I’ve been spending the past few weeks learning Flex and Air. It’s so similar to WinForms that it’s more an exercise in learning the syntax differances than the big picture.
Generally I’m finding it really fun and easy and if only I had more time I’d be done with the alpha launch of my product.
Adobe has done an excellent job of supporting and promoting these technologies and I’m finding it significantly easier to learn Flex and Air than it was to learn C# when it first came out.
