.NETv3.5 or .NETv4?

Nov 1, 2011 at 10:14 PM

.NET v4 is out for some time now and I want to vote for porting MWv4.9 to .NETv4 and try to use the new features as much as possible.
Parallel programming should be much easier and also using a touch enable device, like a tabletPC or the new multi-touch mouse pads on laptops.

A new version of C++ is also under development. It might be worthwhile to investigate that as well.

Here's an article about parallel programming:

Here's a peak at what is new in .NET v4.5, e.g., await and async keywords, auto-vectorization and parallelization of loops in C++, and spatial data type support.


Of course, the RTM is still a ways out on .NET 4.5 as the current release is a Developer Preview.

If you are interested in the Task Parallel Library, this series of articles may be useful to you.

In a computer industry e-letter recently, I saw a recommendation to not upgrade your computer to .NET 4. Unfortunately, I don't recall the reason, I don't recall the publication, and I haven't been able to find the item by using Google.

So basically I'd recommend investigating whether .NET 4 is stable.

I found the item.  It's from a columnist at, a respected software-industry newsletter.  The item is spare, but enough to raise questions:

"I’m sticking to my stance on installing .NET Framework 4 — don’t — unless you’re running an application that needs it. There are currently few personal apps that do (Intuit’s Quicken, for example), but the number is slowly growing. (.NET 3 is installed by default with Vista, but in Win7 .NET 4 is typically installed by the application that needs it.)"
