Description Dominique 2011-10-24 20:32:53 UTC
Rather than a bug this is an enhancement, but I couldn't find the option for enhancements, I hope you can move it to the right place.


IsolatedStorageSettings is missing form System.IO as per Microsoft's documentation...

http://msdn.microsoft.com/en-us/library/system.io.isolatedstorage.isolatedstoragesettings(v=vs.95).aspx

Please add it in.

-> enhancement

This type is available on Silverlight (not the full framework) inside System.Windows.dll. I guess we could add it into monotouch.dll (that would work for compile-time compatibility).

We do have an implementation on Moonlight - but that's likely not a good idea to use it "as-is" since:

* the System.IO.IsolatedStorage API from Silverlight is different from the full framework (on which the MOBILE profile is based);

* for compatibility with silverlight the moonlight version uses the DataContractSerializer which is not ideal since it would add another dependency to monotouch.dll

OTOH the linker has been updated to better detect XML/DataContract serialization usage.

Thanks for moving it to an enhancement.

The reason why I'm asking for it, is people porting their games from XNA and WP7 to MonoGame expect it to be there. For example - http://stackoverflow.com/questions/3962673/can-an-xna-game-use-isolatedstoragesettings-for-wp7
Comment 3 Sebastien Pouliot 2011-10-26 08:48:30 UTC
I'll look into it :) since I did the original code and since it can become a linker test case too

Eric, is this something you already had on your radar ?

Not currently, no.
Comment 6 Chris 2012-12-21 10:51:20 UTC
Please add this as without it porting from Windows Mobile and Mono Android is more difficult that it needs to be.
Comment 7 Roger Peters 2013-02-25 23:42:58 UTC
I'd just like to echo the request for support for IsolatedStorageSettings. Now I need to figure out how to serialize my objects (and their images) without it..
Comment 8 SCSMobility 2013-03-25 10:46:47 UTC
Supporting also Roger and others. Support would be really needed and would help our work. Now we need to make workarounds for each target to overcome missing functionality.
Comment 9 SCSMobility 2013-03-28 06:34:30 UTC
Any updates from on Xamarin behalf, do you have the latest estimate for this?
Comment 10 Sebastien Pouliot 2013-03-28 09:01:25 UTC
There's no immediate plans, for the typeitself or other parts oif System.Windows.dll.

However the source code for Moonlight's IsolatedStorageSettings [1] is available (small and fully managed) and can be included inside your own applications (or built in a seperate assembly for reuse* accross projects).

It might require a few modifications since Silverlight API for System.IO.IsolatedStorage is not 100% compatible with the "desktop" version of the Framework (which Xamarin products follows). OTOH it should be very small changes (the source itself is very small).

* If anyone does port it and wants to share then I suggest you to submit it to the component store.

This is not part of NET Standard and will not be added inside the SDK.
