I took a look at Stack Overflow Stack-Exchange Data Explorer that is built in MVC and is open-source application to query the Stack Exchange data dump that is being provided by Stack Exchange team in every month or few. I do have a dump, but I was more curious to know about the application that they built to query the database. And I must admit that I learned tons of things. I came to know the power of Micro-ORM (Dapper) over Entity-Framework (EF) and one more pretty thing that attracted me was the routing mechanism used in the application. I strongly recommend that you check out this tool/application and take a deep dive in the code, lot of things to learn.
