.net - 程序集绑定(bind)日志中的 Post-Policy 引用是什么？

Question

试图理解这个程序集绑定(bind)失败 - 下面日志中的“后策略引用”是什么意思？

LOG: This bind starts in default load context.
LOG: Using application configuration file: E:\approot\WorkerRole.dll.config
LOG: Using host configuration file: 
LOG: Using machine configuration file from D:\Windows\Microsoft.NET\Framework64\v4.0.30319\config\machine.config.

我在我的代码引用中看不到 DLL，所以我试图弄清楚发生了什么。

Answer 1

我的理解是，“后策略引用”是发布者策略之后的程序集引用，并且在一般程序集重定向发生后。例如见 https://indexoutofrange.com/Could_not_load_file_or_assembly_or_one_of_its_dependencies/举一些例子。

如果指定了重定向，则融合日志将如下所示:

...
LOG: Using machine configuration file from C:\Windows\Microsoft.NET\Framework\v4.0.30319\config\machine.config.
LOG: Redirect found in application configuration file: 3.2.1.0 redirected to 4.0.0.0.
LOG: Post-policy reference: NLog, Version=4.0.0.0, Culture=neutral, PublicKeyToken=5120e14c03d0593c
...

关于为什么加载此 dll，那么您从日志中提取的片段缺少相关行。在上面的线上

LOG: This bind starts in default load context.

应该有类似的东西

Calling assembly : XYZ.

引用引用了 Microsoft.WindowsAzure.Diagnostics 的程序集.再次查看前面的链接以获取示例。
