I got the same problem. However, finally, I can fix it. Currently, I use Visual Studio 2013 Community Edition. I just use Add->Existing Item... and browse to where the SQLite.Data.SQLite files are in (my case is 'C:\Program Files (x86)\System.Data.SQLite\2013\bin'). Please don't forget to change type of what you will include to Assembly Files (*.dll; *.pdb). Choose 'SQLite.Interop.dll' in that folder. From there and then, I can continue without any problems at all. Good luck to you all. ^_^ P.S. I create web form application. I haven't tried in window form application or others yet.

对于任何关注这个问题的人来说:

如果您使用nuget包，它会安装一个构建规则，为您执行复制。(参见System.Data.SQLite.Core.1.0.94.0\build -或任何你安装的Core版本)。

nuget安装程序会自动将规则添加到项目文件中。

但是，这仍然不能解决测试用例问题。deploymenttem (https://stackoverflow.com/a/24411049/89584)方法似乎是惟一可行的方法。

我正在做一个简单的控制台应用程序，向SQLite数据库添加一些测试数据，并得到这个错误。项目的配置是“Any CPU”。我通过将SQLite.Interop.dll复制到bin\debug文件夹来修复它。更好的方法是使用@Wil的方法，但是如何为“任何CPU”配置指定该方法呢?

将x86和x64的“SQLite.Interop.dll”文件复制到调试文件夹中。这些文件应该复制到调试文件夹中的“x86”和“x64”文件夹中。

我不知道这是否是一个好的答案，但我能够通过在AppDomain下以“本地系统”的身份运行我的应用程序来解决这个问题。
