I found out this evening (or likely knew before but had forgotten) that Edge browser does not and will not support the Silverlight plugin from Microsoft. So if you had any awesome .net code you could run inside a browser, you’ll need to fire up an old version of Internet Explorer, or possibly run Firefox (last I heard, it still supports it, but Chrome does not now either). Weird times.
You can check your version of Silverlight by going to http://silverlightversion.com and download the latest Silverlight at http://silverlightdownload.com … but don’t bother doing either of these if you’re using Edge browser!
