Hi,
I'm getting in this error:
Running Seed method. System.Exception: Error Seeding DbSet<Itix.Opme.Domain.Model.Procedimento>: System.ArgumentNullException: Value cannot be null. Parameter name: stream at System.IO.StreamReader..ctor(Stream stream, Encoding encoding, Boolean detectEncodingFromByteOrderMarks, Int32 bufferSize, Boolean leaveOpen) at System.IO.StreamReader..ctor(Stream stream) at EntityFramework.Seeder.Seeder.SeedFromStream[T](IDbSet1 dbSet, Stream stream, Expression1 identifierExpression, CsvColumnMapping1[] additionalMapping) ---> System.ArgumentNullException: Value cannot be null.

That's because it's not able to load the file. Please check how you attach the file - please check the attachment from this sample project https://github.com/dpaquette/SeedingDatabaseFromCSV. Yes this is a hell ambiguous message and you can waste days on this. Hope this helps.

In most cases, I haven't been able to get proper error messages to report through to the Package Manager Console. This might be one of those areas where I can actually display a better message
