how to set AlternateId for an asset in azure media service?

Question

I am trying to add some custom metadata to every video stored in azure media service. As part of this I am trying to change the value of AlternateId of an asset stored in Azure media service.

I could see that the key is available as part of IAsset

When you use the CloudMediaContext to Create or Encode an asset you are handed the asset back. At this point you can set the AlternateId and call Update.

      IAsset inputAsset = _mediaContext.Assets.CreateFromBlob(blob, 
                            storageCredentials, AssetCreationOptions.None);

      inputAsset.AlternateId = assetId.ToString();
      inputAsset.Update();
