Follow the steps below to implement a provider that loads tiles from a custom source.

Create a provider class that implements VectorTileDataProviderBase.
Implement the VectorTileDataProviderBase.GetStream method so that it returns a tile as a sequence of bytes for specific coordinates in the tile grid at the specified zoom level.
Assign the provider to the ImageLayer.DataProvider property. Note that the ImageLayer.DataProvider is a content property. You can declare a provider in XAML directly after a layer’s declaration without wrapping it in opening and closing ImageLayer.DataProvider tags.
