json.net - 发布版本中 PostSharp 中的 AssemblyLoadException

Question

我有几个项目都包含 json.net 6.0.3 NuGet 包。当我添加时:

using Newtonsoft.Json;

构建时出现以下错误:

我无法在项目中找到对“'newtonsoft.json，version=4.5.0.0”的任何引用，不确定为什么要查找它。

我尝试将“Build Host”PostSharp 项目属性设置为托管，但仍然遇到相同的异常。

当某些第 3 方库引用旧版本的程序集(在本例中为 Newtonsoft.Json)时，通常会发生这种情况。通过在 web.config/app.config 文件中指定绑定(bind)重定向来解决该问题。

<dependentAssembly>
  <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral"/>
  <bindingRedirect oldVersion="0.0.0.0-6.0.3.0" newVersion="6.0.3.0"/>
</dependentAssembly>

但是，您还需要告诉 PostSharp 到哪里寻找绑定(bind)重定向配置。您可以通过在 *.csproj 文件中设置 PostSharpHostConfigurationFile 属性来执行此操作:

<PropertyGroup>
  <PostSharpHostConfigurationFile>web.config</PostSharpHostConfigurationFile>
</PropertyGroup>
