Overview - ASP.NET Folders

• ASP.NET 2.0 uses a file-based approach.

• we can add files and folders using the Add

Items option.

• Can add as many files and folders as we like.

• Dynamically compile them when required.

i.e, uses a predefined folder structure

containing the files, to compile them

dynamically.

Advantages of ASP.NET Application Folders

• Maintain resources in an organized manner.

• All files and folders are accessible through the

application.

• We can add as many files as required

• Files are compiled dynamically when required

Different Types of Application Folder

• App_Code Folders

• Bin Folders

• App_Data Folders

• App_Theme Folders

• App_Browser Folders

• App_WebReference Folders

• Resources Folders

– App_LocalResource Folders

– App_GlobalResource Folders

App_Code Folder

• App_Code Folder stores classes, typed data

sets, etc.

• All items stored in App_Code are

automatically accessible throughout the

application.

• If we store any class files (like .cs or .vb) it

compiles them automatically.

• We can add an App_Code folder, by

Solution File → right click → Add ASP.NET

Folder → App_Code.

• ASP.NET allows you to add

an App_Code folder only once.

• Can add new items like classes, text and xml

files into the App_Code folder.

• Items entered in App_Code folder is accessible

throughout the application.

• If we store different classes like .cs or .vb in

the same folder.

it will give following compilation error:

• We have to create separate folders for C# and

for VB or other classes.

Bin Folder• Contains compiled assemblies (.dll files) for

controls, components, or other code

• Can access those as a reference from anywhere of our web application.

• ASP.NET recognizes the presence of DLLs inside the Bin Folder.

• Main limitation-scope is limited to the current application.

• They cannot access any code outside of current web application.

App_Data Folder• Used as a data storage for the web application.

• Can store files such as .mdf(master database file-sql

server), .mdb(MS Access db format), and XML.

• Manages all of your application's data.

• Any file you place in it won't be downloadable.

App_Theme Folder

• To give your web sites a consistent look.

• When we add an App_Theme folder, a

subfolder with name Theme1 will be

automatically created.

• An App_Theme folder can contain two

subfolders;

– one for CSS files. - Cascading style sheets

– other for skin files. – property setting for controls

like BackColor,ForColor

App_Browser Folder

• App_Browser folder contains browser

information files (.browser files).

• used to identify the browser and browser

capabilities.

App_WebReference Folder

• Contain references to any web services.

• If we added any web services with our web

applications it go automatically into

App_Webreference

• In windows application, if we add DLL file it

would go under App_Webreference.

Resources Folders

• The main purpose of resource files

is localization of the web application.

• Supports multilingual functionality.(different

language supportive for a multinational

company website).

• There are two type of resources:

– Local resources

– Global resources

App_LocalResource Folder

• Multilingual functionality on webpage.

• Contains resources (.resx and .resources files)

that are associated with a specific page, user

control, or master page in an application.

App_GlobalResource Folder

• can be read from any page or code that is

anywhere in the web site.

• We should use theApp_GlobalResource folder

when we need a single resource for multiple

web pages.

web.config

• ASP.NET Web.config allows you to define or revise the configuration settings.

• Web.config files are stored in XML format which loads first.

• Connection string to database , Security , compilation setting would write here.

• All the Web.config files inherit the root Web.config file available at the following location.

i.e, systemroot\Microsoft.NET\Framework\versionNumber\CONFIG\Web.config location

• IIS is configured in such a way that it prevents

the Web.config file access from the browser.

• The changes in Web.config don’t require the

reboot of the web server.

Hierarchy of the Web.config file.

Thank you...

connectionStrings

• allows you to store multiple connection strings that are used in the application.
