Grading Plan 1 st MT: 20%, 2 nd 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%. 7

Sample Grading Plan Grade Letter Grade ≥ 80AA ≥ 75AB ≥ 70BA ≥ 65BB ≥ 60BC Grade Letter Grade ≥ 55CB ≥ 50CC ≥ 45CD ≥ 40DC ≥ 35DD < 35FF 8

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 page You can login to the website using your Anadolu account. If you have problems in logging in, please inform me. 10

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. 12

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 edition 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 49
