Question

Suppose you are developing three versions — desktop, web, and mobile — of the BMI Calculator app. The Visual Studio solution folders containing the development files for these versions of the app are named bmiD_soln, bmiW_soln, and bmiM_soln, respectively. Correspondingly, the project folders for the the three versions are named bmiD_proj, bmiW_proj, and bmiM_proj, respectively. For the desktop version, the name specified for the UI is BMIForm, while the UI for the web app version is specified in the file bmiForm.aspx, and that for the mobile app is specified in the file bmiForm.xaml. The main project folder for each version of this application would then contain which files with the .cs extension; i.e., what are the names of these C# source code files?

Answer 1

Ans: Here according to question, 3 types of applications are created:

1.Desktop : That will run on windows so it is Windows application

2.Web : That will be web application ie website which will run over web

3. Mobile : This application will run over mobile and is popularly known as an app

These three types of web applications have been made up of BMI Calculator.Following are the names of solution folder name(given in question), project name (given in question),UI files name (given in question)and relevant source code files :

BMI Calculator

Application	Solution Folder Name	Project Folder Name	User Interface files	Source Code file(.cs files)
Dekstop	bmiD_soln	bmiD_proj	BmiForm	BmiForm.cs, BmiProgram.cs
Web	bmiW_soln	bmiW_proj	bmiForm.aspx	bmiForm.aspx.cs, bmiForm.aspx.designer.cs
Mobile	bmiM_soln	bmiM_proj	bmiForm.aspx	bmiForm.cs, bmiProgram.cs

Explanation : In Microsoft Visual C#.NET , .cs file is used to store "Code behind" the UI(User Interface ) files and program code.These files are known as source files.

In Desktop or windows application, Two source code files BmiForm.cs and BmiProgram.cs are created in which BmiForm.cs contain code behind the button(code to create a button),labels(code to create a label) etc and program.cs contain event driven codes related to controls that we use in the project (ex button_click,mouse_click ).

In Web application, Two source code files bmiForm.aspx.cs, bmiForm.aspx.designer.cs are created in which bmiForm.aspx.designer.cs contain code behind web controls like button(code to create a button),labels(code to create a label),textboxs(code to create a textbox).bmiForm.aspx.cs contain code event driven code and other logical code required to run a program)

In mobile application, two source code files bmiForm.cs, bmiProgram.cs are created . bmiForm.cs contain the code behind the controls used in form for example to create a listbox or button or textbox. bmiProgram.cs contain the event driven code i.e button_click,mouse_click and other logical code required in the project.
