问题 I would like to know if there is a "first run" flag or similar in WP7. My app takes some stuff out of isolated storage so I would like to determine if this is necessary first time. I am currently using an if to check if the named storage object exists but this means I can't handle any memory loss errors in the way I would like. 回答1: I don't think there is a built in feature for this ... but I know what you mean :-) I implemented "first run" myself using iso storage in the open source khan
