.net – Dll不复制到bin文件夹

我有一个Devart DLL没有被复制到我的web应用程序的bin文件夹的问题.我有一个引用projectA的web应用程序项目. ProjectA引用projectB. Devart Dlls在projectB中使用,并且在构建期间不会被复制到Web应用程序项目bin文件夹中. ProjectB还引用了EL Unity dll,它们正在被正确复制.所讨论的所有Dll都物理上位于projectB中的文件夹中,这是参考点的位置. (我没有指向GAC的引用)

正确复制的dll是Microsoft.Practices.Unity,Microsoft.Practices.Unity.Configuration和Microsoft.Practices.ServiceLocation.

未正确复制的dll是Devart.Data,Devart.Data.Oracle和Devart.Data.Oracle.Design.

这是每个dll的参考资料……

还有谁有相同的问题吗？我做错了吗？谢谢

我打开了一个文件监视器,观察了visual studio加载引用的位置,对于Unity来说,它是从我指定的位置获取dll.但是,对于Devart dll来说,它正在寻找GAC！ Devart dlls能以某种方式造成这种情况吗？
