In October 2015, I got an opportunity as an intern in TreeSoft Consultancy & Software. The POS was already developed by Mr. Shoman Gurung who is the co-founder and system analyst there.
But the problem was “it was developed using VB6, an obsolete language” so if updates were to be implemented in the software, it would be a waste (i think) because it was in VB6, an old language where its community werenot bigger too. So, the intention was that it would be best to rebuilt and update the features of the system using C#.NET (a new modern language having great community to support) rather than updating the using VB6. So, we developed the software by working together in Windows Form template in VS 2012. Here, i learned about the Crystal Report for the first time and it was cool.
