don’t know Java, but do have OO
experience, it’s OK
*talk to me after if you have trouble

12. *A Framework in which to run code
*A Common Language Runtime (CLR)
*runs all programs
*C# compiles to Microsoft Intermediate Language
*MSIL runs on CLR
*Virtual Machine like Java
*code written in many languages compiles to MSIL
*A Common Language Specification (CLS)
*A Common Type System (CTS)

13. Runtime
Operating System
.NET Framework
Common
Type
System
Common
Language
Runtime
Building Blocks (e.g. for Services)
Services: .NET and COM+
SQL Server BizTalk ...
Languages:
C#, Visual Basic, etc
.NET Applications
Enterprise Servers
...Sharepoint ...
Web Services

14. Class Loader
MSIL to Native
Compilers (JIT)
Code
Manager
Garbage
Collector (GC)
Security Engine Debug Engine
Type Checker Exception Manager
Thread Support COM Marshaler
Base Class Library Support

15. *A set of common types
*any language that runs in CLR should implement
*no syntax specified
*Languages often define aliases
*For example
*CTS defines System.Int32 – 4 byte integer
*C# defines int as an alias of System.Int32
