Answer 1

You can use the same tool that you can use for asp.net applications.

Make sure to have a backup before you do the following!

1. Look here: 'C:\Windows\Microsoft.NET\Framework' for your version or just the newest.
2. Open the folder of your version
3. Search for 'aspnet_regiis'
4. Right-click it and select properties then copy the path of the location
5. Now rename the 'app.config' file in your project to 'web.config' (you can do that in visual studio)
6. Open the command prompt
7. Type in '\aspnet_regiis -pef "connectionStrings" '
8. Press enter
9. It should give you something like 'Successfully encrypted' or so
10. Now you can rename your 'web.config' file back to 'app.config'

Now you can look into the app.config and see that the connection string is encrypted.
