问题 I have a manager class that loads various plug-in modules contained in separate assemblies through reflection. This modules are communication to the outside world (WebAPI, various other web protocols). public class Manager { public ILogger Logger; // Modules need to access this. private void LoadAssemblies() { // Load assemblies through reflection. } } These plug-in modules must communicate with an object contained within the manager class. How can I implement this? I thought about using

问题 I just pasted the 4 lines at the end from another project and it works but I get a warning.. I clearly do not understand DI well enough ... What does it want me to change ? public void ConfigureServices(IServiceCollection services) { if (HostingEnvironment.EnvironmentName == "Local") { services.AddHealthChecksUI() .AddHealthChecks() .AddCheck<TestWebApiControllerHealthCheck>("HomePageHealthCheck") .AddCheck<DatabaseHealthCheck>("DatabaseHealthCheck"); } services.Configure<PwdrsSettings>

问题 I am currently facing a very interesting dilemma with my architecture and implementation. I have an interface called ServiceInterface which have a method called execute() Then I have two different implementations for this interface: Service1 and Service2 , which implements the execute method properly. I have a controller called MainController and this controller has a "type-hint" for the ServiceInterface ( dependency injection ), it means that both, Service1 and Service2 , can be called as

问题 When I register multiple services to the DI container with the same interface and then request an IEnumerable<IService> , do the container guarantee that the order of registration will be the order of the collection? because this seems to be the behavior but I couldn't find anything about it in the documentation. Example - let's say we have this interface: public interface IStep { void Execute(); } And some implementations: public class FirstStep : IStep { ... } public class SecondStep :

问题 Want to write unit test for HttpTrigger GET. Have method signature as follow: public static async Task<HttpResponseMessage> Run( [HttpTrigger(AuthorizationLevel.Function, "get", Route = null)] HttpRequestMessage request, ILogger log) here, ILogger is type of Microsoft.Extensions.Logging. How to write unit test case with this injection, Tried to create stub of ILogger using below stuff but this needs LoggerFactory . public class LoggerWriter : Microsoft.Extensions.Logging.Logger<ILogger> {
