C# XAML设计器System.TypeLoadException

我几乎要发疯了，因为从XAML设计师那里得到消息，不知道该怎么办

正如你在网上看到的

Could not load type 'Mocks.Libraries_Collection_Classes_Storages_0_229157595

在Libraries.Collection命名空间中有一个名为Storages的类。从当前项目中删除引用库.Collection时，如下所示：

然后xaml设计器开始工作

当我添加库时。再次添加集合库： 然后打开XAML设计器，错误再次出现：

类storages类看起来像：

using System.Collections.Generic;
using System.Collections.ObjectModel;

namespace Libraries.Collection.Classes
{
    public class Storages : ObservableCollection<Storage>
    {
        public Storages()
        {
        }

        public Storages(IEnumerable<Storage> coll) : base(coll)
        {
        }
    }
}

问题在于xaml设计器。下一步我该怎么做？

仔细阅读您的问题后，我编辑了此答案

在较旧的VS版本中，我曾经遇到过类似的异常，但不同的是它是在运行时出现的。在我的例子中，最终的结果是GAC中已经有了一个版本的程序集。为了确定我使用的原因，这可能是你现在最好的改变，看看你的盒子里发生了什么。

首先，感谢您的建议。我确实记录了日志，请查看上面的内容，您是否可以告诉我出了什么问题。首先，请确保将程序集中的dll复制到输出路径，特别是验证引用的“复制本地”属性是否设置为true。还要确保它是在一个比您的项目兼容的平台上编译的（32位、64位或任何CPU）。我确实记录了日志，请查看上面的内容，您是否可以告诉我出了什么问题。首先，请确保将程序集中的dll复制到输出路径，特别是验证引用的“复制本地”属性是否设置为true。还要确保它是根据兼容的平台编译的，而不是您的项目（32位、64位或任何CPU）。
