Like define in XAML file?
I seen couples of example they were on define in code and stores into App.xmal, but I am just thinking when people look at the setting, they will look into App.xaml, not the code-behind.
And another thing is, I don’t want to declares some property on code-behind, some in xaml, some in project property, it made things hard to find.
Is there proper place or way to stores the connection string?
App.config. It is rather nonsensical storing this in a UI-specific XAML file.
