Listview 不占用财产

Question

我已经创建了一个列表，它是一个属性 amnd，然后给出了列表值，但这仍然无法作为 itemsource 放置在列表视图中，我不知道如何解决这个问题并获得结果有没有人可以告诉我我在这里做错了什么？我将数据上下文放在主窗口中

XAML

<Window x:Class="CRM.MainWindow"
            xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
            xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
            xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
            xmlns:local="clr-namespace:CRM"
            mc:Ignorable="d"
            Title="MainWindow" Height="1080" Width="1920">
        <Grid>
            <Grid.ColumnDefinitions>
                <ColumnDefinition/>
                <ColumnDefinition Width="0*"/>
            </Grid.ColumnDefinitions>
            <ListView ItemsSource="{Binding tickets}" Margin="0,10,1075,0" MaxWidth="990"/>
        </Grid>
    </Window>

主视图模型：

using API.Objects;
using API.ViewModels;
using System;
using System.Collections.Generic;
using System.Text;

namespace API.ViewModels
{
    public class MainViewModel : BaseViewModel 
    {
        int Counter{ get; set; }
        List<TicketO> tickets { get; set;}



        public MainViewModel()
        {
            TicketO ticket = new TicketO("Jens", "Svensson", "jenson1234@live.se", "0767942768", "This is working but my box is not", 500); 

            tickets.Add(ticket);


        }






    }
}

    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            this.DataContext = new MainViewModel(); 
        }
    }
}
