Full Changelog: v8.0.0...v9.0.0

v8.0.0

BREAKING CHANGE: IServiceScopeFactory is now a singleton and child scopes are flat, not hierarchical. Based on #83 and dotnet/runtime#67391, the IServiceScopeFactory is now registered as a singleton. Any scope you create from it is a peer, not a hierarchy like you might see in core Autofac. Even if you create a scope from a scope, it'll use the singleton factory under the covers and all scopes will be peers.

If you are using scopes to isolate units of work, be aware that this breaks the parent/child lifetime scope relationship.

// Based on an IServiceProvider...
IServiceProvider provider = CreateServiceProvider();

// You might want to create nested scopes to track work...
var unitOfWorkOutside = provider.CreateScope();

// And later have a sub-unit-of-work scope inside that...
var unitOfWorkInside = unitOfWorkOutside.ServiceProvider.CreateScope();

// But they're NOT RELATED! They don't share a resolution hierarchy
// so cached instances in the outer scope won't be seen in the inner
// scope. You can dispose that "outer scope" without affecting the
// "inner scope" at all because they're peers, not parent/child.
unitOfWorkOutside.Dispose();

// Still works because it's not a hierarchy!
unitOfWorkInside.ServiceProvider.GetRequiredService<MyService>();

If you need to create hierarchical scopes, you will need to use native Autofac constructs.

// Based on an IServiceProvider...
IServiceProvider provider = CreateServiceProvider();

// You'll need to get an Autofac lifetime scope.
var autofacScope = provider.GetService<ILifetimeScope>();

// Use the Autofac constructs to create hierarchical lifetimes.
var unitOfWorkOutside = autofacScope.BeginLifetimeScope();

// And later have a sub-unit-of-work scope inside that...
var unitOfWorkInside = unitOfWorkOutside.BeginLifetimeScope();

// Now they're related so they'll share a hierarchy. If you dispose the outer scope...
unitOfWorkOutside.Dispose();

// ...stuff in the inner scope will not resolve because you disposed its parent.
unitOfWorkInside.Resolve<MyService>();

BREAKING CHANGE: The Microsoft.Extensions.DependencyInjection dependency is now set at 6.0.0 for all target frameworks. M.E.DI v6 is compatible with all the frameworks Autofac.Extensions.DependencyInjection targets, so your application should be able to allow this through transitive dependencies. However, if you have a hard requirement to stay on an older version of M.E.DI for some reason, you won't be able to take this upgrade.

Autofac.AspNetCore.Multitenant has been updated to account for these changes. If you are using the multitenant ASP.NET Core support and update Autofac.Extensions.DependencyInjection, also be sure to take the latest Autofac.AspNetCore.Multitenant package.

The Autofac core version reference has also been updated to 6.4.0 to make sure fixes and features from the latest are included by default. This should not be a breaking change.
