【问题描述】：
我的 .NET Core 3.1 应用程序连接到 Dynamics 时遇到问题。使用ServiceClient 类连接到 dynamics 时会发生该错误，但它不会一直发生，也不是随机的。我无法确定问题的原因。
这是我在应用程序尝试连接时收到的错误消息：

我在使用 .NET Framework NuGets 时看到过有关此错误的帖子，他们的解决方案不适用或无效。在动态方面我不是专家，我的主要重点是集成，所以我在这里不知所措。
当应用程序 FunctionStartup 正在运行并且存储库类和连接被启动时，会发生错误。连接是在限定的生命周期内完成的，并且相同的连接用于 Dyncamics 的所有操作（我也尝试为每个实体使用一个连接）。
到目前为止我所做的观察：
- earlybound 似乎与此问题有关，因为如果我转到 latebound 并删除 earlybound 文件，问题就会消失。但是我还有其他解决方案将早期绑定与 ServiceClient 结合使用，效果很好
- 该问题似乎也与其连接的动态实例有关，因为它不会发生在我们的 DEV 环境中，但会发生在 SIT 中
- 删除导致问题的类型会导致相同的错误，但会导致不同的类型
- 它在本地工作，直到我将它部署到我的函数应用程序时才发生崩溃
- 只需重新启动函数应用即可解决该问题
我的想法是 earlybound 与其他一些组件发生冲突，因为删除它可以解决问题。这是我正在寻找的未知组件，我的一部分正在寻找动态，因为它在一个环境而不是另一个环境中工作，并且它始终是它工作的相同环境。
对此的任何帮助或见解将不胜感激。如果对此还有其他问题，请告诉我。
谢谢！
