ASP .NET folders and
web.config

6. Overview - ASP.NET Folders
• ASP.NET 2.0 uses a file-based approach.
• we can add files and folders using the Add
Items option.

7. • 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.

8. 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

9. 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

10. 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.

11. • We can add an App_Code folder, by
Solution File → right click → Add ASP.NET
Folder → App_Code.

12. • 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.

13. • 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:

14. • We have to create separate folders for C# and
for VB or other classes.

15. 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.
• Keeping .pdb files inside Bin folder helps us in
debugging.
• Main limitation-scope is limited to the current
application.
• They cannot access any code outside of current web
application.

17. App_Data Folder
• Used as a data storage for the web application.
• Can store files such as .mdf, .mdb, and XML.
• Manages all of your application's data.
• Any file you place in it won't be downloadable.

18. 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.
– other for skin files.

20. • We could select the theme from aspx page.

21. App_Browser Folder
• App_Browser folder contains browser
information files (.browser files).
• used to identify the browser and browser
capabilities.

22. App_WebReference Folder
• Contain references to any web services.
• Contains reference contract files (.wsdl files),
schemas (.xsd files), and discovery document
files (.disco and .discomap files) that let you
create a Web reference

23. Resources Folders
• The main purpose of resource files
is localization of the web application.
• There are two type of resources:
– Local resources
– Global resources

24. App_LocalResource Folder
• Contains resources (.resx and .resources files)
that are associated with a specific page, user
control, or master page in an application.

25. 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.

26. web.config
• ASP.NET Web.config allows you to define or revise
the configuration settings.
• Web.config files are stored in XML format.
• Can have any number of Web.config files for an
application.
• All the Web.config files inherit the
root Web.config file available at the following
location.
i.e,
systemrootMicrosoft.NETFrameworkversionNu
mberCONFIGWeb.config location

27. • 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.

28. Hierarchy of the Web.config file.

29. system.web
•Compilation Settings
•Page Settings

30. Custom Error Settings
Example error status code:
•400 Bad Request
