Microsoft designated Fx2 for the development of the Windows 8 application of MercadoLibre for LATAM.  

The application allows users to navigate through the MercadoLibre category tree, access published articles, search for content in the product catalog, share information on social networks, among other features. 

Also the interaction is 100% based on REST API public services of MercadoLibre, which in some cases was modified for a perfect fit with the application and search. 

The application was published less than 3 months before the official launch of Windows 8 and is currently still valid and with an excellent average of downloads.
