Exception thrown when trying to access Profiles

Question

I've just been doing a quick demo silverlight app for mesh which I was planning on making the same as my console app. However, I'm getting an exception thrown whenever I try and access the Profiles object of the Live Operating Environment. I have set the application's settings as described by Danny, but this does not change anything. The start of my code is this:

InitializeComponent();

MeshApplicationService meshApp = Application.Current.GetMeshApplicationService();

// once mesh contents are loaded we get callback

meshApp.LoadCompleted += new EventHandler(meshAppLoaded);

meshApp.Load();

LiveOperatingEnvironment loe = meshApp.LiveOperatingEnvironment;

// This gets the Messenger PSM

Profile prof = loe.Profiles.Entries.Single(e => e.Resource.Title == "GeneralProfile");

var somethingelse = (GeneralProfile)prof.Resource.ProfileInfo;

When debugging, just looking at the loe object, the Profiles attribute just says that it threw an exception.

Any thoughts?

Hi Scott,

Are you running this mesh app in Live Desktop (in the browser) or on the local LOE on your local desktop?  I don't think Profiles (or Contacts) are supported yet on the local LOE.

Hi Danny,

This is when using the Live Desktop, not the local Mesh client.

I suspect this is permissions issue. can you verify that using LivefxResourceBrowser that you have following Permission, highlighed:

<InstalledApplicationResourceContent xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://user.windows.net">

<Offers>

<Offer>

<OfferName>DeveloperCTPProfiles.Read</OfferName>

Danny has provided a work around for fixing permissions:

Hi Vikas,

Thanks for the reply. I will verify with the LivefxResourceBrowser when I'm next on the PC with my project on it. I did however already do the steps described in Danny's post and the permissions were all set correctly after that (including access to the profiles).

In the Apps settings on the website, I have the following:

Permissions

Read access to my Windows Live Profiles Read access to my Live Mesh Devices Read and update access to my Windows Live Contacts Full access to my Live Mesh User News

I can still double check with the resource browser, but they do look correct there.

PS. It was me who 'started' the similar thread you mentioned :)

 Hi Scott,

I have seen the same result as you did when trying to access Profiles with the correct permissions within a Mesh-enabled Silverlight application. 

I have then attempted to implement the same steps through WPF Application and I was able to access the Profiles object after connecting to LiveOperatingEnvironment by passing in the correct Network Credentials.

This behaviour reminded me the response given for New MeshObject does not look initialized and Add throws thread. Vikas, can you please confirm whether this is the expected result in the case of Profiles too?

Thanks,
Mine

Answer 7

Scott,

I've repro'd this issue here.  It looks like meshApp.LiveOperatingEnvironment.Profiles is broken in the Silverlight Live Framework client lib.  Any access to the Profiles property throws, even with DeveloperCTPProfiles.Read access.  We're investigating.

Please log this as a bug so you get credit for finding it. ;>
