ASP.NET Core AzureBlob download file with rename

I have the following code on my page:

<a class="btn-default btn" href="<AzureBlobContainerUrl>/<guid>.psd" download="@Model.FileName" target="_blank">Download 
    <span class="glyphicon glyphicon-export"></span>
</a>

@Model.FileName represents e.g. 'MyPhotoshopFile.psd'

First Problem: The downloaded file has the original GUID as filename not e.g. 'MyPhotoshopFile.psd'.

Second Problem: If the file is a e.g. PDF then Google opens the file directly in the current browser tab instead of downloading it.

Any solutions for that?

Well, thank you very much for your tips! First, the code and your advice weren't working (the C-D attribute was ignored by azure blos storage services), but after some hours of research I identified the issue:

  • AccountKind StorageV2 (general purpose v2) is NOT working with the C-D attribute
  • AccountKind BlobStorage is working without any problems

I recreated the blob storage and used the legacy BlobStorage account type. With this the ContentDisposition Attribute is working.

For the first problem, try setting the Content-Disposition property on the blob. If you're using the C# SDK, then grab the blob and you can set the C-D using something like this:

blob.FetchAttributes();
blob.Properties.ContentDisposition = string.Format("attachment;filename=\"{0}\"", yourFileName);
blob.SetProperties();

Based on this older question (Chrome Download Attribute not working), the "download" attribute in Chrome behaves differently based on the C-D, so setting this explicitly will likely solve your second problem.
