NCX-Core is an application that allows you to quickly download and update software by NinjaCheetah and other small developers. It now has features such as NCX-News, which will tell you news about new programs that have been added or updated. It was the first major app I made and was the first program to be rewritten with a WPF GUI on top of .NET Core, and then later .NET 5.
NCX-Core gets its applications from our store JSON file, simply named "XStore". That file is hosted here, and if you'd like to request an addition or change, feel free to open an issue there.
