I used .NET to realize some custom solutions for the Windows OS environment acquiring basic knowledge and experience.
These are some of recent custom solutions :
A group of services hosted by Internet Information Services (IIS) using Windows Communication Foundation (WCF) to serve data from a MS SQL database to an Android application.
A standalone application able to fetch data (location positions) from an MS SQL database serving a remote tracking solution and publishing these data into the web in real time.
A standalone application able to perform standard certification test ATP ( tables and graphics) to refrigerated trucks : 24 temperature probes connected via a dedicated hardware using Modbus protocol.
