Silverlight being discontinued after having built a huge configuration app using it.

It was discontinues in like what? 2005?

Silverlight has been slated for closure since 2013?

Why build anything new in it?

@rantsauce not quite ;). It came out 2007.

@Voxera my bad! Internet years are so short

@Voxera I didn't. I used it around 2009/10 maybe? And then it basically started dying right after, with MS officially starting to deprecate it in 2012 I think.

@pleuph ok, yes 2009 it was still on the rise.

Personally I had to bad experience from flash that I stayed away, especially since I saw that firefox was adding more and more tools within the browser that I really never needed it.
