I have to agree here, when I was working in C# and in the Microsoft stack it is pretty nice. But I still remember it had some tedious tasks around data mapping etc. C# was one place were I did use an ORM I liked, specifically dapper, it wasn't perfect, but damn it was fast and easy to use.

Looks interesting, thank you. Have you used it yourself? If so how do you deal with queries like: 'my' private messages from a single user.
