Test project on how to combine object expressions
Code for my StackOverFlowQuestion on how to combine two Expressions of object func :-)
I also filed an issue at Atomapper that prompted the SO question.
The reason I was doing this was to control what related data was loaded in my RazorPage (web layer) and getting that information down through my ServiceLayer to the RepositoryLayer where my Entity Framework is.
This then "Expression chaining" looks promising.
