## What is CSCS Native Scripting?

CSCS (Customized Scripting in C#) can now be used for native mobile development.

This App contains a CSCS interpreter that you can use to play around with CSCS. There are also a few pre-set examples.

You can create any CSCS scripting code in one tab, "Create", and then see the results in another tab, "Run".

AutoScale();
SetBackgroundColor("cyan");

AddOrSelectTab("Create", "test.png", "test2.png");

__locComboFiles = GetLocation("ROOT", "CENTER", "ROOT", "TOP", -100, 40);
AddCombobox(__locComboFiles, "__comboFiles", "center:white:clear", 350, 60);
__optionsComboFiles = {"Sandbox", "Hello, World!", "Ads", "Busy Indicators", "Unit Tests"};

AddWidgetData(__comboFiles, __optionsComboFiles, "", "center");
SetFontSize(__comboFiles, 13);
SetValue(__comboFiles, "text2", "Done");
SetValue(__comboFiles, "alignment", "center");
AddAction(__comboFiles, "comboFilesChanged");
