When I am running my out of browser SL app, it works fine on local machine, but when I publish on server, it won't update the latest changes as it does for local app. I am using CheckAndDownloadUpdateAsync to check and update and works fine locally.

Any solution would of great help.

I'm running in OOB mode, I have selected Elevated Permissions, and have given the user group Everyone full control of the Pictures folder in my web site, and I still can't read in the jpg names from it!!! This is infuriating. I just want a dynamic bunch of thumbnails from what whatever is in the folder. My third party web hoster doesn't give me access to anything except the folders I create within my site. There is no concept of My Documents when you are running on someone else's server. So how do I show the user a bunch of thumbnails?

Does elevated trust in Silverlight also provides some elevation in MAC OSX?

I have signed my OOB app with my validated certificate and use elevated permissions. However, I can't launch my app in FullScreen mode - only with a maximised window? I want it to load directly into fullscreen - is this possible?

If you click on the "Start Tourney" button it goes into FullScreen mode but I want it to work with no user interaction....

No permissions for AppData!!!

..applications can read all the user's private documents but cannot store configuration files (or whatever) in AppData ?

If i plan to use OOB usually i will need to store an offline db for later sync, or maybe configuration files, or cached photos for a catalog...all things that deserves an AppData space or something similar!

where is supposed to store this files with OOB ?

At this point this restriction seems very ugly, especially if i can do this things "non-natively" with COM ... but why i need to use COM in this case???

Remove this restriction...is a joke...!

Now SL OOB apps are forced to write to My Documents, which is IMO a really bad place for programs to write stuff to without interaction. My Documents is the one place on the system where the user stores their files, now the folder should be called "Program's Documents" and the user should place their files somewhere else.

@olandt: you can debug out-of-browser by either attaching the debugger to the sllauncher.exe, or by specifying "Out-of-browser application" under the Debug tab of the Silverlight project properties.

@Gabe: AFAIK No...

Is there a limit to the space you can use in the user folders (My Videos, for example)?

@Fallon: Sentence refers to what you can do w/o interoperating with COM objects, e.g you can't natively interact with hardware resources

Elevated permissions also allow a user to use all of the alphanumeric keys while in full screen mode.

I'm not sure I understand the statement "it’s worth mentioning that you can’t still have full control of local machine".

If you can access COM objects, there should be no limit to what you can do, although that requires that you build COM apps.

Am I missing something?

The restriction on file access to the official User folders is maddening. It greatly interferes with the SL app's ability to monitor collections of images and large binaries, for example, which are rarely stored in My Docs, often residing on multiple portable drives. Non-trust and full-trust make sense, but the entire concept of moderate trust seems useless to me.

I was having just this discussion with a Silverlight techie from Microsoft just last week - I don't think the limits imposed by the OOB model are actually a bad thing.

In today's user environment, especially under Win7 or Vista, it definitely pays to behave properly in terms of requesting security access and permissions. In the majority of cases the user shouldn't need to (and won't have access to) many areas beyond their own user profile so it makes sense that apps, whatever their flavor, adhere to the same restriction.

In situations where elevated (or Elevated) permissions are required, perhaps this will make developers think more about architecture; about WCF or whether to use WPF instead (Click-once deployment is superb for WPF apps, for example, it's a real paradigm shifter for deployment in my opinion).
