自托管owin Web API的MEF组件 [英] MEF component for self hosted owin web api

问题描述

我正在尝试创建一个MEF组件，该组件将在Windows服务中使用并将运行自托管的Web api.

I'm trying to create a MEF component that will be used in a windows service and will run a selfhosted web api.

当我使用Newtonsoft.Json作为委托消息处理程序并且当前使用v8.0.3时，加载库的依赖项时遇到问题.但是，System.Net.Http.Formatting.dll文件需要版本6.0.0.0，这是我的MEF组件 无法加载.

I'm having a problem loading the dependencies of the library as I use Newtonsoft.Json for a delegated message handler and currently use v8.0.3.  However, the System.Net.Http.Formatting.dll file requires version 6.0.0.0 and this is were my MEF component fails to load.

我有一个app.config文件，它确实在bin目录中创建了正确的.config文件，并且我已将其复制到插件所在的扩展目录中，并且它具有我认为是正确的重定向条目:

I have an app.config file that does create the proper .config file in the bin directory and I have copied to the extensions directory where the plugin resides and it has what I think is the proper redirect entry:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-8.0.0.0" newVersion="8.0.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

但是，这似乎无法解决问题，并且我不断遇到相同的错误.  有什么我想念的吗?

However this does not seem to solve  the issue and I keep getting the same error.  Is there something I missing?

谢谢

FernandoCBI，

Hi FernandoCBI,

谢谢您在这里发布.

对于您的问题，它是Newtonsoft.Json需要6.0的版本吗?

For your question, is it the version of Newtonsoft.Json require 6.0?

您可以单击工具">"NuGet程序包管理器">管理解决方案的NuGet程序包".然后选择所需的版本.

You could click Tools>NuGet Package Manager>Manage NuGet Packages for Solution. And choose the version you want.

我希望这会有所帮助.
