NHibernate Configuration.cs File Missing

Question

I recently obtained Fluent NHibernate from GitHub (latest version), though when I instantiate an instance of FluentConfiguration while in debug mode, I get prompted for the location of NHibernate's Configuration.cs file. I've looked in NHibernate's source, and haven't been able to find it. I used Visual Studio to build from source, and am wondering if there's a chance that I may have made a mistake for doing that. Could someone point me in the right direction as how to solve this? My version is 3.2.

Update

My debugger is officially screwed - my ISession variable is timing out on the stacktrace, stating that the "function evaluation is disabled because a previous function evaluation timed out. You must continue execution to re-enable function eval."

I'll post my config file, here:

And finally, the Fluent Config

return Fluently.Configure()
                    .Database(
                       MySQLConfiguration.Standard.ConnectionString(_connectionString)
                    )
                    .Mappings(
                        m => m.FluentMappings.AddFromAssembly(Assembly.GetExecutingAssembly())
                    )
                    .BuildSessionFactory();

Answer 1

For some reason the debugger doesn't seem to be able to pinpoint exactly where something goes wrong with this. But in my experience, when VS asks you for either Configuration.cs or FluentConfiguration.cs, that means something goes wrong when you call BuildSessionFactory().

I'd setting a breakpoint before that call, and see if you get to just before it but no further. As your tag is indicating you're using Fluent NHibernate, stepping through a fluent api doesn't work as well. You might want to chunk it up by doing repeated assignments of the FluentConfiguration to be able to step through it.

Perhaps you're not exposing the configuration correctly. Or perhaps you're using an InMemory SQLite database. In the latter case you will have to store the configuration in a variable and build the schema after you open the session. (Each InMemory session gets its own memory database.)

Finally the problem could be different versions loaded for different projects of yours. I recommend using NuGet, and managing your packages on the solution level as opposed to the project level, to avoid problems like that.

Finally, you might be using the wrong SQLite assembly. Are you running 32 or 64 bit?

So, that was a few shots in the dark. Hopefully they'll help you hunt down your bug though.
