Background

Cell phones (mobile phones) have become part of our life style.

Today,  mobile devices can connect to the Internet, and execute web applications.

Mobile applications can now be developed to deliver any types of data, to any user, any place in the world!

Different mobile devices support different programming languages. Some support WAP and WML, some support HTML or a limited version of HTML, and some support both or a different language.

To support all types of mobile devices, developers must create one different application for each language.

With .NET Mobile, Microsoft has introduced a new platform for developing mobile applications.

This tutorial is about how to develop applications with an extension to the .NET Framework, called the Microsoft Mobile Internet Toolkit (MMIT) or simply .NET Mobile.

The .NET Framework

ASP.NET

.NET Mobile

• A web client requests a web page
• The request travels the Internet
• The request is received by IIS
• The request is handled by the .NET framework
• The requested page is compiled by ASP.NET
• .NET Mobile handles any mobile device requirements
• The page is returned to the client

1. Windows 2000 Professional/Server with IIS 5
2. All Windows 2000 service packs
3. The ASP.NET framework
4. Microsoft Mobile Internet Toolkit (MMIT)
5. Internet Explorer 5.5 or later
6. A WAP simulator

You will need Windows 2000 to develop .NET applications (IIS 5 (Internet Information Services) is a part of Windows 2000).

If you want to read more about how to install .NET go to our ASP.NET tutorial.

You also have to install MMIT (.NET Mobile).

Internet Explorer and MMIT can be downloaded from Microsoft MSDN.
