I'm trying to get phxsoftware's System.Data.SQLite managed-only dll  
working under mono. The readme claims i should just need the binary in  
the same directory and it works for mono. It does work for windows, i  
just drop sqlite3.dll in the dir and it works. However, i try the same  
with sqlite3.so and i get the following on opening the connection:

Unhandled Exception: System.EntryPointNotFoundException:  
   at (wrapper managed-to-native)  
System.Data.SQLite.UnsafeNativeMethods:sqlite3_next_stmt (intptr,intptr)
   at System.Data.SQLite.SQLiteBase.ResetConnection  
(System.Data.SQLite.SQLiteConnectionHandle db) [0x00000]
   at System.Data.SQLite.SQLiteBase.CloseConnection

   at System.Data.SQLite.SQLiteConnectionHandle.ReleaseHandle ()  
   at System.Runtime.InteropServices.CriticalHandle.Dispose (Boolean  
disposing) [0x00000]
   at System.Runtime.InteropServices.CriticalHandle.Dispose () [0x00000]
   at System.Data.SQLite.SQLite3.Close () [0x00000]
   at System.Data.SQLite.SQLiteConnection.Close () [0x00000]
   at System.Data.SQLite.SQLiteConnection.Open () [0x00000]
   at SqliteMixedTest.Program.Main (System.String[ args) [0x00000]

Same result if i try to rename to .so to .dll or use <dllmap> in the  
config. True whether i use the binary for sqlite-3.8.14 or build it  
from source. I tried this a while back with mono 1.9.1 and now i'm  
trying it with 2.4. Any suggestions?

The reason i'm not using Mono.Data.Sqlite is that i do my dev and  
initial unit testing in Visual Studio and am using fluent nhibernate  
(built against System.Data.Sqlite) and then deploy to linux. If there  
is a way to get this scenario working with Mono.Data.Sqlite, i'm open  
to that option as well.
