Grading Plan

• 1st MT: 20%, 2nd MT: 20%, Homework: 20%,Final: 40%.

• Curve will be applied to the grades• If your grade is below 80%, you cannot get the

grade AA, but it is not certain that if you pass 80% then you get AA.

• If your grade is below 35%, you certainly fail, but this does not mean that you’ll get at least DD if you pass 35%.

Attendances

• You don’t have to attend the classes but recent experiences show that the students who attend the classes are more successful

• All students are responsible for visiting the website of the course at least two times in each week

• Announcements, assignments, grades, and project subjects will be published on the website.

9

Supplementary Software

• In this course, you’ll need Visual Studio 2012 software

• You can download it from a shared folder as explained in http://ceng.anadolu.edu.tr/msdn.aspx page

• You can login to the website using your Anadolu e-mail account.

• If you have problems in logging in, please inform me.

Setting the Visual C# Settings

11

Visual C# Keyboard Settings• After installing Visual Studio 2012, select the Visual C#

Settings from the Default Collection of Settings window.• This sets the keyboard commands and the user interface

for the C# environment.– Run: Ctrl-F5, Debug: F5, Build: Ctrl-Shift-B, etc.– New Website command in the Start Page if you select Web

Development settings.• If you miss the window, or select another setting, then

select the command Import and Export Settings from the Tools menu.

Conclusion

• You can use C# to create several types of applications

• Creating a Windows Forms Application and an ASP.NET Application are similar

• You can also create mobile applications in C# (for only Windows Mobile devices)

• You can use a powerful IDE, Visual Studio 2012, to develop applications (Express editon of Visual Studio is free of charge)

41

.NET Framework

• Microsoft’s platform to develop applications• It may run on several operating systems– Mono on Linux and Mac OS– .NET Compact Framework on PDAs and smartphones

• It supports several types of applications– Windows applications, web applications, web

services, mobile applications, etc.• It supports several programming languages– C#, C++, Visual Basic, Jscript, COBOL, Java, Delphi, etc.

42

What’s in the .NET Framework

• Library of codes that you use from your client language (C#, VB, etc.) using OOP techniques

• .NET Common Language Runtime (CLR) executes .NET applications (similar to JRE)

• The codes are compiled into Common Intermediate Language (CIL) codes (like .class files in Java)– CIL codes are independent of the OS

• Just-in-time (JIT) compiler compiles the CIL codes to native code of the OS– JIT compiler compiles the CIL codes only when it is needed

43

Managed Code

• Code written using the .NET Framework is managed

• It means that the CLR looks after your applications by managing memory, handling security, etc.

• In C#, you can write only managed codes• In C++, you can write both managed and

unmanaged codes

44

Garbage Collection

• In unmanaged codes, the programmer have to manage the memory so that all allocated memory spaces are freed at the end of the program

• But in managed codes, memory allocation and deallocation are managed by the CLR. This concept is called garbage collection

• .NET garbage collection works periodically and deallocates memory spaces that are no longer needed

45

C#

• An evolution of the C and C++ languages• Created by Microsoft specifically to work with

the .NET platform• Designed to incorporate many of the best

features from other languages, while clearing up their problems

46

Visual Studio 2012• A powerful integrated development environment (IDE)• Automates the steps required to compile source code• Intelligently detect errors and suggest code where

appropriate as you are typing (Intellisense)• Includes designers, enabling simple drag&drop design of

UI elements• Includes starter projects• Enables deployment• Enables debugging• etc.

47

Visual Studio Versions

• Visual Studio Professional• Visual Studio Premium• Visual Studio Ultimate• Visual Studio Express Edition: Free, but some

features are absent• Visual C# Express: Contains only C#• Visual Web Developer Express: Contains only

web application tools

48

Visual Studio Solutions

• You create solutions in Visual Studio• Solutions contain projects• Solutions can contain multiple projects– This enables you to work on shared code
