How to store data for a ClickOnce application?
It’ll lost after automatically update or not?
http://GreatFriends.Biz (c) Suthep S. 15

 We can get directory for store data
that persist for ClickOnce application
 My.Application.Deployment.DataDirectory (String)
 Other means to DataDirectory
 AppDomain.CurrentDomain.GetData(“DataDirectory”)
 System.Windows.Forms.Application.LocalUserAppDataPath
http://GreatFriends.Biz (c) Suthep S. 16

 ClickOnce makes Smart Clients come true.
 Typically ClickOnce does not need special
configuration and coding.
 We can manually check for update
and automatically install the new version
 We can download ClickOnce partially at any time.
 We should think about Data files
 We have GUI utility named as MAGE
 What we don’t covered:
Security, Associate File Extension, Using MAGE,
Custom Prerequisites, and other more advanced topics .
