Question

我对Google Calendar Api有疑问。当Install-Package Google.Apis.Calendar.v3正常工作时，无法安装Google.Apis和Google.Apis.Auth包。项目在.net 4.0。

Install-Package : Unable to uninstall 'Microsoft.Bcl.Build 1.0.21' because 'Microsoft.Bcl 1.1.10' depends on it.

Install-Package : Could not install package 'Google.Apis.Core 1.13.1'. You are trying to install this package into a projec
t that targets '.NETFramework,Version=v4.0', but the package does not contain any assembly references or content files that
 are compatible with that framework. For more information, contact the package author.

PM> Install-Package Google.Apis.Calendar.v3
'Google.Apis.Calendar.v3 1.13.1.509' already installed.

主要参考＆＃34; Google.Apis.Calendar.v3，Version = 1.13.1.509，Culture = neutral，PublicKeyToken = 4b01fa6e34db77ab，processorArchitecture = MSIL＆＃34;无法解决，因为它对框架程序集具有间接依赖性; System.Net.Http，Version = 1.5.0.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a＆＃34;这在目前的目标框架中无法解决。＆＃34; .NETFramework，版本= 4.0版＆＃34 ;.要解决此问题，请删除引用＆＃34; Google.Apis.Calendar.v3，Version = 1.13.1.509，Culture = neutral，PublicKeyToken = 4b01fa6e34db77ab，processorArchitecture = MSIL＆＃34;或者将您的应用程序重新定位到包含＆＃34; System.Net.Http，Version = 1.5.0.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a＆＃34;。

的框架版本。

将您的项目升级到.Net framework 4.5，它应该可以运行。错误消息可以准确地告诉您问题所在。

无法安装软件包＆＃39; Google.Apis.Core 1.13.1＆＃39;。你正试图将此包安装到目标项目中＆＃39; .NETFramework，Version = v4.0＆＃39;，但包不包含任何 与兼容的程序集引用或内容文件的框架

如果您查看NuGet页面Google APIs Core Client Library 1.13.1
