iserviceprovider autofac

With version 6, a single bus has a single host. Autofac 2. IOCDIPDI The previous interfaces are still supported, but have been marked obsolete. For example: public class UserProfile : Profile { private readonly IUserManager _userManager; public UserProfile(IUserManager userManager) { _userManager = userManager; CreateMap() To use scoped services (e.g. I can't figure out how to add Autofac into the middleware pipeline. We have placed an entire suite testing all the services to be injected, and it works like a charm. You can also use the .AddGraphTypes() builder method to scan the calling or specified assembly for classes that implement The OWIN integration had extensions like UseAutofacMiddleware() to allow DI into middleware. Site design / logo 2022 Stack Exchange Inc; user contributions licensed under CC BY-SA. Steven. setting up the per-request lifetime scope. For the most part, consumers, sagas, etc. // ConfigureServices is where you register dependencies and return an `IServiceProvider` implemented by `AutofacServiceProvider`. In ASP.NET Core 5 the following code works: Now if you change the IServiceScopeFactory to IServiceProvider it will NOT work: You will get the System.ObjectDisposedException exception: Which tells me the IServiceProvider will live as long as the request's lifetime (scoped), but this is not the case with IServiceScopeFactory. What's the difference between the Dependency Injection and Service Locator patterns? Now in this case if following scenario is there. Bypass invalid SSL certificate for Kestrel server displayed in WebView2. Inversion of Control vs Dependency Injection. The, // default ConfigureServices won't be automatically called if this, // Add things to the service collection that are only for the. You must choose one or the other, not both. You can inject an IServiceProvider into any class. Why are taxiway and runway centerline lights off center? Development of version 1.0 has started and is mainly braking changes regarding changes related to replacing EventFlow types with that of Microsoft extension abstractions, mainly IServiceProvider and ILogger<>. IServiceProvider is an interface with single method:. The IApplicationBuilder and HttpContext classes can provide the service provider as well, via their ApplicationServices or How can the electric and magnetic fields be non-zero in the absence of sources? Any help is greatly appreciated. But is there something like ServiceProvider.Current.GetService()? But here is a little difference between these abstractions. in .NET Core 3.1 using Autofac. Are witnesses allowed to give private testimonies? // you can override the controller registration after populating services. Consumers can now be connected/detached after the mediator has been created. Yes, this should be the default answer. // As with the first host, the second host will share the root container but have its own, // root lifetime scope `root-two`. Does the luminosity of a star have the form of a Planck curve? as usual. 3. (clarification of a documentary). But here is a little difference between these abstractions. When MassTransit underwent a major overhaul, and multiple host support was added, that seemed like a great idea. Therefore you will likely Find centralized, trusted content and collaborate around the technologies you use most. If the constructur also has dependencies that should be resolved by DI you can use that: Dependency Injection : ActivatorUtilities will inject any dependencies to your class. Connect and share knowledge within a single location that is structured and easy to search. It's changed since this post. in .NET Core 3.1 using Autofac 1 .NET 6 Serilog with Application Insights Instrumentation key not being picked up // Create a container-builder and register dependencies, // Populate the service-descriptors added to `IServiceCollection`, // BEFORE you add things to Autofac so that the Autofac, // registrations can override stuff in the `IServiceCollection`, // Register your own things directly with Autofac. All repositories also now support the container registration extensions, which provides a consistent syntax for registering and configuring saga repositories for use with dependency injection containers. public static IHostBuilder CreateHostBuilder(string[] args) => Host.CreateDefaultBuilder(args) .UseServiceProviderFactory(new AutofacServiceProviderFactory()) .ConfigureWebHostDefaults(webBuilder => { I was able to plug it in very easily. Finally, the GetServiceOrCreateInstance(IServiceProvider provider) method provides an easy way to provide a default instance of a type that might have been optionally registered in a different place. Standard Package Contributors. object GetService(Type serviceType); It's used to create instances of types registered in .NET Core native DI container. The lifecycle of controller constructor parameters is handled by the request lifetime. WebApplication properties expose the middleware configured by WebApplicationBuilder, eg WebApplication.Services exposes IServiceProvider. In your setup the UseIISIntegration "interferes" with UseUrls, as the UseUrls setting is for the Kestrel process and not the IISExpress/IIS. But after coding with this pattern for a while I start to think that the practicality of passing IServiceProvider deserves a second thought, for me, at least on job services (maybe not in rest apis). Connect and share knowledge within a single location that is structured and easy to search. While this list doesn't cover everything, these are the main items experienced so far when upgrading from a previous version. @SimpleFellow - I was thinking in the same line. Example var host = CreateWebHostBuilder(args).Build(); using (var scope = host.Services.CreateScope()) { var services = scope.ServiceProvider; var ds = services.GetService(); @CK - I had a similar scenario - needed async Background service. 'ConfigureServices returning an System.IServiceProvider isn't supported.' Internally when trying to resolve a type the library will call the methods on this interface. GraphQL.NET supports dependency injection through a IServiceProvider interface that is passed to the Schema class. 'ConfigureServices returning an System.IServiceProvider isn't supported.' 2 can be used to get a fast reference to a logger from ILoggerFactory. This example shows ASP.NET Core 1.1 - 2.2 usage, where you return an IServiceProvider from the ConfigureServices(IServiceCollection services) delegate. the scoped service provider into the ExecutionOptions.RequestServices property. 'ConfigureServices returning an System.IServiceProvider isn't supported.' But after coding with this pattern for a while I start to think that the practicality of passing IServiceProvider deserves a second thought, for me, at least on job services (maybe not in rest apis). Check out the job consumers section for details. When upgrading from previous versions of MassTransit, there are a few initial steps to get up and running. // In ASP.NET Core 3.x, using `Host.CreateDefaultBuilder` (as in the preceding Program.cs snippet) will, // set up some configuration for you based on your appsettings.json and environment variables. So, when we inject IServiceProvider into a controller for example, it is possible to resolve scoped dependencies without scope creating (because in this case scope is already created). How can I write this using less variables? I'm unsure what you mean with YAGNI in this context. An example test, shown below, using the in-memory transport by default. a nice example about how to replace Autofac with Microsoft.Extensions.DependencyInjection lnaie. No special middleware. you would need to use a serial execution strategy, or create a scope within each field resolver that 3IServiceProvider IServiceCollection BuildServiceProvider() IServiceProvider GetServices Transient Singleton In short, IServiceProvider.CreateScope() and IServiceScopeFactory.CreateScope() are identical (in non-scoped context even instances of IServiceProvider and IServiceScopeFactory are identical). Graph types will only be instantiated once, during schema initialization The example code below would return the configuration Default log level setting from the JSON configuration file. in .NET Core 3.1 using Autofac. Asking for help, clarification, or responding to other answers. Previously, each functionality - MVC, Web API, etc. MassTransit.Host is being replaced with the new Platform, which is a Docker-based solution for consistent service deployment using MassTransit. If the factory is asynchronous, and you use Task.Result, this will cause a deadlock. . rev2022.11.7.43011. // Don't build the container; that gets done for you by the factory. For reasons described above, it is recommended that the schema is registered as a singleton within The default one is working fine for me. Things registered `InstancePerMatchingLifetimeScope("root-two")`. Don't build or return // any IServiceProvider or the ConfigureContainer method // won't get called. This library (developed by me) (Xunit.Microsoft.DependencyInjection) supports .NET 6.0 and brings in Microsoft's dependency injection container to Xunit by leveraging Xunit's fixture. Registering things, // as `InstancePerMatchingLifetimeScope("root-one")` (the name of the scope given above). Configuring MassTransit using a container has been streamlined. Let's assume you have the default appSettings.json in place. AutoMapperMappingException when using ConstructUsingServiceLocator() in ASP.NET Core 2.1, Asp.Net Core HealthChecks Concurrent Entity Framework DbContext Errors. Entity Framework Core, typically the database context is registered as a scoped service and obtained via Refer to the configuration section for details. MassTransit would then be able to use IServiceProvider with Autofac to create scopes, resolve dependencies, etc. 'ConfigureServices returning an System.IServiceProvider isn't supported.' The basics are the same, only the configuration has changed. Standard Package Contributors. Aug 9, 2018 at 9:38. Entities should be as thin as possible. created for each operation, and context-relevant tags and baggage are added. The methods that were in Startup.cswere merged in Program.cs in .NET 6. Accurate way to calculate the impact of X hours of meetings a day on an individual's "deep thinking" time available? 1. // This is the MULTITENANT PART. Special wiring that you may have done during registration of the controller (like setting up property injection) wont work. Manager class: public class Manager : IManager { ILogger _logger; IFactory _factory; public Manager(IFactory factory, ILogger logger) { _logger = logger; _factory = factory; } } public static IHostBuilder CreateHostBuilder(string[] args) => Host.CreateDefaultBuilder(args) .UseServiceProviderFactory(new AutofacServiceProviderFactory()) .ConfigureWebHostDefaults(webBuilder => { package and utilize the SelfActivatingServiceProvider wrapper as follows: If you previously pulled in your query, mutation and/or subscription classes via dependency injection, you will need // will result in a singleton that's ONLY used by this first host. To what extent do crewmembers have privacy when cleaning themselves on Federation starships? In short, IServiceProvider.CreateScope() and IServiceScopeFactory.CreateScope() are identical (in non-scoped context even instances of IServiceProvider and IServiceScopeFactory are identical). The Configure, ConfigureServices, and ConfigureContainer methods all support environment-specific naming conventions based on the IHostingEnvironment.EnvironmentName in your app. I think the OP is getting confused. These tools have been updated to use a new technique to execute custom logic in the context of the app. Example with IServiceProvider gives error because serviceProvider that available in method using [FromServices] has lifetime of scope. There are overloads accepting a Func where T is the service being registered, and the parameter is named implementationFactory. if you need to manually do service location, get an IServiceProvider. This makes for a concise and declarative approach. Reference the Autofac.Extensions.DependencyInjection package from NuGet. Can humans hear Hilbert transform in audio? Provide a callback that will configure your tenants. Aug 9, 2018 at 9:38. This is not recommended; please see Scoped Services Most dependency injection frameworks allow for specifying different service lifetimes for different This is definitely in reference to ASP.NET 5. The transaction outbox has been renamed to TransactionalBus, to avoid confusion. 'ConfigureServices returning an System.IServiceProvider isn't supported.' MassTransit v8 is the first major release since the availability of .NET 6. ASP.NET Core uses the term service for any of the types property to resolve types via the scoped service provider. If you want to change the IIS Port, have a look at Properties/launchSettings.json - there you can configure the applicationUrl IIS is using. ASP.NET Core 5. @SimpleFellow - I was thinking in the same line. So, I registered my service as HostedService and then used injected IServiceProvider to GetRequiredService(). If the factory is asynchronous, and you use Task.Result, this will cause a deadlock. A single instance is created inside of the current HTTP Request scope. Why does sending via a UdpClient cause subsequent receiving to fail? // ConfigureServices is where you register dependencies. Additionally, the test harness can now be used with any transport. Specific .NET Framework packages are no longer built or packaged. Accurate way to calculate the impact of X hours of meetings a day on an individual's "deep thinking" time available? from a DI-provider-specific setup method (typically called AddGraphQL()), at which point you can call extension methods on the interface to To use SteroidsDI with ASP.NET Core, add Defer<> and IScopeProvider in your Startup.ConfigureServices: Then in your query graph types you can request services using Defer to be injected via DI, You have to bring in Microsoft.Extensions.DependencyInjection namespace to gain access to the generic. of how it is registered with the DI framework. See list below: Microsoft.Extensions.DependencyInjection package used in ASP.NET Core already has support for resolving IServiceProvider interface so no additional settings are required - just add your required dependencies: To avoid having to register all of the individual graph types in your project, you can Why am I being blocked from installing Windows 11 2022H2 because of printer driver compatibility, even with no printers installed? I was able to plug it in very easily. Register your "root". Making statements based on opinion; back them up with references or personal experience. services. In this scenario. Don't forget if your service takes other parameters you have registered, you can pass a reference to your service when it is registered. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Generally you want to have the DI do its thing and inject that for you: However, Entity would have to be automatically instantiated for you like a Controller or a ViewComponent. If you want to change the IIS Port, have a look at Properties/launchSettings.json - there you can configure the applicationUrl IIS is using. With Microsoft.Extensions.DependencyInjection and the Startup.ConfigureServices method, you now just return the IServiceProvider and magic happens. Within controllers, classes, etc. Finally, the GetServiceOrCreateInstance(IServiceProvider provider) method provides an easy way to provide a default instance of a type that might have been optionally registered in a different place. The IApplicationBuilder and HttpContext classes can provide the service provider as well, via their ApplicationServices or In fact, it is really hard. To continue to use the database context in the same manner with a singleton schema, Here are some helpful links into the ASP.NET Core documentation with specific insight into DI integration: ASP.NET Core dependency injection fundamentals, The Subtle Perils of Controller Dependency Injection in ASP.NET Core MVC, Authorization requirement handlers injection. Is it enough to verify the hash to ensure file is virus free? AutofacChildLifetimeScopeServiceProviderFactory, // create the root-container and register global dependencies, // Each host listens to a different URL, they have the same root container to share SingleInstance, // things, but they each have their own logical root lifetime scope. Getting started Nuget package. Object deserialization fails POST in These two things are combined in ASP.NET Core so theres only one dependency resolver to set up, only one configuration to maintain. With scoped schemas, it is required that all its graph types are registered within the DI // here if you need to resolve things from the container. The IServiceCollection interface is used for building a dependency injection container. Using a child lifetime scope as the root is not compatible with multitenant support. To learn more, see our tips on writing great answers. 'ConfigureServices returning an System.IServiceProvider isn't supported.' AutofacChildLifetimeScopeConfigurationAdapter, // IHostingEnvironment when running applications below ASP.NET Core 3.0. Object deserialization fails POST in @onefootswill Since there is no limit to how many services scopes can exist at the same time, how would the root IServiceProvider be able to tell which service scope to use in your arbitrary singleton (which is scope-independent by design)? This is a perfect example of "how many ways NOT to do dependency injection". Adding a specific NPM package resource (js, css files) into a bundle is pretty straight forward for that package. Double check that your client isn't looking at a scope that isn't configured in your ApiScopes configuration. ASP.NET Core 5. ASP.NET Core uses the term service for any of the types Another approach to resolve scoped services is to use the SteroidsDI project, as described below. Code snippet from Autofac website. System.NullReferenceException at Startup.ConfigureServices(IServiceCollection services) in windows server. The .NET Core integration documentation also shows an example of using a child lifetime scope as a root. No more calling GetPayload or other methods to get access to the ConsumeContext! These tools have been updated to use a new technique to execute custom logic in the context of the app. This means that every aspect of MassTransit is now within a single namespace, which makes it easy to find the right interface, extension, and whatever else is needed. With ASP.NET Core 3.1, and all the goodness that is the generic host, the developer community has moved to a new place. I believe the exercise that @Sam is referencing comes from the following: Its ok for constructor injection, but how about EF, do they inject objects while materializing from database ? For instance, calling UseMemoryCache prior to UseAutomaticPersistedQueries would result in A new version of the test harness is now available, specifically designed for use with containers. // ConfigureContainer is where you can register things directly, // with Autofac. The default one is working fine for me. IDisposable will be disposed of properly, regardless of whether the graph type is registered within the service provider. Good article on a subject: .NET Core IServiceScopeFactory.CreateScope() vs IServiceProvider.CreateScope() extension, learn.microsoft.com/en-us/dotnet/architecture/microservices/, Stop requiring only one assertion per unit test: Multiple assertions are fine, Going from engineer to entrepreneur takes more than just good code (Ep. The methods that were in Startup.cswere merged in Program.cs in .NET 6. Do FTDI serial port chips use a soft UART, or a hardware UART? See the transactions section for details. This means you dont necessarily have to use Autofac configuration to switch configuration between a development and production environment; you can set it up programmatically in Startup. For example for Autofac: You can either provide a delegate to manually instantiate your cache provider or directly provide an instance: Please note that the container will not explicitly dispose of manually instantiated types, even if they implement IDisposable. , The_consumer_should_respond_to_the_request, MassTransit.Extensions.DependencyInjection. 'ConfigureServices returning an System.IServiceProvider isn't supported.' Why are UK Prime Ministers educated at Oxford, not Cambridge? GraphQL.NET provides an IGraphQLBuilder interface which encapsulates the configuration methods of a dependency injection framework, to provide an Manager class: public class Manager : IManager { ILogger _logger; IFactory _factory; public Manager(IFactory factory, ILogger logger) { _logger = logger; _factory = factory; } } To subscribe to this RSS feed, copy and paste this URL into your RSS reader. HttpContext scoped services in ASP.NET Core) you will need to pass Thanks for contributing an answer to Stack Overflow! Manager class: public class Manager : IManager { ILogger _logger; IFactory _factory; public Manager(IFactory factory, ILogger logger) { _logger = logger; _factory = factory; } } In previous ASP.NET integration you could register a dependency as InstancePerRequest which would ensure only one instance of the dependency would be created per HTTP request. When the provider (which is an IServiceProvider) is disposed, it will dispose of the test harness, which will stop the bus.
