DLL(Assembly) Reference or Layer in API Project

Hello there,

I have 2 question pertaining to the same query. Project is API with REPO

Our project has multiple features like BusinessInsurance, VehicleInsurance, FleetInsurance etc about 40 such features approx having kept underEntities/Business layers. Now we are in the start of our application. As we have so many features, the API solution may be problem if we have change in future. I m thinking to make all these features in a DLL assembly and then reference in my respective entities or business layer and use it. Please let me know if this is a feasible solution

Secondly - If I make this as DLL - then how would I make Version update automatic or kind of less work in our main API application. Like <bindingRedirectoldVersion="1.0.0"newVersion="1.0.1" /> does this way work ?

Thanks
