Welcome, and thanks for your interest in this small library!

After years of developing data applications using C# and relational databases I ran into the same issues over and over again:

• Attaching entities coming from web request to the DbContext
• Performing partial updates, given that there is no undefined value in C#.
• Auto mapping tons of DTOs

Tried different solutions such as:

• GraphDiff which is great but doesn't work for .NET Core and it's performance can be improved
• AutoMapper that doesn't handle ORMs very well and after version 9.0 where all mappings has to be defined before being used which trimmed most of my ideas.

After that I decided to get the best of those tools and try to put them togheter in a library that maps any DTO directly to already attached entities. And this is the result, hope it works for your project!
