问题 In my backend service I use unit of work pattern. I was wondering if I'm missing something related to disposing objects. First, this is the code I have so far, which works. The service just calls a request handler: [GlobalExceptionHandlerBehaviour(typeof(GlobalExceptionHandler))] public class CustomerService : ICustomerService { public void AddCustomer(AddCustomerRequest request) { ObjectFactory.GetInstance<AddCustomerRequestHandler>().Execute(request); } } The request handler looks like:

问题 I want do a binding like this, bind(Supplier<TestClass>).toProvider(Provider<Supplier<TestClass>>).in(Singleton.class); The provider is returned by an external function so, inside the toProvider() , I call that function and it returns Provider <Supplier<TestClass>> . The supplier is from guava, the reason to do this kind of thing is, there is a file associated with the TestClass and I need to read that file and assign those values to the respective fields of TestClass.

问题 The application I'm trying to get to work uses MVVM. The biggest part of this post is an explanation of what I tried and what I got working. The question is near the bottom of the post.

This purpose of this class is to change the language of the application on the fly, without having to restart the application. The `Localizer has to be

问题 We have a multitenant architecture with more than one user like below with identity core library: public class ApplicationUser : IdentityUser { } public class Tenant1User: ApplicationUser { public int deneme { get; set; } } public class Tenant2User: ApplicationUser { public string City { get; set; } public string Picture { get; set; } public DateTime? BirthDay { get; set; } public int Gender { get; set; } } We wanted to use UserManager generically in controllers constructors when injecting

问题 In an app running Framework 4.72, not .NET Core, I'm trying to inject a SignalR IHubContext into a Web API 2.x service. I have my solution broken into three projects, web, service, data. The SignalR hub is in the web layer. I have background code that runs in the service layer and when complete I need it to send a mesage via the hub. This background task is not initiated by the controller. My Global.asax is pretty standard: protected void Application_Start() { GlobalConfiguration.Configure

问题 Background: I need to perform couple of initial checks during the application start up (1) read angular app config from ./assets/config.json file and get the API end point from there, (2) make an API call to end point retrieved in first step and load some settings from back end. Goal: be able to initialize two services using APP_INITIALIZER (say A & B), where B has a dependency on A. check out this stackblitz to see the problem Things I've tried: If second part (being able to make an API

问题 I have a class that requires ApplicationUser (from ASP.NET Identity). The instance should be the current user. public class SomeClass { public SomeClass(ApplicationUser user) { Currently, what I'm doing is I inject the current user from the Controller: var currentUser = await _userManager.GetUserAsync(User); var instance = new SomeClass(currentUser); Now I want to use Dependency Injection provided by Microsoft. I can't figure out how am I going to add ApplicationUser to the services. It
