wpf - Modify Connection Strings the first time I run the app -


i want provide feature opens dialog first time program opens , allow system admin change application connection strings.

so far, haven't had success in doing so.

  • i can't use user settings. want users connect same database.
  • the application settings read-only.
  • seems can't modify app.config file , save physical disk. far can tell, changes applied memory.
  • i thought writing them different file program might run uac issues.

how can save these strings file , access them? prefer use app.config because entity framework contexts can initialized using connection string names.
