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!
