When I am trying to start serializable transaction:
using (var trans = _context.Database.BeginTransaction(IsolationLevel.Serializable)

I am getting exception: Object reference not set to an instance of an object.
with stacktrace:

EF.Firebird 4.10.0.0
EF 6.1.3

The exception doesn't occure while I execute the same code in Console Application.

I think it is quite serious issue while there is no possibility to start serializable transaction with firebird provider.
Is it intended to resolve it ?
