Intoduction to c# and basics of .net
- 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 *[email protected] (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
