Change some struct/value types to class/reference type

[cmoha]

Dear Eng Ehsan,
Is it possible to change the type of some data types such as LoadType, Settlement, etc.. to be reference type.
This will be very handy in WPF applications and will make databinding works.

Hi,
Did used struct for those types only because they are sort of primitive types (like int, double, etc.).
Most common structures are Force, Displacement, BendingStressTensor, CauchyStressTensor, Constraint, LoadCase, Settlement, StrainTensor, Vector, Point and IsoPoint. Which ones do you suggest to convert into class?

[cmoha]

I suggest Force, Displacement, Constraint, LoadCase and Settlement.
Because These types are more likely to be in an interaction with a gui.

Let me think about it, not sure it meet the conditions of class instead of struct

also take a look at here:
https://docs.microsoft.com/en-us/dotnet/standard/design-guidelines/choosing-between-class-and-struct

Except for second condition, all other conditions are met

Also about using with WPF, i think this library better to be not used directly with WPF. I mean ideally it is better to create the a data model for your project yourself, and that model only use this library for calculations etc. For example a building which have elevations, grids etc can be custom data model, then that model creates a Finite Element model as instance of Model class with a method like CustomBuilding.GenerateFEModel()

I understand your point. But I want to use these types directly instead of creating and copying classes then at linking time, there will a conversion between the project and bfe library.
