.NET SDK Installation and Setup in C Sharp (C#) - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to print the .NET runtime version installed on your machine.

C Sharp (C#)

Console.WriteLine(".NET Runtime Version: " + [1]);

Drag options to blanks, or click blank then click option'

AEnvironment.GetEnvironmentVariable("DOTNET_VERSION")

BSystem.Environment.Version.ToString()

Cdotnet --version

DConsole.ReadLine()

💡 Hint

Common Mistakes

Trying to run shell commands like 'dotnet --version' directly in code.

Using Console.ReadLine() which waits for user input instead of showing version.

The System.Environment.Version.ToString() method returns the version of the .NET runtime.

2fill in blank

medium

Complete the code to create a new console project using the .NET CLI command.

C Sharp (C#)

var process = new System.Diagnostics.Process();
process.StartInfo.FileName = "dotnet";
process.StartInfo.Arguments = "[1]";
process.Start();

Drag options to blanks, or click blank then click option'

Abuild console

Bcreate console

Cinit console

Dnew console

💡 Hint

Common Mistakes

Using 'create' or 'init' which are not valid dotnet commands.

Using 'build' which compiles but does not create a project.

The correct .NET CLI command to create a new console project is dotnet new console.

3fill in blank

hard

Fix the error in the code that tries to check if the .NET SDK is installed by running 'dotnet --version'.

C Sharp (C#)

var process = new System.Diagnostics.Process();
process.StartInfo.FileName = "dotnet";
process.StartInfo.Arguments = "[1]";
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.UseShellExecute = false;
process.Start();

Drag options to blanks, or click blank then click option'

A--version

Bshow-version

Cversion

D-version

💡 Hint

Common Mistakes

Using '-version' or 'version' without double dashes.

Setting UseShellExecute to true which prevents output redirection.

The correct argument to get the .NET SDK version is --version.

4fill in blank

hard

Fill both blanks to install the latest .NET SDK using the command line.

C Sharp (C#)

string command = "dotnet [1] [2]";

Drag options to blanks, or click blank then click option'

Ainstall

Bupdate

Cnew

Dupgrade

💡 Hint

Common Mistakes

Using 'new' which creates projects, not installs SDK.

Using 'upgrade' which is not a dotnet CLI command.

The command dotnet install update is not a valid .NET CLI command. The correct way to install or update the SDK is outside the dotnet CLI, but for this exercise, the blanks expect install and update as placeholders.

5fill in blank

hard

Fill all three blanks to check the installed SDK version and print it in C#.

C Sharp (C#)

var process = new System.Diagnostics.Process();
process.StartInfo.FileName = "dotnet";
process.StartInfo.Arguments = "[1]";
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.UseShellExecute = [2];
process.Start();
string output = process.StandardOutput.ReadToEnd();
process.WaitForExit();
Console.WriteLine("Installed SDK version: " + [3]);

Drag options to blanks, or click blank then click option'

A--version

Bfalse

Coutput

Dtrue

Attempts:

3 left

💡 Hint

Common Mistakes

Setting UseShellExecute to true which disables output redirection.

Using wrong argument like '-version' or 'version'.

Printing the wrong variable instead of the output.

To get the SDK version, run dotnet --version. Redirecting output requires UseShellExecute = false. The output is read into the variable output and printed.
