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

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

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

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

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
