  1. Web Server Programming Visual Studio Creating a Simple ASP.NET Application

  2. Content • The .NET Framework • Visual Studio 2012 Environment • A Simple ASP.NET Web Application Muzaffer DOĞAN - Anadolu University

  3. The .NET Framework Muzaffer DOĞAN - Anadolu University

  4. The .NET Framework • .NET Framework is a cluster of several technologies: • .NET Languages: C#, Visual Basic.NET, JScript.NET, J#, C++ • The Common Language Runtime (CLR): The engine that executes all .NET programs • The .NET Framework Class Library: The class library for many prebuilt functionality (e.g. ADO.NET, Windows Forms, etc.) • ASP.NET • Visual Studio.NET Muzaffer DOĞAN - Anadolu University

  5. .NET Languages • C# is designed for .NET technology • C# and VB.NET uses the same .NET library • C# and VB.NET codes are very similar • VB6.0 and VB.NET are different languages because VB.NET is an object-oriented language • A C# programmer can easily understand and convert VB.NET programs Muzaffer DOĞAN - Anadolu University

  6. Intermediate Language (IL) • All .NET languages are compiled into another low-level language before the code is executed • This lower-level language is the Common Intermediate Language (CIL, or just IL) • Because of this feature, C# programs can use VB.NET (or any other .NET language) components • Every EXE or DLL file built with a .NET language contains IL code • .NET Framework should be installed on the computer that the .NET program is deployed Muzaffer DOĞAN - Anadolu University

  7. Compilation Muzaffer DOĞAN - Anadolu University

  8. Execution Muzaffer DOĞAN - Anadolu University

  9. .NET Class Library Muzaffer DOĞAN - Anadolu University

  10. Common Language Runtime (CLR) Muzaffer DOĞAN - Anadolu University

  11. History of .NET Muzaffer DOĞAN - Anadolu University

  12. .NET Framework Versions Muzaffer DOĞAN - Anadolu University

  13. What’s New in the .NET Framework Muzaffer DOĞAN - Anadolu University

  14. Muzaffer DOĞAN - Anadolu University

  15. ASP.NET Versions • ASP.NET 1.0: First release • ASP.NET 1.1: Added performance, bug-fixes but no new features • ASP.NET 2.0: Prebuilt goodies that developers can use without writing much code. New features: Website navigation, easier database access, theming for web page design • ASP.NET 3.5: Embedded Ajax, LINQ Muzaffer DOĞAN - Anadolu University

  16. Now, in this course? • In this course, we’ll be developing • ASP.NET 4.5 applications • over .NET Framework 4.5 • on Visual Studio 2012 • using C# 5.0. Muzaffer DOĞAN - Anadolu University

  17. Visual Studio 2012 Muzaffer DOĞAN - Anadolu University

  18. Visual Studio Features • Page Design: Drag & drop style; you don’t need to understand HTML • Automatic Error Detection • Debugging Tools • Intellisense: Statement completion for recognized objects and listing information automatically Muzaffer DOĞAN - Anadolu University

  19. 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.

  20. 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

  21. 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

  22. Toolbox Designer Solution Explorer Properties Window

  23. Source Code Solution Project Source Files
