  6. Course Contents (continued)

  7. 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%.

  8. Sample Grading Plan

  9. 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.

  10. 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.

  11. Setting the Visual C# Settings

  12. 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.

  13. Creating a Console Application

  14. Write the code and press Ctrl-F5

  16. Drag & drop a label and button onto the form

  17. Double-click the button

  18. Write the code and press Ctrl-F5

  19. Click the button

  20. Creating an ASP.NET Web Page

  21. Do NOT select File -> New -> Project -> ASP.NET Web Forms Application

  22. Right-click the project name and select Add -> Add New Item (equivalently: Add -> Web Form)

  23. Switch to Design View

  24. Put a Label, press the Enter key, and put a Button

  25. Double-click the button

  26. Write the code and press Ctrl-F5

  27. Click the button

  28. 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)

  29. .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.

  30. 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

  31. 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

  32. 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

  33. 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

  34. 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.

  35. 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

  36. 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

  37. Toolbox Designer Solution Explorer Properties Window
