This flow shows the steps to install the .NET SDK, verify it, and run a simple program.

Execution Sample

C Sharp (C#)

dotnet --version
mkdir HelloWorld
cd HelloWorld
dotnet new console
dotnet run

These commands check the SDK version, create a new console app, and run it.

Execution Table

Step	Command	Action	Output/Result
1	dotnet --version	Check if .NET SDK is installed	Shows installed SDK version, e.g., 7.0.100
2	mkdir HelloWorld	Create a new folder for the project	Folder 'HelloWorld' created
3	cd HelloWorld	Change directory to the new folder	Current directory is now 'HelloWorld'
4	dotnet new console	Create a new console app project	Project files created with Program.cs
5	dotnet run	Build and run the console app	Outputs: 'Hello, World!'
6	Exit	Process complete	Setup and run successful

💡 All steps completed successfully, .NET SDK installed and app runs.

Variable Tracker

Variable	Start	After Step 1	After Step 4	After Step 5	Final
SDK Version	None	7.0.100	7.0.100	7.0.100	7.0.100
Current Directory	User Home	User Home	HelloWorld	HelloWorld	HelloWorld
Project Files	None	None	Program.cs and others	Program.cs and others	Program.cs and others
Program Output	None	None	None	Hello, World!	Hello, World!

Key Moments - 3 Insights

What if 'dotnet --version' shows an error?

It means the .NET SDK is not installed or not added to PATH. See step 1 in execution_table where a version number is expected.

Why do we create a new folder before 'dotnet new console'?

To keep projects organized. Step 2 creates the folder, step 3 moves into it, so the project files go inside this folder.

What does 'dotnet run' do exactly?

It builds and runs the program. Step 5 shows it outputs 'Hello, World!' confirming the app works.

Visual Quiz - 3 Questions

Look at the execution_table, what output do you get after running 'dotnet --version'?

A 7.0.100

B Hello, World!

C Folder created

D Error message

💡 Hint

Check Step 1 in the execution_table for the output of 'dotnet --version'.

At which step does the project folder 'HelloWorld' get created?

A Step 1

B Step 4

C Step 2

D Step 5

💡 Hint

Look at the 'Action' column in execution_table for folder creation.

If 'dotnet run' fails, which step should you check first?

A Step 1 - SDK version check

B Step 4 - Project creation

C Step 2 - Folder creation

D Step 3 - Change directory

💡 Hint

Step 4 creates the project files needed to run the app.

Concept Snapshot

.NET SDK Installation and Setup:
1. Download and run the .NET SDK installer.
2. Verify installation with 'dotnet --version'.
3. Create a project folder and navigate into it.
4. Use 'dotnet new console' to create a console app.
5. Run the app with 'dotnet run' to see output.
Ensure PATH is set for 'dotnet' command to work.

Full Transcript

To install and set up the .NET SDK, first download the installer from the official site and run it. After installation, open a terminal and type 'dotnet --version' to check if the SDK is installed correctly. Then create a new folder for your project and navigate into it. Use 'dotnet new console' to create a new console application. Finally, run 'dotnet run' to build and execute the program, which should print 'Hello, World!'. If any step fails, check the previous steps carefully, especially the SDK installation and project creation.
