<h2>Background</h2>
<p>Cell phones (mobile telephones) have become part of our life style.</p>
<p>One exciting thing about mobile devices is their ability to connect
to the Internet and to execute web applications.</p>
<p>Mobile applications can now be developed to deliver any types of data, to any
user, any place in the world!</p>
<p>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.</p>
<p>To support all types of mobile devices, developers must create one different application
for each language.</p>
<p>With .NET Mobile, Microsoft has introduced a new platform for developing mobile applications.</p>
<p>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. </p>
<hr />
<h2>What You Should Already Know</h2>
<p>Before you continue you should have a basic understanding of the following:</p>
<ul>
<li>HTML / XHTML</li>
<li>XML namespaces</li>
<li>ASP .NET</li>
</ul>
<p>If you want to study these subjects first, find the tutorials on our
<a href="../default.asp">Home page</a>.</p>
<hr />
<h2>.NET Mobile</h2>
<p>.NET Mobile is an extension to Microsoft ASP.NET and the Microsoft's .NET Framework.</p>
<p>.NET Mobile is a set of server-side Forms Controls to build applications for
wireless mobile devices.</p>
<p>These controls produce different output for different devices by
generating WML, HTML, or
compact HTML.</p>
<hr />
<h2>How Does It Work?</h2>
<p>The following table shows how the .NET Mobile works:</p>
<table border="1" width="100%" class="ex">
<tr>
<td align="center">Mobile Devices</td>
</tr>
<tr>
<td align="center">The Internet</td>
</tr>
<tr>
<td align="center">Internet Information Services - IIS</td>
</tr>
<tr>
<td align="center">The .NET Framework</td>
</tr>
<tr>
<td align="center">ASP.NET</td>
</tr>
<tr>
<td align="center">.NET Mobile</td>
</tr>
</table>
<ul>
<li>A web client requests a web page</li>
<li>The request travels the Internet</li>
<li>The request is received by IIS</li>
<li>The request is handled by the .NET framework</li>
<li>The requested page is compiled by ASP.NET</li>
<li>.NET Mobile handles any mobile device requirements</li>
<li>The page is returned to the client</li>
</ul>
<hr />
<h2>Software Requirements</h2>
<p>To develop mobile applications with .NET Mobile, you must have the following
components:</p>
<ol>
<li>Windows 2000 Professional/Server with IIS 5</li>
<li>All Windows 2000 service packs</li>
<li>The ASP.NET framework</li>
<li>Microsoft Mobile Internet Toolkit (MMIT)</li>
<li>Internet Explorer 5.5 or later</li>
<li>A WAP simulator</li>
</ol>
<p>You will need Windows 2000 to develop .NET applications (IIS 5 (Internet Information Services) is a part of Windows 2000). </p>
<p>If you want to read more about how to install .NET go to our
<a href="../aspnet/default.asp">ASP.NET tutorial</a>.</p>
<p>You also have to install MMIT (.NET Mobile).</p>
<p>Internet Explorer and MMIT can be downloaded from
<a target="_blank" href="../../msdn.microsoft.com/default.htm">Microsoft MSDN</a>.</p>
<hr />
<h2>How To Start</h2>
<p>Developing a mobile web application with ASP.NET is very easy:</p>
<ol>
<li>Create an ASP.NET page</li>
<li>Include System.Mobile.UI </li>
<li>Add Mobile Controls to the page</li>
</ol>
<p>See the details in the next chapters.</p>
