问题 OK, I am getting the familiar error: An error occurred when trying to create a controller of type 'UserController'. Make sure that the controller has a parameterless public constructor. ---> System.ArgumentException: Type 'Project.WebApi.Controllers.UserController' does not have a default constructor at System.Linq.Expressions.Expression.New(Type type) I am building a WebApi2 project (no MVC front end) that use Onion Architecture, putting most of my start-up code in App_Start of a Bootstrap

问题 I am planning to follow onion architecture for my new application. the solution hierarchy is as follows Domain - where all the interfaces for the services and repositories defined. Infrastructure - this is the layer where all data access is placed. these classes typically implements interfaces defined in domain. Web - this is my presentation part of the application. inside the same layer i have separate for folder for implementing the services defined in domain. My plain is to use Dependency

Is the StaticFactory<T> in codecampserver a well known pattern?

由 妖精的绣舞 提交于 2019-12-10 18:01:43
问题 CodeCampServer source code contains a generic StaticFactory. I'm surmising that this is a key piece of the mechanism for how the framework plays well with Dependency Injection. Subclasses of which use it's DefaultUnconfiguredState to provide static access to, well, a Default Unconfigured State for themselves which the dependency resolution mechanism can replace with working stuff. I've not been able to find any documentation for this... Is there a good explanation in the book? (I'm awaiting

In an Onion type architecture, should the entities cross the outer layer?

由 假如想象 提交于 2019-12-10 11:43:17
问题 I've been trying to understand this new kind of architecture which names can be Onion architecture, Clean architecture, Ports and Adapters, etc. If I take the abstraction of Ports and Adapters, when I adapt my application for a particular port, is it ok for me to give the port an entity from inside my application? Or am I always supposed to adapt the entities also, to fit the port? Example: Say I have a Customer entity. I have a UI that uses my application. My UI calls through an Adapter to

Setting the identity of a Domain Entity

问题 All entities in the domain need to have identity. By inheriting from DomainEntity , I am able to provide identity to classes. City domain entity (stripped down for easy reading): public class City : DomainEntity, IAggregateRoot { public string Name { get; private set; } public Coordinate Coordinate { get; private set; } public City(string name, decimal latitude, decimal longitude) { Name = name; SetLocation(latitude, longitude); } public City(string name, decimal latitude, decimal longitude,

EF6 and Onion architecture - database first and without Repository pattern

由 烂漫一生 提交于 2019-12-06 14:53:02
问题 I'm trying to put it all together for an new architecture for existing application. Existing application has a lot of business logic, so I thought that Onion architecture (or something like that - layered, decoupled) could be the right solution - http://jeffreypalermo.com/blog/the-onion-architecture-part-1/ All examples that I have seen use Repo/UoW (on top or ORM) pattern in Infrastructure layer (or DAL, or whatever the layer that actually connects to database is called). But I'm not sure

问题 I started to work with .net core and Entityframework 7 in Onion Architecture ! i readed this tutorial and i think its best case for learning following subject. but one part of this tutorial made a big question inside my brain. like what you see at this linked page; at Data Layer we have some classes which are our model!! public class User : BaseEntity { public string UserName { get; set; } public string Email { get; set; } public string Password { get; set; } public virtual UserProfile
