C# 无法加载文件或程序集'；System.Net.Http，版本=2.2.29.0'；

我正在使用VisualStudio2010构建VSTO Outlook外接程序。我没有安装Nuget软件包管理器。在Outlook中运行外接程序时，出现异常：

无法加载文件或程序集'System.Net.Http，Version=2.2.29.0'

我只是从GitHub克隆了原始项目。当我使用VisualStudio在调试中运行它时，它工作得很好。但是，一旦我发布到setup.exe并安装，就会出现上述问题。已添加对

System.Net.Http

的引用

Outlook 2007版的我的

app.config

文件是：

<?xml version="1.0"?>
<configuration>
  <configSections>
    <sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
      <section name="Outlook2007.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" />
    </sectionGroup>
  </configSections>
  <appSettings>
  </appSettings>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
        <bindingRedirect oldVersion="0.0.0.0-2.2.29.0" newVersion="2.2.29.0"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
<startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/></startup><userSettings>
    <PluginOutlook2007.Properties.Settings>
      <setting name="TokenSettingNeed" serializeAs="String">
        <value>else imported dll settings don t work</value>
      </setting>
    </PluginOutlook2007.Properties.Settings>
  </userSettings>
</configuration>

然后b同一解决方案中还有第三个项目（其业务逻辑由2007和2010项目与下面的

app.config

共享）。第三个项目实际使用

System.Net.Http

命名空间：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <configSections>
        <sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
            <section name="PluginOutlookCommon.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" />
        </sectionGroup>
    </configSections>
    <userSettings>
      // some stuff here
    </userSettings>
<startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0" /></startup>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">

      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

//这里有些东西

我通过注释掉

<dependentAssembly>
    <assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-2.2.29.0" newVersion="2.2.29.0" />
    </dependentAssembly>
</assemblyBinding>

app.config

文件中的一部分

<dependentAssembly>
    <assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-2.2.29.0" newVersion="2.2.29.0" />
