'Tis the season for gift giving, and we need a solution to share images of our gifts! One problem though: we can only share png files.

For this challenge, create an Azure Function triggered by Azure Blob Storage that will verify that each photo uploaded to our Azure Blob Storage container is a png; if it is not, delete the photo from the container.

[FunctionName(nameof(GiftPhotoValidationFunction))]
public static async Task Run([BlobTrigger(_containerName)] CloudBlockBlob blockBlob, ILogger log)
{
    log.LogInformation("Validating Gift Image is a PNG");

    if (blockBlob.Name.EndsWith(".png", StringComparison.InvariantCultureIgnoreCase))
    {
        log.LogInformation("Confirmed PNG");
    }
    else
    {
        log.LogInformation($"Photo {blockBlob.Name} is not a PNG");

        log.LogInformation($"Deleting {blockBlob.Name} from container");

        await blockBlob.DeleteAsync().ConfigureAwait(false);

        log.LogInformation($"Deleted {blockBlob.Name}");
    }
}
