加载共享类库时出错

Question

我有一个ASP.NET网站/ WPF/Windows手机应用程序，它们都使用三个链接的项目。在数据项目（Myproject.DAL）中，我使用对System.Data.SQLite和ICSharpCode.SharpZipLib的引用。后者似乎被编译为运行在VS版本2.0，即使我下载了4.0版本（也许是我的误解）。

当我尝试加载ASP.NET 4个网站，我得到一个错误：

Could not load file or assembly 'ChickenPing.DAL' or one of its dependencies. An attempt was made to load a program with an incorrect format. 

我记得有过去这个问题，它由System.Data引起.SQLite库，它是一个x86二进制文件。我已更新，这绝对不是原因。所有项目都设置为以.NET 4 x86运行。有什么方法可以追踪这个实际的原因吗？我猜测肯定是某个地方的问题DLL，但MSBuild似乎没有报告任何问题。

尽管开启融合记录，唯一神秘的错误我得到的是：

=== Pre-bind state information ===

(Partial) 
WRN: Partial binding information was supplied for an assembly:

这并没有真正提供很大的启示。

原来这是一个设置 - “启用32位应用程序”在应用程序池设置的“高级设置”部分。
