Error while getting Thumbnail from ContactPicker: The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)

Question

Hi,

I am using following code to get Thumbnail -

1. private async void GetThumbnail(Contact contact)
2.         {
3.             if (contact.Thumbnail != null)
4.             {
5.                 IRandomAccessStreamWithContentType stream = await contact.Thumbnail.OpenReadAsync();
6.                 if (stream != null && stream.Size > 0)
7.                 {
8.                     Thumbnail = new BitmapImage();
9.                     Thumbnail.SetSource(stream);
10.                }
11.            }
12.        }

At line 5 it is throwing this error. As suggested on different blog posts, I tried turning off the Firewall but no luck. Please suggest.

Update

I found that using following code works, but it is Obsolete class

var contactPicker = new ContactPicker();

var contactInfos = await contactPicker.PickMultipleContactsAsync();
            foreach (var item in contactInfos)
            {
                var imgStream= await item.GetThumbnailAsync();
            }

 Can anyone explain why this is working here?

Hi Rahul534,

Take a look at the documentation first: Quickstart: Selecting user contacts

It seems that your code are correct, the exception thrown is a COM error message, could be a installation issue or a timing issue, but I believe if you running the same code in another machine, should be ok.

Answer 2

I am having the same problem. As it is occurring on my dev machine, I really need to fix the problem. I don't want to have to use the obsolete method as I'll still have to fix the problem beyond 8.1 anyway.

Do you have any suggestions for investigating/resolving the  issue?
