Question

我有一个使用库的ASP.net WebService，它依赖于某些第三方.dll。

如果我将库的引用添加到我的webservice，我得到一个COMException，我无法加载该站点。我认为它可能与aspnet用户凭据有关，所以我尝试模拟并在machine.config中使用processModel，但似乎没有任何工作。

.dll用于与硬件通信，所以我甚至不在服务器上使用它们只是库的其他部分，有什么方法可以解决这个问题吗？

我正在使用Visual 2008 SP1和.net 3.5运行Windows XP Pro SP3。

我在想解决它的唯一方法是将库拆分为硬件和非硬件。

干杯，萨基

感谢KimGräsman让我走上正轨。

缺少该过程的原因是因为asp.net正在从％windir％\ system32而不是当前目录加载.dll。

在那里看，是.dll的一些非常旧的版本（不确定他们是谁/如何到达那里）。删除这些显示FileIOException，所以用最新的.dll替换它们似乎已经修复了它。
