Entity Framework Core 2.0 introduces global query filters that can be applied to entities when a model is created. It makes it easier to build multi-tenant applications and support soft deleting of entities. This blog post gives a deeper overview of how to use global query filters in real-life applications and how to apply global query filters to domain entities automatically. 

Today, we are releasing updates to the .NET Core SDK, included in Visual Studio 2017 RC. You can also install the .NET Core SDK for use with Visual Studio Code or at the command line, on Windows, Mac and Linux. Check out the Visual Studio blog to learn more about this Visual Studio 2017 update.

ASP.NET Core 2.0 – What’s New  

In short, domain events help you to express, explicitly, the domain rules, based in the ubiquitous language provided by the domain experts. Domain events also enable a better separation of concerns among classes within the same domain. It's important to ensure that, just like a database transaction, either all the operations related to a domain event finish successfully or none of them do. Domain events are similar to messaging-style events, with one important difference. With real messaging, message queuing, message brokers, or a service bus using AMQP, a message is always sent asynchronously and communicated across processes and machines. This is useful for integrating multiple Bounded Contexts, microservices, or even different applications. However, with domain events, you want to raise an event from the domain operation you are currently running, but you want any side effects to occur within the same domain. The domain events and their side effects (the actions triggered afterwards that are managed by event handlers) should occur almost immediately, usually in-process, and within the same domain. Thus, domain events could be synchronous or asynchronous. Integration events, however, should always be asynchronous.
