I followed the procedure as given and when I try to run the application, widget gets created but map doesn't appears.
"Maps key. Please create a new key for the application as soon as possible and prior to deployment by visiting https://www.bingmapsportal.com/, and provide your key to Cesium by setting the Cesium.BingMapsApi.defaultKey property before constructing the CesiumWidget or any other object that uses the Bing Maps API."
The I generated new key and replaced it at 'BingMapsApi.defaultKey', then also it didn't worked. Also i tried by replacing the key where default key was hardcoded.
Still getting same error.
OS used: Mac & Win 7
Browser: Firefox and Chrome
Kindly suggest some solution.
