程序集重新编译和程序集加载问题答案

【问题描述】：

我有一个可执行文件 (Foo.exe) 和一个库 Bar.dll。两个二进制文件都是NOT 强名称签名的。 Bar.dll 库依赖于可执行文件，并以如下方式在其清单中指定：

<dependency>
    <dependentAssembly dependencyType="install" allowDelayedBinding="true" codebase="Foo.exe" size="334336">
      <assemblyIdentity name="Foo" version="1.2.3.4" language="neutral" processorArchitecture="msil" />
    </dependentAssembly>
</dependency>

我使用 ildasm 和 ilasm 从 Foo.exe -> msil -> Foo.exe 进行往返。使用 ildasm 进行反编译会生成单个 .il 文件、.res 文件和多个 .resources 文件。我以这种方式重新编译应用程序：

ilasm Foo.il /resource=Foo.res

重新编译后，应用程序可以运行并可以启动。现在的问题是依赖于可执行文件的库 Bar.dll 在重新编译后无法加载它（Foo.exe 可执行文件）。这是融合日志给我的：

   *** Assembly Binder Log Entry  (11/12/2012 @ 5:00:38 PM) ***

The operation failed.
Bind result: hr = 0x8013101b. No description available.

现在在重新编译之前文件加载成功，融合日志中唯一的区别是最后 4 行：

LOG: set name: Foo, Version=1.2.3.4, Culture=neutral, PublicKeyToken=null
WARNING: found a duplicate set during cache setup
LOG: Bind successful.
LOG: Bind is in default load context.

【解决方案1】：

ERR：从文件中提取清单导入时出错 (hr = 0x8013101b)

错误代码 8013101b 是 COR_E_NEWER_RUNTIME。换句话说，程序集需要比实际加载的版本更新的 CLR 版本。对此有一个非常简单的解释，您可能使用了错误版本的 ilasm.exe。版本 4 而不是版本 2。

请务必使用 C:\Windows\Microsoft.NET\Framework\v2.0.50727\ilasm.exe，而不是 v4.0.30319 中的那个
