Autofac BeginLifetimeScope

Question

I create a processing object as follows during the start of a process:

using (var lifetime = EngineContext.Current.BeginLifetimeScope())
{
    var sourceService = lifetime.Resolve<SourceService>();  
    // do things... 
}

The SourceService class depends on other objects also registered with AutoFac - through constructor injection.

Do these objects automatically inherit the same lifetimescope as its 'parent' i.e. sourceService ?

Answer 1

It depends on how they were registered.

InstancePerLifetimeScope = one per scope.

Example:

builder.Register<YourClass>()
    .AsImplementedInterfaces()
    .InstancePerLifetimeScope();
