Thanks Mike,

in this case we already have a desktop based application used in the office written in C# using WPF. The mobile app needs to be used by drivers who deliver packages and may not be able to access the web from wherever they are. The cost of providing the devices with remote web access is also a cost that management does not want to have to incur.
