MVVMCross，WPF，XAML "Unable to resolve the binding creator - have you initialized Windows Binding"

Question

我正在尝试使用具有两个视图和两个视图模型的 MVVMCross 制作一个简单的 WPF 应用程序。我只想让初始视图上的按钮打开第二个视图，使用 MvvmCross.BindingEx.Wpf nuget 包。这是我的 XAML 代码中的第一个标签：

<views:MvxWpfView 
         x:Class="FirstMVVMProject.WPF.Views.FirstView"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
         xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
         xmlns:views="clr-namespace:Cirrious.MvvmCross.Wpf.Views;assembly=Cirrious.MvvmCross.Wpf"
         xmlns:mvx="clr-namespace:mvx;assembly=Cirrious.MvvmCross.BindingEx.Wpf"
         mc:Ignorable="d" 
         d:DesignHeight="300" d:DesignWidth="300" >

这是按钮：

<Button Width="50" Height="50" mvx:Bi.nd="Command GoCommand"/>

这是我的视图模型class:

namespace FirstMVVMProject.Core.ViewModels{
using System.Windows.Input;

using Cirrious.MvvmCross.ViewModels;

public class FirstViewModel : MvxViewModel
{      
        private MvxCommand _goCommand;
        public ICommand GoCommand
        {
            get
            {
                _goCommand = _goCommand ?? new MvxCommand(GoToSecond);
                return _goCommand;
            }
        }

        private void GoToSecond()
        {
            base.ShowViewModel<SecondViewModel>();
        }
}
}

当我尝试运行程序时，我在这个按钮所在的行上得到一个XamlParseException，在异常快照的内部异常部分，它说

Unable to resolve the binding creator - have you initialized Windows Binding.

我什至不知道如何处理这个问题。有谁知道可能是什么问题以及我该如何解决它？

按照斯图尔特的指示，我查看了this document，其中描述了Xaml中的西藏和里约热内卢。我在 Setup.cs class.

中遗漏了这段代码

protected override void InitializeLastChance()
{
    base.InitializeLastChance();

    var builder = new MvxWindowsBindingBuilder();
    builder.DoRegistration();        
}

在我粘贴之后，一切正常。谢谢！
