所有，
我的项目 - （VS 2010 / .NET 4 / ASP.NET应用程序，我的Web应用程序作为Sitefinity应用程序存在于Sitefinity中）
我有两个版本的MongoDB程序集。我想在我的Web应用程序中并排运行这些。这是我的设置：
\bin\AuxFiles\[1.8.3.9] assemblies
\bin\[1.4.x.x] assemblies
网络配置：
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="MongoDB.Bson" publicKeyToken="f686731cfb9cc103" culture="neutral" />
<codeBase version="1.4.2.4500" href="bin\MongoDB.Bson.dll" />
<codeBase version="1.8.3.9" href="bin\AuxFiles\MongoDB.Bson.dll" />
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="MongoDB.Driver" publicKeyToken="f686731cfb9cc103" culture="neutral" />
<codeBase version="1.4.2.4500" href="bin\MongoDB.Driver.dll" />
<codeBase version="1.8.3.9" href="bin\AuxFiles\MongoDB.Driver.dll" />
</dependentAssembly>
</assemblyBinding>
应用程序启动时，默认情况下会加载1.4.x.x程序集。当我转到使用1.8.3.9版程序集的页面时，我收到一个错误：
Server Error in '/' Application.

更新1：
我试图将我的新1.8.xx程序集从MongoDB.Driver.dll重命名为MongoDB.Driver.exe，因此文件可以在同一目录下共存（较旧的程序集具有扩展名.dll，新版本的程序集具有扩展名.exe）但是加载程序似乎没有提取集会。我的理解是，加载器总是首先尝试.dlls，然后尝试.exes秒。我有点不解。
更新2：
我已经创建了一个控制台应用程序w /我的双重引用和你在这里看到的应用程序配置条目完全相同的设置 - 并且应用程序工作，它执行2个版本的Mongo dll。问题是，为什么这个设置在我的Web应用程序中不起作用？我的目录错了吗？如果你看下面的探测程序集，它永远不会检查我的AuxFiles目录，它似乎忽略了我在web.config中并行执行的配置。

发现了这个问题，但我不确定这个解决方案的细节。 web.config文件具有'configuration'根元素w /以下命名空间声明 - 'xmlns=http://schemas.microsoft.com/.NetConfiguration/v2.0'。
根元素很好，但指定的命名空间导致我的'runtime'元素被忽略。从配置元素中删除命名空间可以修复所有问题。
发现问题：
web.config文件中的“configuration”根元素包含以下名称空间声明 - “xmlns = http://schemas.microsoft.com/.NetConfiguration/v2.0”。从配置元素中删除命名空间可以修复所有问题。
为什么ns？它更像是VS中的任何错误，并且实际上没有任何真正的目的，但是搞乱了你的智能感知，在我的情况下是运行时配置。了解更多信息：http://weblogs.asp.net/scottgu/archive/2005/12/02/432077.aspx
