.net core 保存到Raven时发生异常

在我们的一个环境中，我试图将实体保存到Raven时遇到异常

详情如下:

应用程序目标框架：.NET核心2.1

RavenDB.Client版本：4.1.2

服务器上安装的.Net核心运行时和主机包：

2.1.3

2.1.6

2.2.0

（我们安装了多个版本，因为它是一个共享环境，托管了多个应用程序）

有趣的是，该应用程序在一台非常相似的机器上运行得非常好，安装了相同的设置和相同的框架。我不确定是什么导致了这只乌鸦的失败。非常感谢任何指针。

看起来像System.Runtime.CompilerServices.Unsafe没有正确安装

试试看：

1.安装和使用最新的RavenDB客户端软件包-或-

2.尝试从手动安装

---

在闲逛了一天多之后。我可以通过以下设置在本地计算机上重现该问题：

• 未安装DOTNET Core SDK

• 已为

  .NET Core 2.1.3

  和

  安装.NET Core托管和运行时.NET Core 2.2.0

如果我的机器上也安装了

.netcore2.1.6

托管和运行时（无论是否安装

2.1.3

），那么问题就消失了

这让我相信，在受影响的环境上安装

.NETCore2.1.6

在某种程度上是损坏的。所以我卸载并重新安装了.NETCore2.1.6托管和运行时，神奇地解决了这个问题

---

然而，这让我们的IT团队感到有些紧张和不安，因为他们现在觉得托管和运行时不再可信。您实际上是在黑暗中拍摄，遇到此类问题。

Hi@danielle，raven dB客户端版本包安装正确。包

System.Runtime.Compiler.Unsafe

是RavenDb的依赖项。我不知道为什么我需要手动安装。我希望它能像预期的那样开箱即用，就像它在一台机器上做的那样，但在另一台机器上却做不到一样。
