Can anybody please help to resolve this issue..
I tried saveral things after googling but yet no luck…

This error occurs while running fixtures in my project.

NHibernate.HibernateException : Could not create the driver from
NHibernate.Driver.SQLite20Driver.
System.Reflection.TargetInvocationException : Exception has been
thrown by the target of an invocation. System.ArgumentException :
Unable to find the requested .Net Framework Data Provider. It may not
be installed

Here is the stack trace

I tried to resolve it by changing the test settings and loading required sql lite package via package manager console.
I am running 64Bit system. Can any body help me to figure out what could be the issue?

Please help,
Thanks

Answer 1

Is the native SqLite dll in compile path or in global assembly cache?

Do you have a 64bit version of the native SqLite.dll (SqLite dll contains unmanaged code and must have the same (64/32) as you project build).

If you force your project build to 32-bit does it work then?
