1 Creating Projects using Microsoft Visual Studio 2017 CTEC1239/2018S Computer Programming Version 1.0: Covers Windows 10 PCs in L2 Last updated:

2 Starting Visual Studio 2017 From the Windows 10 Taskbar

3 Starting Visual Studio 2017 Or, from the Windows 10 Start Menu

4 The splash screen is shown while Visual Studio loads it may take several seconds.

5 Visual Studio 2017 Note: in L2, the Dark colour theme is the default. It can be changed

6 Customizing Visual Studio From the Tools menu, select Options (right at the bottom). You can then change the Color theme, and make the font larger

7 Customizing Visual Studio Change the Color theme to Light (or Blue) for better contrast

8 Customizing Visual Studio From Fonts and Colors, the default font is already Consolas. You can make it larger for more detail on screen.

9 Create A New Project From the File menu, select New, then Project You can also press Ctrl+Shift+N instead 1 2 3

10 The New Project dialog box appears For every program we do in this course, under Visual C#, choose Windows Classic Desktop, then Console App (.NET Framework)

11 Choose the Project Location Click on Browse to pop up the Project Location dialog box. From here, choose or create a folder in which to store your projects. Each project will have its own subfolder. Choose your USB drive (recommended)! Because of the DeepFreeze software installed on the lab computers, you may lose your files on drive C.

12 Give the Project a Name The name will be used for both the project subfolder and the executable. For example, for the C# Console app above, the project folder will be C:\Users\Adminstrator\Desktop and the executable will be written to C:\Users\Adminstrator\Desktop\Hello\bin\Debug\Hello.exe Remove the checkmark from the Create directory for solution box Click OK when done.

13 New Project Created Type in code here Visual Studio creates an empty program framework. Add your own code in between the braces of the Main method.

14 Hello, Cruel World

15 C# Console App Code (2) The C# using keyword includes.net libraries. The C# namespace keyword is used because.net classes are organized in assemblies. Your project is an assembly.

16 C# Console App Code (3) Like Java, each C# program must have consist of at least one class. The program entry point is main, but C# capitalizes the name to Main (so does VB). The fully-qualified name of the class in this example is Hello.Program

17 C# Console App Files Don t mess with the Properties folder, App.config, Hello.sln or the Visual C# Project file! The bin and obj folders are used for building (they can be safely deleted).

18 C# Console App Files The Visual C# Project file has a.csproj extension The Visual Studio Solution file has a.sln extension

19 C# Console Executable The executable is built (linked) in the bin\debug folder; it has an.exe extension. You can run it directly from the command line. This file can also be copied to most other Windows computers by itself.

20 Contrived C# Console Program Example - Code

21 Hello, Cruel World Create a new project called Hello Enter one line of code:

22 Hello, Cruel World When you build and run the project by clicking on the green Start arrow -- the resulting console window simply opens and closes The program completes too quickly for the user to see the output! One more line of code is needed:

23 Hello, Cruel World Complete

24 Hello, Cruel World Complete

25 Cleaning C# Projects Close the project in Visual Studio. Copy the.exe file from bin\debug if necessary. Remove the bin and obj folders. Delete the secret hidden.suo file (VS2013 and older) or the secret hidden.vs folder (VS2015 and newer.) First, in Windows Explorer, click Organize, then Folder and Search Options, then from the View tab, click on Show hidden files, folders, and drives.

26 Archiving the Project If 7-Zip is installed, you can simply right-click on the project folder in Windows Explorer and create an archive (.7z or.zip) file. (This example was done under Windows 10 in L2.) The project folder and resulting 7-Zip archive file (both on Desktop)

27 Archiving the Project - Summary Close Solution (from the File menu) or exit Visual Studio. Follow the cleaning procedure. Using Windows Explorer, go to the folder where your project folder is Right click on the project folder and select 7-Zip and then Add to.7z (where is the name of your project/project folder) A.7z archive file will be created, which you can either copy to your USB or Network drive, safely , or post on BB.
