从.NET 3.5到4.0：Web应用程序崩溃，因为没有发现未使用的组件

一个网站我正在使用一个第三方组件，让我们说A.DLL。本届大会还加载了一些操作的另一个程序集B。使用我的网站做了一个并不需要b。在所有的，而我没有B.DLL。

A website I'm working on is using a third-party assembly, let's say A.dll. This assembly A also loads another assembly B for some operations. The use that my website makes out of A doesn't require B at all, and I don't have B.dll.

这是从来没有当我是打靶.NET 3.5中的问题，但现在我想移动到.NET 4中，我得到一个错误。当我认为我的网站在浏览器中，我得到：无法加载文件或程序集B.DLL[...]。如果我把B.DLL在bin目录中，它工作正常。

This was never a problem when I was targetting .NET 3.5, but now that I'm trying to move to .NET 4, I get an error. When I view my website in the browser, I get: "Could not load file or assembly 'B.dll' [...]". If I put B.dll in the bin directory, it works fine.

不过，我不希望部署B.DLL，我不知道是什么让.NET 4尝试加载该程序集，而该网站不使用的需要的任何功能。我感到迷惑，同样的code正常工作的.NET 3.5。我猜它会尝试加载的所有程序集提前，即使它不会被使用。我在寻找一些配置和编译器标志，该标志将prevent此行为。任何指针？

However, I don't want to deploy B.dll and I don't know what makes .NET 4 try to load that assembly while the website does not use any function of A that requires it. I'm mystified as the same code works fine on .NET 3.5. I'm guessing that it tries to load all assemblies in advance, even if it won't be used. I'm looking for some configuration or compiler flag that would prevent this behavior. Any pointers?

我想通过省略的细节和原因，我不希望B部署，等等。请让我知道，如果我提供的资料没有给出一个明确的拍摄问题，以简化我的问题。谢谢！

I tried to simplify my problem by omitting details and reasons why I don't want B deployed, etc. Please let me know if the information I've given doesn't give a clear shot of the problem. Thanks!
