Microsoft just announced the upcoming availability of LightSwitch. Beta 1 is scheduled for August 23rd 2010. You wonder what it is? Check http://www.microsoft.com/visualstudio/en-us/lightswitch.
Apparently (and from the short demo I just saw), it is a big wizard that generates SilverLight applications that you can then customize even more.
I believe that this product as a niche and it won't fit everybody's requirements but it will surely help some others. So lets wait August 23rd to start downloading it and test it!
