Adding services after container has been built
Since ContainerBuilder.Update has been deprecated, the new recommendation is to use child lifetime scope.
Adding Registrations to a Lifetime Scope
Autofac allows you to add registrations “on the fly” as you create lifetime scopes. This can help you when you need to do a sort of “spot weld” limited registration override or if you generally just need some additional stuff in a scope that you don’t want to register globally. You do this by passing a lambda to BeginLifetimeScope() that takes a ContainerBuilder and adds registrations.
using(var scope = container.BeginLifetimeScope(
builder =>
{
builder.RegisterType<Override>().As<IService>();
builder.RegisterModule<MyModule>();
}))
{
// The additional registrations will be available
// only in this lifetime scope.
}
Working with Lifetime Scopes
Yes you can, using the Update
method on ContainerBuilder
:
var newBuilder = new ContainerBuilder();
newBuilder.Register...;
newBuilder.Update(existingContainer);
