使用已签名的程序集会导致 TargetInitationException

Question

为了让 SQL CLR 程序集在 UNSAFE 模式下工作，我必须使用密钥对该程序集进行签名。我的解决方案中的另一个项目引用该程序集以使用其某些功能。在运行时期间，当调用已签名程序集中的函数时，会引发 TargetInitationException 并显示以下消息：

无法加载文件或程序集“MyAssembly，Version=12.2.1.3，Culture=neutral，PublicKeyToken=null”或其依赖项之一。找到的程序集的清单定义与程序集引用不匹配。 （HRESULT 异常：0x80131040）

有没有办法让 .NET 加载正确的程序集/绕过异常？ 编辑： 在主程序集上运行 fusion 后，它似乎每次都会尝试使用不同的 publickeytoken 加载 MyAssembly 两次。第一次加载成功，但第二次失败。并且错误消息引用失败加载的 publickeytoken。为什么要尝试做两次？ 这是错误的文本：

The operation failed.
Bind result: hr = 0x80131040. No description available.

谢谢！

PublicKeyToken=null

它正在寻找没有强名称的程序集。您需要更新程序集引用（删除并再次添加）并重建项目。
