.NET Framework 4.0 and Dublin

At the end of September 2008, Microsoft unveiled that the next versions of Visual Studio and .NET Framework would span across not only the client and server operating systems but also across services and devices. Visual Studio 2010 and .NET Framework 4.0 are expected to drop either in late 2009 or by the first half of 2010, even though Microsoft failed to confirm a delivery deadline. As far as the next iteration of its runtime environment is concerned, Microsoft is cooking .NET Framework 4.0 while planning a synchronization with the evolution of Windows Server, namely Windows Server Dublin.

“Updates to the next versions of Windows Communication Foundation (WCF) and Windows Workflow Foundation (WF) are focused on reducing complexity for developers by providing better support for Web 2.0 technologies like REST, POX and ATOM, and increasing performance and scalability in the process. In fact, early tests show these improvements to WCF and WF are, at a minimum, enabling 10X the perf and scalability - and to think we’re still fine tuning here! Second, 'Dublin' makes it easier to deploy, manage and scale these next-generation applications,” explained Steven Martin, Director, CSD Product Management Microsoft.

Windows Server "Dublin" is a collection of enhanced capabilities added to the Windows server platform which will expand to also take Internet Information Services (IIS) to the next level. The end purpose of the improvements planned for the Windows Application Server is to permit developers to handle composite applications in a much simpler way than they can today. Microsoft is in fact looking to streamline processes including installation and management as well as the scalability of composite solutions.

“We will deliver a Community Technology Preview (CTP) of Windows Workflow Foundation, Windows Communication Foundation, and 'Dublin' technologies at the Professional Developers Conference in October 2008; this will allow us to begin receiving broader feedback from customers and partners. We are committed to driving and prioritizing our development efforts based upon customer and partner feedback; the feedback from this CTP and other customer programs will help inform us as to the exact timing of our beta and RTM,” Microsoft indicated via the Dublin NET 4 Overview whitepaper.
