I want to show you how easy it is to get a simple website up and running using Ooui  that is powered by Xamarin.Forms

In .NET Core 2.1 a new struct was added. It’s called  System.HashCode  and it makes generating hash codes super convenient. Have a look at this class. 

class Person
{
public string FirstName { get; set; }
public string LastName { get; set; }

public override int GetHashCode() => HashCode.Combine(FirstName, LastName);
}

We’re excited to announce the release of .NET Core 2.1. It includes improvements to performance, to the runtime and tools. It also includes a new way to deploy tools as NuGet packages.  

.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! 

Support for .NET Core 2.1 project templates. 

a .NET Core CLI tool that retrieves metadata from a web service on a network location or from a WSDL file, and generates a WCF class containing client proxy methods that you can use to access the web service operations. 

My guess is that this could be part of a long-term strategy to retire the full .NET Framework , rather than bringing any real value to .NET Core or desktop applications. 

Performance is a Key .NET Core Feature 

Added "debug all tests" and "run all tests" to the CodeLens that appears above test classes to allow running or debugging all tests in a class.
