Using Autofac as DI container about cqrslite HOT 4 CLOSED

It looks like Autofac has some built in support for decorators. Maybe you can try it?

I do however find it strange that the builder method don't work as it is. You could try making a builder method for Session instead and see if it works?

Adapters and Decorators

Tried it with the Autofac decorator, but still no luck. I opened a question on StackOverflow about this, explaining what I tried.

Hi Gaute,

I was able to resolve the circular dependency stuff (was related to NServicebus).

I have another question. In the sample implementation, you register a scoped instance of the CacheRepository. Does this ultimately mean that for every command that is handled, a new CacheRepository is created? So if you then Get an aggregate from the session (and as a consequence from the CacheRepository) would you agree that an aggregate will never be retrieved from the cache, unless you put it in there first within the handler?

So in this code:

      public async Task Handle(DeactivateInventoryItem message)
        {
            var item = await _session.Get<InventoryItem>(message.Id, message.ExpectedVersion);
            item.Deactivate();
            await _session.Commit();
        }

the InventoryItem will not be in the cache? It will be retrieved from the event store however.

Even if the Cache is scoped, both System.Runtime.Caching.MemoryCache used by .NET Full framework and Microsoft.Extensions.Caching.Memory.MemoryCache used by .NET Core stores the events in a globally scoped cache. So it will be cached, but feel free to try with a debugger to make sure.
