在machine.config中忽略.NET assemblyBinding配置

我有一种情况，我需要能够根据它们的部分名称在GAC中加载程序集。为了做到这一点我已经添加以下到我的app.config文件：

I have a situation where I need to be able to load assemblies in the GAC based on their partial names. In order to do this I have added the following to my app.config file:

<runtime>
  <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
    <qualifyAssembly partialName="MyAssembly"
                     fullName= "MyAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=0123456789abcdef"/>
  </assemblyBinding>
</runtime>

这完全符合我的想法。但是，如果我在我的machine.config文件中放置相同的元素，它似乎被忽略，我尝试加载MyAssembly时得到FileNotFoundExceptions。

This works exactly the way I want it to. However, if I place the same element in my machine.config file, it seems to be ignored, and I get FileNotFoundExceptions when trying to load MyAssembly.

以下是当元素在我的app.config中，并且绑定成功：

The following is the assembly binding log when the element is in my app.config, and the bind succeeds:

LOG: This bind starts in default load context.
LOG: Using application configuration file: C:\Documents and Settings\jon_scheiding\My Documents\Source\Testing\Test Projects 1\Cmd\bin\Debug\Testers.Cmd.vshost.exe.config
LOG: Using machine configuration file from C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\config\machine.config.
LOG: Partial reference qualified from config file. New reference: MyAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=0123456789abcdef.
LOG: Post-policy reference: MyAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=0123456789abcdef
LOG: Found assembly by looking in the GAC.
LOG: Binding succeeds. Returns assembly from C:\WINDOWS\assembly\GAC_MSIL\MyAssembly\1.0.0.0__b20f4683c1030dbd\MyAssembly.dll.
LOG: Assembly is loaded in default load context.

对比我的配置在machine.config中的日志， ：

Contrast that with the log when my configuration is in machine.config, and the bind fails:

LOG: This bind starts in default load context.
LOG: Using application configuration file: C:\Documents and Settings\jon_scheiding\My Documents\Source\Testing\Test Projects 1\Cmd\bin\Debug\Testers.Cmd.vshost.exe.config
LOG: Using machine configuration file from C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\config\machine.config.
LOG: Policy not being applied to reference at this time (private, custom, partial, or location-based assembly bind).
LOG: Attempting download of new URL file:///C:/Documents and Settings/jon_scheiding/My Documents/Source/Testing/Test Projects 1/Cmd/bin/Debug/MyAssembly.DLL.
LOG: Attempting download of new URL file:///C:/Documents and Settings/jon_scheiding/My Documents/Source/Testing/Test Projects 1/Cmd/bin/Debug/MyAssembly/MyAssembly.DLL.
LOG: Attempting download of new URL file:///C:/Documents and Settings/jon_scheiding/My Documents/Source/Testing/Test Projects 1/Cmd/bin/Debug/MyAssembly.EXE.
LOG: Attempting download of new URL file:///C:/Documents and Settings/jon_scheiding/My Documents/Source/Testing/Test Projects 1/Cmd/bin/Debug/MyAssembly/MyAssembly.EXE.
LOG: All probing URLs attempted and failed.

问题似乎是第四行，政策目前不适用于参考。

The problem seems to be the fourth line, "Policy not being applied to reference at this time." However, I can find very little documentation on what this message means, or how to address it.

如何让框架识别我的<运行时>元素？

How can I get the framework to recognize my <runtime> element?

提前感谢！
