PW SDK using C#

Question

Hi all, 
 
 I am trying to develop something through the API of ProjectWise. I have been using ProjectWise since 2016 and ucrrently using PW 10.00.02.265. I have been reading through SDK manual since more than 2 weeks but I had no clue. I have been reading the below that thread ( https://communities.bentley.com/user/conversations#ConversationID=3def96ce-413d-4ac0-a799-46d0f2af79c6 ). which contains an image contining a sample login Dan Williams . 
 I feel that would be so helpful posting that sample which can save us a lot of time. 
 
 Regards,
