Keep your technology and business options open, while building a practical yet scalable application that matches your current needs now and in the future. The pre-built templates and components in LightSwitch are fully extensible, so you can get the specific functionality your application demands. In addition, your application can grow to meet the increasing demands of popular applications using the Microsoft Windows Azure Cloud Hosting option.

Visual Studio 2008 When you create web pages in Visual Studio 2008, they are by default XHTML 1.0 Transitional. Sometimes developer want more control over the DocType or they want their pages to be XHTML 1.0 compliance. So you can also change the DocType or if you are using master pages then changing DocType is very easy just change the DocType in master page and all the child pages that use the master page will automatically acquire the DocType.

  • First you need to modify the visual studio template file. You can find the visual studio template file path “C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\ItemTemplates\Web\VisualBasic\1033\”.
  • Unzip the and modify these two file “WebForm.aspx and WebForm_cb.aspx”.
  • Simply change the DocType.
  • After updating the visual studio template files, delete the                            c:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\ItemTemplatesCache folder to clear out the template cache.
  • Run Visual Studio using the following command line to rebuild the template cache:
