Microsoft Introduces .NET Core
New submitter I will be back writes: Microsoft's Immo Landwerth has provided more details on the open source .NET Core. Taking a page from the Mono cookbook, .NET Core was built to be modular with unified Base Class Library (BCL), so you can install only the necessary packages for Core and ship it with applications using NuGet. Thus, NuGet becomes a first-class citizen and the default tool to deliver .NET Core packages.
As a smaller and cross-platform subset of the .NET Framework, it will have its own update schedule, updating multiple times a year, while .NET will be updated once a year. At the release of .NET 4.6, Core will be a clear subset of the .NET Framework. With future iterations it will be ahead of the .NET Framework. "The .NET Core platform is a new .NET stack that is optimized for open source development and agile delivery on NuGet. We're working with the Mono community to make it great on Windows, Linux and Mac, and Microsoft will support it on all three platforms."

Java is still in a first major version. Latest release is 1.8.0_xxx
"There is no large scale .NET app I know of"
Ever heard of stackexchange?
Why should I have to use a third party library to get decent date support?
I've questioned that myself while working in .NET. Ever needed to write time zone aware code?
Date libraries, as it turns out, are rather monstrously difficult to make. While .NET did a great job for the common stuff, uncommon things can be painful, error prone, or impossible.
The fullest solution I've found so far is Noda Time, which is actually based on the Joda-Time Java library. It feels out of place with a number of Javaisms still in it, but it provides a much richer functionality and better separation of concerns.
