The Intersection of Microservices, Domain-Driven Design and Entity Framework Core
Domain-Driven Design (DDD) provides much of the strategic design guidance that we can use to determine the boundaries around and interactions between Microservices in our solutions.

.NET Core 2.1.0 (along with ASP.NET Core and Entity Framework Core) will be released around May 30th, but for folks who can't wait until then and would like to get their hands on the bits a little early, read on!
The following API and behavior changes have the potential to break existing applications when upgrading them to 3.0.0. Changes that we expect to only impact database providers are documented under provider changes.
