我在Xamarin中使用HttpClient请求使用TLS 1.2进行https，我得到如下错误;

有谁知道如何解决此问题。我听说Xamarin是Mono 2.0中TLS的错误。 非常感谢

在发布版本中发现此错误，但未在Debug版本中发现。

对于Xamarin + VS，可以在Android项目属性中设置TLS 1.2（右键单击Android项目＆gt;底部属性）＆gt; Android选项＆gt;滚动到底部，单击“高级”＆gt;底部，SSL / TLS实现。在那里你找到了Native TLS 1.2 +。

我不知道通用的跨平台Xamarin解决方案。

Xamarin可选择通过App Transport Security（https://developer.xamarin.com/guides/ios/platform_features/introduction_to_ios9/ats/）支持适用于iOS9的TLS 1.2：

  

与NSUrlConnection，CFUrl或NSUrlSession建立的任何连接都将   默认情况下，在为iOS 9和OS X 10.11构建的应用程序中使用ATS（El   匹）。   ATS将对所有互联网强制执行以下要求   连接：所有连接密码必须使用前向保密。该   传输层安全性（TLS）协议必须是版本1.2或   更大。至少一个带有2048位或者2048位的SHA256指纹   更大的RSA密钥，或256位或更大的椭圆曲线（ECC）密钥必须   用于所有证书。

自2014年4月https://xamarin.uservoice.com/forums/144858-xamarin-platform-suggestions/suggestions/5758129-implement-tls-1-2以来，社区一直在努力填补这一空白。

目前，Mono release 4.8.0

支持TLS 1.2
