无法在NUnit中使用nHibernate加载DLL'SQLite.Interop.dll'

Question

I've installed FluentNHibernate and System.Data.SQLite.MSIL with Nuget.

I wrote some unit tests and tried to execute them. But my test setup is failing miserably:

Probel.NDoctor.Statistics.UnitTests.SQLite.ChartQueryTest (TestFixtureSetUp): SetUp : FluentNHibernate.Cfg.FluentConfigurationException : An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail.

----> System.Reflection.TargetInvocationException : Exception has been thrown by the target of an invocation. ----> System.DllNotFoundException : Unable to load DLL 'SQLite.Interop.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

Well, Nuget didn't import SQLite.Interop.dll when I installed the package System.Data.SQLite.MSIL ...

I'm using:

• NHibernate 3.3.1.4000 (installed when I installed FluentNHibernate 1.3.0.733 )
• System.Data.SQLite.MSIL
• NUnit 2.6.2.12296
• Visual Studio 2010

Note all these dll import was dont via Nuget.

The 'SQLite.Interop.dll' is contained in the System.Data.SQLite Nuget package. The System.Data.SQLite.MSIL package you installed only contains the ADO.NET provider. Just uninstall System.Data.SQLite.MSIL and install System.Data.SQLite which has the ADO.NET provider and the unmanaged library. That should fix your issue.
