1) Short Note of coding model of ASP.NET.

ANS) ASP.NET coding models are the methodologies used for writing code in a web application.

ASP.NET provides two coding models: 

1. Inline Coding Model  

2. Code Behind Model

  

Inline coding :-

• Inline Coding model was introduced earlier to the code-behind model. 
• In this model, the code required to implement a web page is directly placed in the .aspx file on the application.
• The major drawback of this coding model is that, you need to write the code to implement various functionalities of a web application and the HTML code in a common file.           

           Code Behind Model :- 

• To deal with this drawback of Inline Code model, ASP.NET 1.0 introduced the code behind model. 
• In the Code Behind Model, you have to maintain a separate code file for each web page. It uses concept of Partial classes. 
• One file store the code to implement the functionalities of a web page, and the other file stores the HTML coding of a web application.
• Suppose that we have created a web page called “default” then in the Code-Behind Model HTML code will be stored in default.aspx file and C# Code will be stored in default.aspx.cs file.
• If the code written in vb language instead of C#, then this code will be stored in “default.aspx.vb” file.

2)  Built-in directories of ASP.NET 

ANS) 

Important built in directories are listed below :

• App_Data
• App_Code
• Bin
• App_Themes
• App_GlobalResources
• App_Browsers

App_Data

• This folder holds the data stores utilized by the application.
• It can store files such as .mdf, .mdb, and XML
• It manages all of your application's data centrally.
• Not only that, but it is accessible from anywhere in your web application
• The real advantage of the App_Data folder is that, any file you place there won't be downloadable
• We can add .mdf files to the App_Data folder directly by selecting Add New Item.
• From there we can a create table, procedure or function without opening SQL Server.

App_Code

• The App_Code Folder stores classes, typed data sets, etc.
• All the items that are stored in App_Code are automatically accessible throughout the application. 
• If we store any class files (like .cs or .vb) it compiles them automatically.

Bin

• The Bin folder is used for keeping assemblies inside it
• We can access those as a reference from anywhere of our web application
• Use of Bin folder comes into the picture if we use any class library within our web application. 

App_Themes 

• If you want to give your web sites a consistent / uniform look, then you need to design themes for your web application.
• The App_Themes folder contains all such themes.
• An App_Theme folder can contain two subfolders; one for CSS files and the other for skin files.

App_GlobalResources 

• The App_GlobalResource folder can be read from any page or code that is anywhere in the web site.
• Global resources must be stored in the App_GlobalResource folder at the root of the application.
• We should use the App_GlobalResource folder when we need a single resource for multiple web pages. We can define ASP.NET control properties by manually associating them with resources in global resource files. 

App_Browser

• The App_Browser folder contains browser information files (.browser files).
• These files are XML based files which are used to identify the browser and browser capabilities
