9
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



Classes, forms, modules, etc. (.vb)
Web project items

XML Web services (.asmx)

Web forms (.aspx)

Global application classes (.asax)
12
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
13

18
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
19
