Well, I'm having trouble developing apps in Visual Studio, my computer is 32-bit, so there's no way I can test apps with emulator, and test on my own phone, a 4-inch Lumia.
In my last project, which had everything to be a great app, I had the frustration to see it not working on devices with other types of rela, so I related this to the use of the "Grid" tag, we do in html with the divs, to separate the screen into frames and then transform those tables into tables with rows and columns.
My question does not have much to do with code in general, but rather with the use of this tag in general, can excessive use of it possibly compromise the app? There is also the StackPanel that would be a panel, but I do not really know what each one is for and how to use it, could anyone give me a light on it? Well, the rest is cool, I know how to use it, it's just this question that will not let my apps work, I've given up hope for it.
