Implementation Strategies

[This topic is pre-release documentation and is subject to change in future releases. Blank topics are included as placeholders.]

Visual Studio supports a rich object model that you can extend with automation add-ins, macros, VSPackages, or a combination of the three. Generally, add-ins and macros are easier to develop, but are less powerful, than VSPackages. Add-ins can call Visual Studio extensibility interfaces, and Visual Studio packages (VSPackages) can access the Visual Studio automation model. You can combine these two different approaches to create an effective solution.

VSPackages can be written in unmanaged or managed code. We recommend that you write new VSPackages in managed code by using the managed package framework (MPF). Almost anything that can be written in unmanaged code can be implemented more easily and securely in managed code. However, developers can expect legacy applications written in unmanaged code to continue to run in Visual Studio 2005.

The topics in the Visual Studio SDK documentation are presented in increasing order of power and complexity. Simple VSPackages can be implemented as tool windows or can send information to Visual Studio's built-in UI elements, such as the status bar or output window. More complex applications can be written as Visual Studio hierarchies, such as the Visual Studio Server Explorer. Still more power can be obtained by implementing a project, editor, or designer. Visual C# and Visual Basic are themselves implemented as Visual Studio language projects.
