【问题描述】：

我知道这似乎是一个老问题，但我认为历史上没有人遇到过同样的问题。

我向 Dynamics 365 版本 9 发送了一个请求到IOrganizationService.Create，并且测试似乎在十几次之后是可重复的。在某个时候它不再起作用了，我必须重新启动美元。

我得到的错误是：

Exception detail:Error during HTTP request to https://xxxxxxxx.api.crm4.dynamics.com/XRMServices/2011/Organization.svc/web?SDKClientVersion=9.0.9002.0. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server.  
Server stack trace:

   in CustomHostedControls.HiddenController.DoAction(RequestActionEventArgs args)
   in Microsoft.Uii.Csr.Aif.HostedApplication.HostedWpfControl.HandleRequestAction(Object sender, RequestActionEventArgs args)

我已经验证了所有这些条件：

测试机为 Windows 7 Professional Version 6.1 Build 7601 Service Pack 1, 64 bit
SchUseStrongCrypto 在HKLM\SOFTWARE\Microsoft\.NETFramework\v4.0.30319 和HKLM\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319 下均设置为1
exe 是 Unified Service Desk 3.2，针对“.NETFramework,Version=v4.6.2”
此软件已编译为针对“.NETFramework,Version=v4.5.2”的 dll
在我的UnifiedServiceDesk.exe.config 我有：<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.2"/>

我还应该检查什么？

谢谢

【解决方案1】：

在代码的某个地方我有这样一行：

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls;

解决了这个问题：

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls | SecurityProtocolType.Tls12;

无论如何，最佳解决方案是隔离应用程序域中的代码。
