Came across this problem today which had me going around in circles for quite a while.
I was working through the example on the Fluent Nhibernate website. Got all the code typed in but I kept on getting the following error when I tried to run the code. :
InnerException: NHibernate.HibernateException Message="Could not create the driver from NHibernate.Driver.SQLite20Driver, NHibernate, Version=126.96.36.19900, Culture=neutral, PublicKeyToken=aa95f207798dfdb4." ..... The IDbCommand and IDbConnection implementation in the assembly System.Data.SQLite could not be found
I looked at the GAC, removed the SQLite dlls and made sure I was referencing the right dll and was copying local. Read about referencing Log4Net dlls etc. tried that but that didn’t work. Tried explicitly compiling 32bit as I’d seen quite a few posts linking this with problems too. None of these worked for me.
Eventually got a hold of an older version of the dll, v1.0.60 from here, replaced 1.0.65 with 1.0.60 and it worked straight away. Might be worth a go if you’re having the same problem.
I’ll see if I can shed any more light on the problem but might fire an Email off to Nhibernate to see if they’re aware of any issues.
