About QuestPond: It started 15 years back with the one single goal of creating quality step-by-step IT programming-related lessons.
We saw many lessons online, either they are done too fast or too slow or are too complicated.
The main goal of QuestPond is to create Step by Step lessons on C#, ASP.NET, Design patterns, SQL, and so on. As years moved on I added other step-by-step lessons like Angular, SharePoint, MSBI, Azure and so on.
