Microsoft is moving ASP.NET Core 3.0 to general availability, marking a significant new entry in the course catalog for .NET web developers. The announcement is set for September 23rd at .NET Conf 2019, which will be held virtually this year. For UK developers, there are local events scheduled around the world, including a watch event hosted by Twilio's Layla Porter. To prepare for the new version, developers can refer to articles and guides on ASP.NET Core 3.0, such as those written by Shawn Wildermuth and Andrew Lock, or follow breaking news on GitHub's aspnet/Announcements channel. Additionally, Microsoft has released a step-by-step guide for converting from ASP.NET 2.2 to 3.0, along with other resources, including an episode on microservices on Channel 9.
