[uttamughareja]

Automapper is going commercial

Pricing model is not yet finalized, More details can be found here.

Possible High Performance Alternatives
Mapster:

Mapperly:

Also we can consider making a fork of Automapper until its license is changed

Or simple extension methods with handwritten code.
