ASP.NET Mobile Development with Visual Studio 2008

Download Template

1.Download Template First

2.Copy zip files with filenames ending with "_cs" to:

[My Documents]\Visual Studio 2008\Templates\ItemTemplates\Visual C#

3.open your visual studio 2008 website project again

4.Right Click Solution Explore and select Add new Item....

5.In the Add New Item dialog box ,in My Template Selection select Mobile Form(select language C#)

To help users with this scenario, I've created the following item templates for ASP.NET Web Site and ASP.NET Web Application projects:

Mobile Web Form
Mobile Web User Control
Mobile Web Configuration File

The templates are available in both VB and C# versions.

One limitation users should be aware of is the Design View in Visual Studio 2008, which is based on a completely new archtecure, does not display ASP.NET mobile controls. However, using these templates you should be able to develop ASP.NET Mobile applicaitons using the Source View just fine.

Once installed, these templates enable users to create and edit new ASP.NET Mobile Web Forms in ASP.NET Web Site and ASP.NET Web Applicaiton project types.

To install these templates download the attachment included in this post, extract the ZIP file, and follow the instructions in the included readme.txt files.

What is IIS?

2012-05-09T00:43:00.002-07:00

Internet Information Services (IIS) – formerly called Internet Information Server – is a web server application and set of feature extension modules created by Microsoft for use with Microsoft Windows

History

The first Microsoft web server was a research project at European Microsoft Windows NT Academic Centre (EMWAC), part of the University of Edinburghin Scotland, and was distributed as freeware. However, since the EMWAC server was unable to scale to handle the volume of traffic going toMicrosoft.com, Microsoft was forced to develop its own web server, IIS.
