One of packages I am using for my site is Auto mapper. A nifty little package that does save so much time to work with, if you use it correctly.
I do not understand all applications as yet, but I did grasp the basic.
While working with it I thought, is there a new version and after how much different it is.
Turns out, there was new version released and currently is:
<package id="AutoMapper" version="4.2.1" targetFramework="net451" />
to new one
<package id="AutoMapper" version="5.0.2" targetFramework="net451" />
The mapping syntax has changed, but the GitHub project repository did help.
So the syntax has changed for creating maps between classes
Mapper.Initialize(cfg => cfg.CreateMap<BusinessUser, ClientUser>());
