System.Threading namespace is not working/appearing

Question

I am developing a novice level test xamarin test project since I am new to this technology. I need to add a static variable of type Timer using the System.Threading namespace as follows,

private static Timer timer;

But, it doesn't seem to work. I did the following things to try to make it work.

• added the nuget package manager manually
• In reference, .NET --> right click View in object browser --> select System.Threading --> clicked add reference to the selected project

Hello,

Welcome to Microsoft Q&A!

Xamarin Forms project contains System.Threading namespace. You just add the following in .cs file and please avoid adding the System.Threading with reference browser.

using System.Threading;  
    using System.Threading.Tasks;  
    using Xamarin.Forms;  
      
    namespace App58  
    {  
          
        public partial class MainPage : ContentPage  
        {  
            public MainPage()  
            {  
                InitializeComponent();  
                  
            }  
            private static Timer timer;  
        }  
    }
