7.0.0

Changes

• Updated everything to run on Orleans 7.x
• Migrated to native .NET hosting API
• Added support for native serialization for ActorPath, StreamPath, ActorRef, StreamRef, ClientRef
• All samples were migrated to use IInvokable instead of InvokeMethodRequest in MayInterleave static callbacks
• DeactivationReason was added to Deactivate message
• Separated lifecycle messages sent on grain and state activation/deactivation via Activate.State and Activate.External static messages

Breaking changes:

• Removed support for IGrainActivator in favor of native grain activation services
• Removed support for stream filtering since it's not supported by Orleans streaming api
• Removed implicit stream subscriptions via StreamSubscriptionAttribute in favor of native ImplicitStreamSubscription and RegexStreamSubscritpion attributes
• Roundtrip serialization checking in TestKit now accepts IServiceProvider and uses serializer registered in container instead of direct use of not available in 7.x Serializer class
• CreateObservable() on IActorSystem is now synchronous and returns reference to IClientEndpoint instead of Task<IClientEndpoint>

Bug fixes

• Fixed concurrency bug with key no found exception fired on timer removal when the one-off timer was fired before await
