Asp.net core 3.0: Introduction and brief information about its new features
ASP.NET Core, developed by Microsoft and the community is a free and open-source web framework and higher performance than ASP.NET. It runs on both the full .NET Framework, on Windows, and the cross-platform .NET Core. ASP.NET Core is the versatile framework and can be used to build all kinds of software including Web applications, Mobile apps, Desktop applications, APIs, Cloud services, Games, Microservices, and IoT applications.
.Net Core 3.0
ASP .NET Core 3.0 is still in preview 7. This version is scheduled to release on September 23, 2019.
It adds support for C# 8.0 and Windows Desktop.
The framework is a complete rewrite that combines the previously separate ASP.NET MVC and ASP.NET Web API into a single programming model. The three main themes of .Net Core 3.0 are desktop workloads and UI interop, artificial intelligence and machine learning and Web app development productivity. The new support for desktop development with Windows Presentation Foundation (WPF) and Windows Forms (WinForms) has been a much-discussed feature of the upcoming .NET Core 3 offering.
.NET Core 3.0 SDK Size
The .NET Core SDK is smaller with .NET Core 3.0. The main reason is that SDK is built in a different way i.e, by moving to purpose-built “packs” of various kinds (reference assemblies, frameworks, templates). In previous versions (including .NET Core 2.2), SDK was build from NuGet packages, which included many artifacts that were not required and wasted a lot of space.
