c# – 最新的SQLite版本错误

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,但是针对x86的构建设置.

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)

有人知道这里出了什么问题吗？

干杯,

错误消息

Unable to copy file "...\x86\SQLite.Interop.dll" to "bin\Debug\x86\SQLite.Interop.dll". The process cannot access the file 'bin\Debug\x86\SQLite.Interop.dll' because it is being used by another process. Parties.Data.Impl.NHib.Tests

解决方法:

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SO问题的答案,但唯一对我有用的是：

>工具 – >选项 – > TestDriven.Net – >一般
>在“运行测试”下,取消选中“在测试运行之间缓存测试过程”
>重新启动Visual Studio

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.
