I,m looking for a solution to add bing layer as basemap for arcgis javascript 4.6, but I dont find any things.
Anjelina,
When you have a question about a feature that is not present in the 4.x api and was in the 3.x then you need to consult the functionality matrix:
Functionality matrix | ArcGIS API for JavaScript 4.6
Support for Bing mapping (formerly known as Virtual Earth) | Coming soon |
If you want to know when this is coming, there is no official word on the date. Most of the time esri will not give a date on things like this.
Hi anjelina ponkerat, Bing Maps support was recently added to the 4.8 release of the ArcGIS API for JavaScript. Please see here for details.
