Get image from zure storage

I am trying to achieve a similar experience as in your CardView demo with the cities. The images are stored as block blobs in an Azure storage account. The blobs have tags, which i want to expose , similar to the meta from the demo where we have city name, population, country).

As far as i saw, there is no direct integration for CloudBlockBlob, so i am trying to place this in a byte array in order to display. Yet the outcome is an empty box in the grid, for each item from the container. the blobs are correctly downloaded, verified by writing the fileContent byte array to disk via filestream.

Any idea on how to achieve this?

Thank you!
