We just upgraded from 2.5 to 2.6 and found that all of the DefineField() methods from ResultSetFields are not generated.

I found this thread which indicates the signature of the method has changed in 2.6:

However, these DefineField() methods do not exist at all.

Apologies if this is an obvious issue but I have not found anything about it in the forum or FAQs. How can we get back the DefineField() methods?

These DefineField method overloads are there. Please make sure you are referencing the correct LLBLGenPro v2.6 assemblies in your projects.

OK, they're in the runtime libs and not generated code? That would make sense.

Thanks!

Yep. ResulsetFields is part of ORMSupportClasses that is in SD.LLBLGen.Pro.ORMSupportClasses assembly, so you should double check that you are using the correct (v2.6) assembly
