Locating application files on the SharePoint server

Deployment of a SharePoint application affects files in several locations on the server.

File locations

The SharePoint hosting web application is located in the VirtualDirectories folder, e.g.:

C:\Inetpub\wwwroot\wss\VirtualDirectories\34318

Location	Contents
~\bin	all application dlls: MyApp.dll, MyApp.Business.dll, MyApp.Data.dll, AjaxControlToolkit.dll, MyAppBaseClasses.dll, CarlosAg.ExcelXmlWriter.dll, Ciloci.Flee.dll, FredCK.FCKeditorV2.dll, MySql.Data.dll, Report.dll
~\App_Themes	Iron Speed Designer creates a subfolder for each theme name, e.g., MyAppInherited, containing the BaseStyles.css and Styles.css style sheet files.
~\App_GlobalResources	Resource files such as MyApp.resx, MyAppBaseClasses.resx, MyApp.en-US.resx, MyAppBaseClasses.en-US.resx, etc.

SharePoint site content

The full application is copied into the Layouts folder, e.g.:

SharePoint 2010:

C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS\MyApp3

SharePoint 2007:

C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\TEMPLATE\LAYOUTS\MyApp3

SharePoint permissions configuration files

The SharePoint trust (permissions) configuration files are located in the “config” subfolder of the “12” or “14” hive, e.g.:

SharePoint 2010:

C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\config\wss_mediumtrust.config

SharePoint 2007:

C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\config\wss_mediumtrust.config

Modifications made to the Hosting application’s Web.config file

Iron Speed Designer modifies your application’s ~\web.config file to:

Add SafeControls to hosting Web Application Apps web Config for every DLL, such as
<SafeControl Assembly="MyAppBaseClasses" Namespace="BaseClasses" TypeName="*" Safe="True" />
Set trust to WSS_Medium in hosting web.config. The default is:
<trust level="WSS_Minimal" originUrl="" />)
Add Menu Provider to hosting web config, e.g.:
<add name="MyAppMenuElementsProvider" type="System.Web.XmlSiteMapProvider" siteMapFile="~/_layouts/MyApp/Menu Panels/menu.sitemap" />
Add Session and add ScriptModule tags to the <httpModules> section, e.g.:
<add name="Session" type="System.Web.SessionState.SessionStateModule"/>
<add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
Add verb to <httpHandlers> section after <remove verb…>, e.g.:
<add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" validate="false" />

Your application’s Web.config file is modified using the WebConfigModifications class of SharePoint so that all modifications are tracked and managed by SharePoint. Thus, a .bak backup file is being created (e.g., web_2010_02_10_14_09_33.bak).

Modifications made to the Medium trust configuration file

Iron Speed Designer modifies the FileIOPermission class to allow path discovery inside the deployed application.
