How to configure SQLite to run with NHibernate where assembly resolves System.Data.SQLite?

Question

I am using the latest NHibernate 2.1.0Beta2. I'm trying to unit test with SQLite and have the configuration set up as:

        Dictionary<string, string> properties = new Dictionary<string, string>();
        properties.Add("connection.driver_class", "NHibernate.Driver.SQLite20Driver");
        properties.Add("dialect", "NHibernate.Dialect.SQLiteDialect");
        properties.Add("connection.provider", "NHibernate.Connection.DriverConnectionProvider");
        properties.Add("query.substitutions", "true=1;false=0");
        properties.Add("connection.connection_string", "Data Source=test.db;Version=3;New=True;");
        properties.Add("proxyfactory.factory_class",
                       "NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu");

        configuration = new Configuration();
        configuration.SetProperties(properties);

When I try to run it, I get the following error:

NHibernate.HibernateException: The IDbCommand and IDbConnection implementation in the  assembly System.Data.SQLite could not be found. Ensure that the assembly System.Data.SQLite is located in the application directory or in the Global Assembly Cache. If the assembly is in the GAC, use <qualifyAssembly/> element in the application configuration file to specify the full name of the assembly.
at NHibernate.Driver.ReflectionBasedDriver..ctor(String driverAssemblyName, String connectionTypeName, String commandTypeName) in c:\CSharp\NH\nhibernate\src\NHibernate\Driver\ReflectionBasedDriver.cs: line 26
at NHibernate.Driver.SQLite20Driver..ctor() in c:\CSharp\NH\nhibernate\src\NHibernate\Driver\SQLite20Driver.cs: line 28 

So it looks like I need to reference the assembly directly. How would I do this so I don't get this error anymore?

I downloaded the latest assembly from here: http://sourceforge.net/projects/sqlite-dotnet2.

Answer 1

Are you running 64-bit Windows?

When looking around Google, I saw several posts commenting that the SQLite dll file is built for x86, not x64.

See this post: http://codetripper.wordpress.com/2009/01/03/using-sqlite-on-vista-64-bit/

Edit: I'm not sure as of when, but I noticed today that the latest releases of System.Data.SQLite include the x64 dll. The x64 .dll is in \bin\x64.

After adding the reference to the System.Data.SQLite assembly, I had to set copy local to true (select the assembly reference in VS and go to properties) so that the assembly is copied to the bin directory.
