ReactiveUI 的最小可运行示例 - 不是运行

Question

我想为我的 ReactiveUI 问题生成一个 MWE。但是我遇到了新问题。

这是我尝试过的：

using System;
using ReactiveUI;
using ReactiveUI.Fody.Helpers;

namespace ReactivUI_Test
{
    class BarClass : ReactiveObject
    {
        [Reactive] public String Baz { get; set; } = "";
        public BarClass(String b) { Baz = b; }
        public BarClass() { Baz = "!!!"; }
        public override String ToString() { return Baz.ToString(); }
    }



    class FooClass : ReactiveObject
    {
        [Reactive] public BarClass Bar { get; set; } = new BarClass();
        public override String ToString() { return Bar.ToString(); }
    }


    class ViewModel: ReactiveObject
    {
        [Reactive] FooClass Foo { get; set; } = new FooClass();

        public ViewModel()
        {
            this.WhenAnyValue(x => x.Foo.Bar.Baz)
                 .Subscribe(x => Console.WriteLine("Hallo " + x?.ToString()));          // <- Runtime Error in this line

            Console.WriteLine("Example 1");
            this.Foo.Bar.Baz = null;
            Console.WriteLine("Example 2a");
            this.Foo.Bar = new BarClass();
            Console.WriteLine("Example 2b");
            this.Foo.Bar = new BarClass();
            Console.WriteLine("Example 3");
            this.Foo.Bar = new BarClass() { Baz = "Something" };

            Console.WriteLine("Example 4");
            this.Foo = new FooClass() ;

            Console.WriteLine("Finish");
            Console.ReadLine();
        }
    }


    class Program 
    {
        static void Main(string[] args)
        {
            ViewModel vm = new ViewModel();
        }
    }
}

我得到的运行时错误是：

TypeLoadException: The method "GetActivationForView" of Typ "ReactiveUI.ActivationForViewFetcher" der Assembly "ReactiveUI.WPF, Version=9.11.0.0, Culture=neutral, PublicKeyToken=null" has no Implementation.

Answer 1

找到的解决方案：

Nuget 数据包：ReactiveUI.WPF 未安装。

现在作为纯控制台应用程序工作。

输出：

Hallo !!!
Example 1
Hallo
Example 2a
Hallo !!!
Example 2b
Example 3
Hallo Something
Example 4
Hallo !!!
