Create a sample .NET project

To set up a .NET project to work with dependencies, we’ll use Visual Studio Code. Visual Studio Code includes an integrated terminal, which makes creating a new project easy. If you don’t want to use another code editor, you can run the commands in this module in a terminal.

1. In Visual Studio Code, select File > Open Folder.
2. Create a new folder named DotNetDependencies in the location of your choice, and then select Select Folder.
3. Open the integrated terminal from Visual Studio Code by selecting View > Terminal from the main menu.
4. In the terminal window, copy and paste the following command.
   .NET CLI

dotnet new console -f net6.0

This command creates a Program.cs file in your folder with a basic “Hello World” program already written, along with a C# project file named DotNetDependencies.csproj.

You should now have access to these files.

• -| obj
  -| DotNetDependencies.csproj
  -| Program.cs
  

• In the terminal window, copy and paste the following command to run the “Hello World” program.
  .NET CLI

dotnet run

Add a NuGet package by using the .NET Core tool

1. Open Program.cs. It should look like this:
   C#

• Console.WriteLine("Hello, World!");
  

  The preceding function is run at the start of the application and outputs a string to the console. Let’s add Humanizer and manipulate data and write it to the console.

• Install the Humanizer library by running the following command:
  .NET CLI

dotnet add package Humanizer --version 2.7.9

Open the DotNetDependencies.csproj file and find the ItemGroup section. You should now have an entry that looks like this one:

• <ItemGroup>
      <PackageReference Include="Humanizer" Version="2.7.9" />
  </ItemGroup>
  

• Add the following content at the top of the Program.cs file to initialize Humanizer:
  C#

using Humanizer;

Your Program.cs should now look like this:

• using Humanizer;
  
  Console.WriteLine("Hello, World!");
  

• Add the following content to the Program.cs file to the bottom of file under the Console.WriteLine("Hello, World!");:
  C#

• static void HumanizeQuantities()
  {
      Console.WriteLine("case".ToQuantity(0));
      Console.WriteLine("case".ToQuantity(1));
      Console.WriteLine("case".ToQuantity(5));
  }
  
  static void HumanizeDates()
  {
      Console.WriteLine(DateTime.UtcNow.AddHours(-24).Humanize());
      Console.WriteLine(DateTime.UtcNow.AddHours(-2).Humanize());
      Console.WriteLine(TimeSpan.FromDays(1).Humanize());
      Console.WriteLine(TimeSpan.FromDays(16).Humanize());
  }
  

• Replace the Console.WriteLine("Hello, World!"); with the following code:
  C#

• Console.WriteLine("Quantities:");
  HumanizeQuantities();
  
  Console.WriteLine("\nDate/Time Manipulation:");
  HumanizeDates();
  

• Save the file (File > Save or CTRL + S). Run the application by running the following command in the terminal:
  .NET CLI

dotnet run

You should see the following output.

Quantities:
0 cases
1 case
5 cases

Date/Time Manipulation:
yesterday
2 hours ago
1 day
2 weeks
