Hello ...
I have a question, I want to make a multiplatform application, layered, how many layers can be used?
I validations layer, business logic and data access when I'm in the layer of validations such an event clicked (public async void btnApply) ... of there way to the business logic layer to access data after when I'm in this layer and returned me an exception ... but if I step layer to access data validations me works perfect.
