DataGrid: [WinUI] ArgumentOutOfRange exception when column are added manually and IWindowCreator approach is used

We have discovered an error when you implement IWindowCreator and create custom window and connect viewmodel via AddSingleton approach

This is the stack-trace:

Workaround:

Subscribe to the Page.Loaded event and define the columns in the event:

private void ContentPage_Loaded(object sender, EventArgs e)
    {
        this.dataGrid.Columns.Add(new DataGridTextColumn()
        {
            PropertyName = "Name",
        });
        this.dataGrid.Columns.Add(new DataGridTextColumn()
        {
            PropertyName = "Address",
        });
        this.dataGrid.Columns.Add(new DataGridDateColumn()
        {
            PropertyName = "Date",
        });
    }
