Question:
I saw the generated code references two dll's. Is the source code available for these libraries, because my customers require me to be able to access that sourcecode ?
Solution:
Yes, a customer can download the sourcecode for these two libraries from the customer area at no extra charge. The source code for these libraries is also included in the LLBLGen Pro installer (not in the demo). We believe customers shouldn't pay extra for the access right to that source code. The source code is in C#.
