我正在使用 VS2017 开发应用程序C#，.Net Framework 4.6.2.

我有一个类库，我为它安装了Geocoding Core和Googlenuget 包。那些是Net Standard 1.3图书馆。

这增加了对其他几个库的依赖，以及System.Xml.XPath.

虽然，在运行时，当我尝试访问其中一种Geocoding.net方法时

var geocoder = new GoogleGeocoder("key");

var task = geocoder.GeocodeAsync(searchString);

task.Wait()

我收到这个错误

System.AggregateException occurred
  HResult=0x80131500
  Message=One or more errors occurred.
  Source=mscorlib
  StackTrace:

Inner Exception 1:
GoogleGeocodingException: There was an error processing the geocoding request. See Status or InnerException for more information.

Inner Exception 2:
FileLoadException: Could not load file or assembly 'System.Xml.XPath, Version=4.0.2.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Inner Exception 3:
FileLoadException: Could not load file or assembly 'System.Xml.XPath, Version=4.0.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

我不知道该怎么做。System.XML.XPath 文件位于输出文件夹中。

我尝试添加程序集绑定重定向：

  <dependentAssembly>
    <assemblyIdentity name="System.Xml.XPath" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-4.0.2.0" newVersion="4.0.2.0" />
  </dependentAssembly>

和这个

  <dependentAssembly>
    <assemblyIdentity name="System.Xml.XPath" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-4.0.2.0" newVersion="4.0.1.0" />
  </dependentAssembly>

似乎没有任何效果。我总是收到这个错误。

这是带有绑定重定向的融合日志：

这是没有绑定重定向的融合日志：

如果这是一个 Asp.Net 项目，请将 System.Xml.Xpath nuget 包安装到 Web 项目。我遇到了这个问题，因为我将地理编码库安装到了我的服务项目（与我的 API 控制器分开的项目）。我不得不手动将 Xpath nuget 安装到 web 项目中，它解决了它。
