Remove silverlight from the WP dev center website
Silverlight doesn't work properly in IE 11, so I cannot upload xap files using IE 11. I have to switch to google Chrome to publish Windows Phone Apps. I get the following message: You don't have a supported version of silverlight installed. To get the latest version....
If I try to update silverlight I recieve the message: The same version is already installed. Silverlight is enabled, etc
The Modern App of IE11 not having Silverlight support is another good reason to remove Silverlight. It would improve the Windows 8 modern UI experience, currenlty I simply don't use the IE11 app because I don't like to keep switching browsers (silverlight is in pubcenter as well).
But I can't get it to work in the desktop version either (Windows 8.1 64 bit), although it should be supported.

If you are using the Modern App of IE11, there is no Silverlight support. Use the Desktop version of IE11 instead.
