Swashbuckle 更新到版本 6.5 后 Kestrel 启动错误 - 无法加载程序集“Microsoft.AspNetCore.Authentication.Abstractions”

问题描述 投票：0回答：1

我将 Swashbuckle.AspNetCore 从 4.0.1 更新到 6.5。 除了将一些类更改为 Microsoft.OpenApi.Models 挂件之外，我无需进行任何更改，并且它可以在我的本地开发计算机上运行。 将我的 Api 发布到暂存环境后，Kestrel 启动例程会抛出此错误：

Microsoft.AspNetCore.Hosting.Internal.WebHost[6]
      Application startup exception
      Could not load file or assembly 'Microsoft.AspNetCore.Authentication.Abstractions, Version=2.1.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

在安装文件夹中存在程序集，但在版本 2.2.0.18316 中，它与我更新到 6.5 之前的程序集相同，并且在我的本地计算机上也是相同的版本，一切正常。

Kestrel 启动的完整轨迹：

有什么建议吗？我错过了什么？

问题是 Api.exe.config 文件中缺少 AssemblyBinding：

<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
  <dependentAssembly>
    <assemblyIdentity name="Microsoft.AspNetCore.Authentication.Abstractions" publicKeyToken="adb9793829ddae60" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-2.2.0.0" newVersion="2.2.0.0" />
  </dependentAssembly>
</assemblyBinding>

随着 Swashbuckle.AspNetCore 更新到版本 6.5，AssemblyBindings 发生了一些更改，由于我们的部署过程中存在一些问题，这些更改在暂存环境中丢失了。

确定正确的 *.exe.config 文件已发布到临时计算机后，一切正常。
