.net-core - 保存到 Raven 时出现异常

问题描述

在我们的一个环境中尝试将实体保存到 Raven 时出现异常。

以下是详细信息：

应用程序目标框架：.NET Core 2.1

RavenDB.Client 版本：4.1.2

.Net Core Runtime and Hosting Bundle 安装在服务器上：

2.0.5

2.1.3

2.1.6

2.2.0

（我们安装了多个版本，因为它是一个托管多个应用程序的共享环境）

例外：

System.IO.FileLoadException: Could not load file or assembly 'System.Runtime.CompilerServices.Unsafe, Version=4.0.4.1, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

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，并且安装了相同的设置和相同的框架集。我不确定是什么导致这只 Raven 失败。任何指针都受到高度赞赏。

解决方案

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

尝试：

1. 安装和使用最新的 RavenDB 客户端包- 或 -

2. 尝试从 https://www.nuget.org/packages/System.Runtime.CompilerServices.Unsafe/手动安装

Install-Package System.Runtime.CompilerServices.Unsafe -Version 4.5.2
