WPF ListView/GridView Binding

问题

I am attempting to make a simple VS 2017 Extension that is taking a object and displaying it. I have the data coming back and displaying the json in a text box, so I know the data is coming back correctly. But for some reason the gv is just showing the word "id" twice, as their are two records in the dataset. I have tried so many things I'm loosing track. Plus the documentation seems to be all over the place.

I believe there could be at least 2 issues here...

1) XAML the "Bindings"

2) Binding or adding the data to the LV?

Any help with this would be greatly appreciated!

XAML

<UserControl x:Class="DoWork.AllWorkVSControl"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

             Name="MyToolWindow">
    <Grid>
        <StackPanel Orientation="Vertical">
            <TextBlock Margin="10" HorizontalAlignment="Center">AllWorkVS</TextBlock>
            <Button Content="Click me!" Click="button1_Click" Width="120" Height="80" Name="button1"/>
            <TextBox Height="200" TextWrapping="Wrap" Name="txtJson"/>
            <ListView x:Name="LvIssues">
                <ListView.View>
                    <GridView>
                        <GridView.Columns>
                            <GridViewColumn Width="Auto" Header="Id"  DisplayMemberBinding="{Binding Source='Id'}"></GridViewColumn>
                        </GridView.Columns>
                    </GridView>
                </ListView.View>
            </ListView>
        </StackPanel>
    </Grid>
</UserControl>

public class People
{
    public string Id { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

public partial class AllWorkVSControl : UserControl
{

    public AllWorkVSControl()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, RoutedEventArgs e)
    {
        var t = Issues.GetPeopleById("2");
        PopulateListView();
        MessageBox.Show(t);
    }

    private void PopulateListView()
    {
        var l = GetPeople();
        txtJson.Text = JsonConvert.SerializeObject(l);

        foreach (var p in l)
        {
            LvIssues.Items.Add(p);
        }
    }
}

you need to set the ListView.ItemsSource.

private void PopulateListView()
{
    var l = GetPeople();
    txtJson.Text = JsonConvert.SerializeObject(l);

    LvIssues.ItemsSource= l;
}

<ListView x:Name="LvIssues">
            <ListView.View>
                <GridView>
                    <GridView.Columns>
                        <GridViewColumn Width="Auto" Header="Id"  DisplayMemberBinding="{Binding Id}"></GridViewColumn>
                    </GridView.Columns>
                </GridView>
            </ListView.View>
        </ListView>
