上午整合谷歌压延机使用谷歌API版本3，使用的NuGet包安装，包装Google.Apis.Calendar.v3 ，也指这个链接。在运行Web应用程序时收到错误为：

Am on integrating google calander using google api version 3, using NuGet package Install-Package Google.Apis.Calendar.v3 and also referring this link. while running the web application am getting the error as :

在网络配置文件正在使用此为：

the web config file am using for this is:

<configuration>
  <system.web>
    <compilation debug="true" strict="false" explicit="true" targetFramework="4.0" />
  </system.web>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>

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

包配置是这样的：

the package config is like :

<?xml version="1.0" encoding="utf-8"?>

  <package id="Google.Apis" version="1.9.0" targetFramework="net40" />

做，即意味着该错误是在 DLL 我是指？

does it means the error is in the dll i was referring?

推荐答案

有你的NuGet安装微软HTTP客户端库？这可能是这个问题。

Have you installed the "Microsoft Http Client Libraries" from Nuget? This might be the issue.

PM> Install-Package Microsoft.Net.Http
