Deployment of LocalState folder

I'm using the LocalState folder to enable caching for my Windows 8 application. To provide sample data (the application uses a webservice to gather it's data), I would like to provide a default bunch of data already cached.

Can I provide sample data for LocalState that will be in the application package?

Here is some sample JS code - should be able to convert to .NET fairly easily - use async/await in place of the Promises.

WinJS.Application.local.exists('somedata.json').done(
               function (found) {
                   if (!found) {
                       return copyStartData('somedata.json');
                   }
               }
           );

function copyStartData(copyfile) {
        return Windows.ApplicationModel.Package.current.installedLocation.getFolderAsync('startdata').then(
            function (startData) {
                return startData.getFileAsync(copyfile).then(
                    function (file) {
                        if (file) {
                            return file.copyAsync(WinJS.Application.local.folder);
                        }
                    });
            });
    }

The function takes the name of a file you want to copy from your install package to the users local machine.

You could put the file(s) into your package and then on startup check to see if there is already data in the Local Folder, if not, copy/populate it from the package storage (see CopyAsync, for instance). If so, do nothing.
