Package manager

Install-Package rox-server

Table 1. Commands to add the ROX package to your application
Type of platform	Command to run
CLI	`dotnet add package rox-server`
Package manager	`Install-Package rox-server`

Add the following code to your .NET/C# application:

Your SDK key is a unique environment identifier. During SDK installation, the SDK key is displayed within the Rox.setup call.

using Io.Rollout.Rox.Server;
using Io.Rollout.Rox.Core.Entities;
using Io.Rollout.Rox.Server.Flags;
using System;
using System.Threading.Tasks;


namespace dotnet
{
// Create a Roxflag in the Flag continer class
public class Flags : IRoxContainer {
public RoxFlag enableTutorial = new RoxFlag(false);
public RoxString titleColors = new RoxString("White", new String[] {"White", "Blue", "Green"});
public RoxInt titleSize = new RoxInt(12, new int[] {12, 14, 18});
public RoxDouble specialNumbers = new RoxDouble(3.14, new double[] { 2.71, 0.577 });
}

class Program
{
    static async Task Main(string[] args)
    {
        Flags flags = new Flags();

        // Register the flag container
        Rox.Register("", flags);

        var options = new RoxOptions(new RoxOptions.RoxOptionsBuilder {});

        // Set the environment key
        await Rox.Setup("<your-SDK-key>", options);(1)

        // Boolean flag example
        Console.WriteLine("enableTutorial " + flags.enableTutorial.IsEnabled());

        // string flag example
        Console.WriteLine("titleColors value is " + flags.titleColors.GetValue());

        // int flag example
        Console.WriteLine("titleSize value is " + flags.titleSize.GetValue());

        // double flag example
        Console.WriteLine("specialNumbers value is " + flags.specialNumbers.GetValue());
    }

1	The platform provides the unique SDK key for your environment at the `<your-SDK-key>` location within the `Rox.setup` call.

Run your application and then select TEST INTEGRATION to confirm a successful connection.

After running the application, a default flag is automatically added to your feature flag list.

You have installed an SDK and created flags in your application.

Refer to the SDK reference for more information.
