How to solve Operator ‘!=’ cannot be applied to operands of type ‘T’ and ‘T’

using System.Collections.Generic;

public class Test<T>
{
    public T Value
    {
         get => _Value; 
         set
         {
            // operator== is undefined for generic T; EqualityComparer solves this
            if (!EqualityComparer<T>.Default.Equals(_Value, value))
            {
                _Value = value;
            }
         }
    }
    private T _Value;
}
