刚刚通过Nuget将我的SQLite dll更新为v1.0.81.0,我收到的错误如下所示。首次成功执行一次或多次(不确定)后会发生这种情况。环境是x64计算机上的vs2010,但其构建设置为x86。
我使用SQLite对我的NHibernate映射进行单元测试。在过去经常发现SQLite有点“胡思乱想”,我不愿意弄乱工作单元测试夹具(见下文)
任何人都知道这里出了什么问题?
干杯,

我在使用VS2010和TestDriven.Net的SQLite 1.0.88.0时遇到了这个问题。我尝试了几个问题的答案,但唯一对我有用的是:
您现在应该能够运行测试,调试测试,重建等,而无需重新启动进程或Visual Studio。

将SQLite dll“复制到输出目录”更改为“如果更新则复制”。 (您可能需要在更改属性后重新启动VS)
