||For those who don’t know what MVPs Open Day is
Every year Microsoft MVP Award Program organizes an event dedicated for MVPs only. In such event MVPs gathered together from different cities (South Asia MVP region includes India, Nepal, Bangladesh etc countries). Such events feature technical sessions designed to enhance the community's understanding of new Microsoft products, existing tools and new techniques. But MVPs like me don't come to learn just from Microsoft teams, we present during Open Days, which allows MVPs to    i) share real-world knowledge of Microsoft technologies aka "MVP to MVP" sessions    ii) network with fellow MVPs in person and this helps understand community more closely    iii) enjoy with fellow MVPs

I had a great time with MVPs and Lead. I would like to thank Biplab and Gandharv for organizing this event beautifully.
