1. A concise explanation of the problem you're experiencing.

I create MVC Demo, add build Folder of Cesium-1.50 to script Folder and want to create View such as below,but when I Run it got this Error:  
Cesium.Cesium3DTileset is not a constructor  
&nbsp;&nbsp;&nbsp;&nbsp;at window.onload

2. A minimal code example. If you've found a bug, this helps us reproduce and repair it.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;window.onload = function () {  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var viewer = createViewer("viewer", "@Url.Content("~/Scripts")");  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var scene = viewer.scene;  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Cesium.Cartesian3.fromDegrees(53.9868, 26.5325, 0.0);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var tileset =  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;scene.primitives.add(new Cesium.Cesium3DTileset({  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;url: ‘[https://d35ei6ur3bjvr1.cloudfront.net/berlin/small\_untextured](https://d35ei6ur3bjvr1.cloudfront.net/berlin/small_untextured)’  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}));  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;scene.terrainProvider = new Cesium.CesiumTerrainProvider({  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;url: ‘[https://d35ei6ur3bjvr1.cloudfront.net/berlin/86bd7c93-de44-455d-9efa-a41238172216](https://d35ei6ur3bjvr1.cloudfront.net/berlin/86bd7c93-de44-455d-9efa-a41238172216)’  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;});

How are you loading in Cesium? What does the “createViewer” function look like? Make sure you’re correctly including everything as described here:
