2	Install PowerShell Extension			Extension adds PowerShell support
3	Open or create script file	Write-Host "Hello, PowerShell in VS Code!"		Script file ready for editing
4	Run script in terminal	Write-Host "Hello, PowerShell in VS Code!"	Hello, PowerShell in VS Code!	Output appears in integrated terminal
5	Modify script	Write-Host "Script updated"		Edit script to change output
6	Run updated script	Write-Host "Script updated"	Script updated	New output shown
7	Exit			Close VS Code or stop running scripts

💡 User closes VS Code or stops running scripts

Variable Tracker

Variable	Start	After Step 4	After Step 6	Final
Script Content	"Write-Host \"Hello, PowerShell in VS Code!\""	"Write-Host \"Hello, PowerShell in VS Code!\""	"Write-Host \"Script updated\""	"Write-Host \"Script updated\""
Terminal Output	""	"Hello, PowerShell in VS Code!"	"Script updated"	"Script updated"

Key Moments - 3 Insights

Why doesn't the script output appear in a popup window?

The output appears in the integrated terminal inside VS Code, as shown in execution_table step 4, because PowerShell scripts run in the terminal environment.

How do I know if the PowerShell extension is installed correctly?

When you open a .ps1 file, VS Code highlights syntax and offers IntelliSense. This is implied after step 2 in the execution_table.

Can I run scripts without saving the file?

No, you need to save the script file first to run it in VS Code terminal, as shown in step 3 before running in step 4.

Full Transcript

This lesson shows how to use Visual Studio Code with the PowerShell extension to write and run PowerShell scripts. First, open VS Code and install the PowerShell extension. Then open or create a PowerShell script file with the .ps1 extension. Write your script, for example, a simple Write-Host command to print a message. Run the script in the integrated terminal inside VS Code. The output appears there. You can edit the script and run it again to see updated output. When done, close VS Code or stop running scripts. This process helps beginners see how code changes affect output step-by-step in a friendly editor.
