Question

我正在为应用程序编写加载项。 AddIn是一个Dll，它位于特定文件夹％APPDATA＆amp; / Application / AddIns / MyAddIn

所以，我有一个包含多个项目的解决方案，而MyAddInFolder包含以下文件：

IVC.Common.dll 
IVC.MaterialCatalogEditorAddIn.dll
IVC.MaterialCatalogEditor.dll

IVC.MaterialCatalogEditor.dll 中的应用程序调用方法和 IVC.MaterialCatalogEditor.dll 引用的 IVC.MaterialCatalogEditorAddIn.dll 以及 IVC.Common.dll 引用的 IVC.MaterialCatalogEditor.dll

IVC.MaterialCatalogEditor.dll 中有一个WPF froms。 xaml文件引用了 IVC.Common.dll

当我尝试从应用程序执行AddIn命令时，我收到异常“无法加载程序集 IVC.Common.dll ”

我使用了FusionLogViewer并获得了以下消息日志

这一切都好。 IVC.MaterialCatalogEditorAddIn.dll 在AddIn文件夹中调用* IVC.MaterialCatalogEditor.dll *

但下一个日志：

PresebtationFramework程序集尝试调用 IVC.Common.dll 并尝试仅从应用程序文件夹加载。

为什么一个dll尝试从AddIn文件夹加载，但是另一个dll只是尝试从应用程序文件夹加载？以及如何解决我的问题。

所有项目都有任何CPU平台目标。该应用程序是x64。

当我从测试可执行应用程序加载 IVC.MaterialCatalogEditor.dll 时，每件事都可以正常工作。

EDITED 一些代码：

IVC.MaterialCatalogEditorAddIn.dll

中的主要代码

[Transaction(TransactionMode.ReadOnly)]
    public class Command : IExternalCommand
    {
        public Result Execute(
          ExternalCommandData commandData,
          ref string message,
          ElementSet elements)
        {            

            MaterialsWindow materialsWindow =
                new MaterialsWindow();
            materialsWindow.DataContext = 
                new MaterialsViewModel();

            materialsWindow.ShowDialog();

            return Result.Succeeded;
        }
    }

MaterialsWindow类和MaterialsViewModel类位于 IVC.MaterialCatalogEditor.dll

中

debbuger在 IVC.MaterialCatalogEditor.dll 中的xaml部分显示错误：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"                    
                    xmlns:ViewModel="clr-namespace:IVC.MaterialCatalogEditor.ViewModel"
                    xmlns:Common="clr-namespace:IVC.Common;assembly=IVC.Common">
<DataTemplate
            DataType="{x:Type Common:ResourceWithCharge}">
<!-- Some data template -->
</DataTemplate>
</ResourceDictionary>

已编辑2 我编写的测试解决方案与我工作的解决方案中的结构相同。当我从测试应用程序启动它时，它没有任何错误。但是，如果我从AddIn执行它失败，“无法加载程序集Common.dll”

Test Solution

Answer 1

虽然装配探测失败了，但还有几种方法可以解决：

使用app.config文件更改程序集绑定
手柄组装通过附加到当前应用程序的AssemblyResolve来加载失败域和使用c＃代码加载必要的程序集。

Answer 2

这是因为在加载编译的XAML（BAML）时，WPF在默认上下文中使用Assembly.Load()加载了IVC.Common.dll。

您应该尝试通过以下方式编辑Revit.exe.config：

<runtime>
  <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
    <dependentAssembly>  
     <assemblyIdentity name="IVC.Common" />  
       <codeBase href="<Not sure how you can put %APPDATA% here>\Application\AddIns\MyAddIn\IVC.Common.dll"/>  
     </dependentAssembly>  
  </assemblyBinding>
</runtime>
