There are a few threads on this forum about obfuscation how to's. I came across an 'affordable' piece of protection software recently which I purchased called .NET Reactor, in preference to the over the $1500 plus tools that are out there.

Anyone have any experience of this. My experience is that code that woks in VS.NET 2003 debug and release versions throws a few exceptions when I run a protected version.

Here's a simple scenarion: a booking entity with a single attached passenger (travel domain speak), code that works perfectly OK unprotected, create a booking entity and attach a passenger entity.

Anyone of you knowledgeable guys have any idea. Anyone tried .NET Reactor with LLBLGen, interested to know.

************** Exception Text ************** SD.LLBLGen.Pro.ORMSupportClasses.ORMQueryExecutionException: An exception was caught during the execution of an action query: Cannot insert the value NULL into column 'Booking_ID', table 'Yatra_MidOffice.dbo.Passenger'; column does not allow nulls. INSERT fails. The statement has been terminated..

Exception seems unrelated to protected version. Please examine the generated query and try to run it manually against the database.

I get the same error with a simple bit of test code. I'll send these guys a bit of test code I think and see what their response is.

public bool SaveTestBooking() { BookingEntity booking = new BookingEntity(); booking.AppUser_ID = 2;; booking.CreationDate = DateTime.Now; booking.Client_ID = 1; booking.BookingSourceCode_ID = 3; booking.WebSiitBookingReferfence = "A1B2C3D4"; booking.BookingStatus_ID = 1;

PassengerEntity pax = new PassengerEntity();
pax.PassengerType_ID = 1;
pax.PassengerTitle_ID = 1;
pax.Initials_Forename = "C";
pax.Surname = "Test";
pax.LeadPassenger = true;
// assign pax to booking
booking.Passenger.Add( pax );

DataAccessAdapter adapter = new DataAccessAdapter();
bool IsSaved = adapter.SaveEntity( booking, true );

return IsSaved;

}

Just to be clear: when you don't obfuscate the code, it does work?

Also tried the dotfuscator community edition shipped with vs.net?

Yes that's right: unobfuscated code works fine, protected code not.

I really wanted to know if anyone else has used this .NET Reactor product. I didn't want to pay $1500 for obfuscation software, and at $175 this product seemed worth a go. My view of buying software is that there is decent software out there that is sensibly priced, e.g., LLBLGen, Sparx Enterprise Architect. As well as protection it also has a licensing system

Rather than me mailing their support with a sample app would you be interested in taking a look at .NET Reactor, maybe taking a sample app to see what results you get. If you can reproduce the same problem then I'll certainly follow up with their support team.

Did you use necrobit protection?
