3.NET Enterprise Servers Microsoft SQL Server™ 2000 Microsoft BizTalk™ Server 2000 Microsoft Host Integration Server 2000 Microsoft Exchange 2000 Enterprise Server Microsoft Application Center 2000 Microsoft Internet Security and Acceleration Server 2000 Microsoft Commerce Server 2000

4 The.NET Framework Components Win32 MessageQueuingCOM+ (Transactions, Partitions, Object Pooling) IISWMI Common Language Runtime.NET Framework Class Library ADO.NET and XML User Interface XML Web Services Visual Basic C++C# ASP.NET PerlPython… Windows Forms

5 Intermediate Language (IL) SourceCodeMachineLanguage C:\...\Application1 Productlib.dll Metadata Application1.exe MSIL Metadata CompilerCLR

6 Common Language Runtime (CLR) Base Class Library Support Thread Support COM Marshaler Type Checker Exception Manager MSIL to Native CompilersCodeManagerGarbageCollection Security Engine Debug Engine Class Loader

7.NET Framework Class Library System.Globalization System.Diagnostics System.Configuration System.Collections System.IO System.Reflection System.Net System System.Threading System.Text System.SecuritySystem.Runtime.InteropServices System.WebSystem.Windows.Forms System.Data

8 Languages in the.NET Framework Visual Basic.NET New version of Visual Basic with substantial language innovations C# – designed for.NET New component-oriented language Managed Extensions to Visual C++ Provides more power and control J#.NET Takes full advantage of the.NET Framework Third-party languages

9 What Are the Visual Basic.NET Enhancements? Major language enhancements Enhanced object-oriented support Structured exception handling Full access to the.NET Framework New threading options Garbage collection Enhanced Web development Create Web Forms as easily as Windows Forms Create Web Services quickly

10 Microsoft Visual Studio.NET There is one IDE for all.NET projects Solutions can contain multiple programming languages Example: Visual Basic.NET and C# in the same solution The IDE is customizable through “My Profile” The IDE has a built-in Internet browser IDE = Integrated Development Environment

11 Project Template Windows Application Class Library Windows Control Library ASP.NET Web Application / Service / Control Library Console Application Windows Service Others

12 Project Structures Solution files (.sln,.suo) Project files (.vbproj) Local project items Classes, forms, modules, etc. (.vb) Web project items XML Web services (.asmx) Web forms (.aspx) Global application classes (.asax)

13 Assemblies An assembly is an.exe or.dll file with other supporting files that make up a Visual Studio.NET application Assemblies are created automatically when you compile source files Click Build on the Build menu Use the command-line command vbc.exe

14 Using Solution Explorer Displays project hierarchy Project references Forms, classes, modules Folders with subitems “Show All Files” mode Manipulating projects Drag-and-drop editing Context menus

15 Using Properties Window Displays object properties Display modes Alphabetic Categorize Special Properties "+" on the left bar Dynamic Properties

16 Using ToolBox  Display tools for develop application.  Controls are grouped in tabs.  Using Drag and Drop to parse any controls to application.

17 Using Server Explorer Managing Data Connections Viewing and Managing Servers Using Drag-and-Drop Techniques

18 Using the Object Browser Examine objects and their members Access lower-level items Shows inheritance and interfaces Examine how the.NET Framework class libraries use Inheritance Class Namespace Method Library Inheritance

19 Using the Task List Similar to the Tasks feature in Microsoft Outlook Stored with the solution in the.suo file Adding to the Task List You can add tasks manually by typing in appropriate field Visual Basic.NET adds build errors, upgrade comments, etc. You can use token strings to add comments in code

20 Using Dynamic Help Automatically displays relevant Help topics based on focus and cursor placement Use the Options dialog box to configure the Dynamic Help window
