  • v6.1.0 Changes

    December 04, 2020
    • βž• Added direct support for .NET 5.
    • ⚑️ Internals update to allow more dynamic reconfiguration of resolve pipelines.
    • πŸ›  Fix #1204: Decorated instances marked with AllowCircularDependencies should now get properties injected correctly.
    • πŸ›  Fix #1226: Constructor binders correctly detect ref parameters.
  • v6.0.0 Changes

    September 28, 2020

    πŸ”– Version 6.0.0 represents a major update in the Autofac internals. While every effort has been made to ensure code using version 5.x will continue to work exactly as you expect, you should be aware of the breaking changes and test things out. For the majority case, things should just continue to work; breaking changes are primarily in more rare advanced usage scenarios.

    πŸ“š Check out the release blog post! Also, the documentation has been updated and is ready!

    🚚 > ⚠️ Starting with Autofac 6.0, we now only target netstandard20 and netstandard21; we have removed the explicit target for net461.

    πŸ“š > The impact to you is that, while Autofac will still work on .NET Framework 4.6.1 as it did before, we strongly encourage you to upgrade to .NET Framework 4.7.2 or higher, as per the .NET Standard Documentation, to avoid any of the known dependency issues when using .NET Standard packages in .NET Framework 4.6.1.

    πŸ†• New Features

    πŸ›  There are a lot of new features, but the big ones are here. Other features and fixes will be outlined in the Issues section, below.

    Issues and PRs

    The following issues have been addressed in v6:

    • πŸ‘ #718: Circular dependency support using property injection and relationships like Lazy<T> should now work.
    • πŸ“¦ #788: DOT graph support has been added via the Autofac.Diagnostics.DotGraph package.
    • πŸ›  #798 / #1148: Circular dependency handling uses the .NET runtime to check stack depth when checking for circular dependencies rather than using a fixed stack depth.
    • #828: The ILifetimeScope.LifetimeScopeEnding event is raised and completes before the scope is disposed.
    • πŸ‘ #970: The composite pattern is now supported.
    • #1069 / #1172: Core Autofac events are now async-friendly.
    • #1120 / #1128: ContainerBuilder is now sealed.
    • #1123: Explicitly injected properties can now be declared using an expression.
    • #1126 / #1169: Diagnostics are handled via DiagnosticSource.
    • πŸ“¦ #1162: A new "pooled" lifetime type has been added via the Autofac.Pooling package.

    πŸ’₯ Breaking Changes

    πŸ“š We'll do our best to keep an upgrade guide with breaking changes available and up to date. We're pretty sure we caught them all, but if you find a gotcha, let us know on the Documentation repo.

    A summary of the breaking changes is as follows:

    • net461 is no longer targeted ; Autofac now targets netstandard2.0 and netstandard2.1.
    • Activation events are no longer exposed - this all happens through middleware now.
      • If you were using an Autofac module to attach to activation events and inject parameters, similar to the way the log4net module example is shown in the document, this now needs to happen through middleware. The log4net module example has been updated to show you the new way it works.
      • RegistrationBuilder.RegistrationData no longer exposes activation handlers. The CoreEventMiddleware is the source of events now.
      • IComponentRegistration no longer exposes activation events. The CoreEventMiddleware is the source of events now.
    • Interface changes :
      • IConstructorSelector implementations need to switch to use BoundConstructor instead of ConstructorParameterBinding.
      • IRegistrationSource implementations need to update the RegistrationsFor method signature.
      • IInstanceActivator implementations no longer have an ActivateInstance method and instead have a ConfigurePipeline method.
      • IComponentRegistry no longer supplies a DecoratorsFor method to check decorators. Use IComponentRegistry.ServiceMiddlewareFor instead.
      • The ResolveRequest constructor now takes a ServiceRegistration instead of an IComponentRegistration.
    • ContainerBuilder is now sealed.

    Still Todo

    πŸ“¦ We're working hard to get all of the ~25 integration packages pushed to NuGet as quickly as we can, so please bear with us while we get these sorted.

    πŸ“¦ Some of this is sitting in branches ready to go, other things need to be done now that we have this core package out there.

    If your favorite integration isn’t ready yet, we’re doing our best. Rather than filing "When will this be ready?" issues, consider pull requests with the required updates.

  • v5.0.0 Changes

    January 27, 2020

    This is the first major-version release we've had in about three years (Autofac 4.0 was released in August 2016). There are some breaking changes and new features you should know about as you decide your upgrade strategy.

    πŸ’₯ Breaking Changes

    Framework Version Targeting Changes

    πŸ‘ Starting with Autofac 5.0 there is no longer support for .NET 4.5.x. .NET 4.5.2, the last release in that line, follows the same support lifecycle as Windows Server 2012 R2 which ended mainstream support in September 2018.

    Autofac 5.0 now targets:

    • netstandard2.0
    • netstandard2.1
    • net461

    Containers are Immutable

    ⚑️ The container registry can no longer be updated after it has been built.

    ⚑️ The ContainerBuilder.Update method was marked obsolete in November 2016 and there has been a robust discussion to answer questions about how to get the container contents to adjust as needed at runtime.

    ⚑️ ContainerBuilder.Update has now been removed entirely.

    πŸ“š If you need to change registration behavior at runtime, there are several options available to you including the use of lambdas or child lifetime scopes. See this discussion issue for examples and ideas. We will work to add some documentation based on this issue.

    [PR #948 - thanks @weelink!]

    Lifetime Scope Disposal Hierarchy Enforced

    Resolving a service from a lifetime scope will now check all parent scopes to make sure none of them have been disposed.

    If you dispose a lifetime scope, all children of that lifetime scope will stop resolving objects. In cases like this you'll start getting ObjectDisposedException instead.

    βœ… If you have a custom application integration that involves creating/destroying lifetime scopes (e.g., custom per-request support) this may cause issues where proper disposal ordering is not occurring.

    πŸ›  [Fixes #1020; PR #1061 - thanks @alistairjevans!]

    Prevent Auto-Injecting onto Static Properties

    Autofac will no longer do property injection on static properties when auto-wiring of properties is enabled.

    πŸ— If your application behavior depends on static property injection you will need to do some additional work like adding a build callback to populate the property.

    πŸ›  [Fixes #1013; PR #1021 - thanks @alistairjevans!]

    πŸ”‹ Features and Fixes

    πŸ‘ Asynchronous Disposal Support

    Autofac lifetime scopes now implement the IAsyncDisposable interface so they can be disposed asynchyronously.

    await using (var scope = container.BeginLifetimeScope()) { var service = scope.Resolve\<ServiceThatImplementsIAsyncDisposable\>(); // When the scope disposes, any services that implement IAsyncDisposable will be// Disposed of using DisposeAsync rather than Dispose.}
    

    [PR #1037 - thanks @alistairjevans!]

    Nullable Reference Type Annotations

    πŸ— Autofac is now build using nullable reference type annotations. This allows developers to get sensible compiler warnings if they opt-in, thus avoiding NullReferenceException instances where possible.

    ⚠ Nullable reference type warnings

    [PR #1037 - thanks @alistairjevans!]

    πŸ— Build Callbacks in Lifetime Scopes

    πŸ— One method of running code at container build time is by registering a build callback. Previously this only worked at the container level, but we've added the ability to register callbacks that run at lifetime scope creation as well.

    var scope = container.BeginLifetimeScope(cfg =\>{ cfg.RegisterBuildCallback(scope =\> { /\* do something \*/ }); });
    

    The callback will be invoked just prior to BeginLifetimeScope exiting, after any startable components are instantiated.

    πŸ›  [Fixes #985; PR #1054 - thanks @alistairjevans!]

    πŸ›  Other Fixes

    Still TODO

    Now that Autofac 5.0 is out, there is still a lot to do. We'll be working on these things as fast as we can:

    • ⚑️ Updating integration packages we support so they ensure compatibility with Autofac 5.
    • πŸ“š Updating the documentation to reflect the above changes.

    πŸ“¦ Some of this is sitting in branches ready to go, other things need to be done now that we have this core package out there.

    If your favorite integration isn't ready yet, we're doing our best. Rather than filing "When will this be ready?" issues, consider pull requests with the required updates.
