加载共享类库时出错

Question

我有一个 ASP.NET 站点/WPF/Windows 手机应用程序，它们都使用三个链接项目。在数据项目 (Myproject.DAL) 中，我使用了对 System.Data.SQLite 和 ICSharpCode.SharpZipLib 的引用。后者似乎是为 VS 中的运行时版本 2.0 编译的，即使我下载的是 4.0 版本（可能是我的误解）。

当我尝试加载 ASP.NET 4 站点时，出现错误：

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.

我记得过去遇到过这个问题，它是由 System.Data.SQLite 库引起的，它是一个 x86 二进制文件。我已经更新了，这绝对不是原因。所有项目都设置为作为 .NET 4 x86 运行。有什么办法可以找出造成这种情况的实际原因吗？我猜肯定是某个地方的 DLL 有问题，但 MSBuild 似乎没有报告任何问题。

尽管打开了 Fusion 日志记录，但我得到的唯一神秘错误是：

=== Pre-bind state information ===
LOG: User = IIS APPPOOL\CP

WRN: Partial binding information was supplied for an assembly:
WRN: Assembly Name: ChickenPing.DAL | Domain ID: 9
WRN: A partial bind occurs when only part of the assembly display name is provided.
WRN: This might result in the binder loading an incorrect assembly.
WRN: It is recommended to provide a fully specified textual identity for the assembly,
WRN: that consists of the simple name, version, culture, and public key token.

这并没有真正提供太多洞察力。

这原来是一个设置——在应用程序池设置的“高级设置”部分中的“启用 32 位应用程序”。
