Restoring the local database involves submitting a background transfer request to download the previously uploaded file from the server. The file is downloaded to a temporary location in isolated storage, the existing local database is disconnected, and its file is replaced.
The RestoreDatabase method begins by creating a temporary directory where the downloaded .sdf file can be placed by the BackgroundTransferService:
const string downloadPath = transferDirectory + "/" + localDatabaseName;using (IsolatedStorageFile isolatedStorageFile = IsolatedStorageFile.GetUserStoreForApplication()){ if (!isolatedStorageFile.DirectoryExists(transferDirectory)) { isolatedStorageFile.CreateDirectory(transferDirectory); ...
