What are the latest frameworks/libraries between a C# application, a SQL-server DB, fix/mobile machines and PLC technology?n

For some time, I'm working on some C# applications. They are communicating with SQL-server databases and PLCs and the results are displayed on engines, mostly (portable) computers. I'm looking for the most recent frameworks/libraries, which define the interfaces between those technologies. Current interface with SQL-server databases: first it was Linq2SQL, now it's EF (Entity Framework), handled using Telerik Openaccess. Current interface with PLC technology is Kepware, using so-called OPC servers and items. Current displays are handled by XAML technology, sometimes in combination with DXF. I would like to improve the displays to be shown on smartphones. If you think "Dude! How oldfashioned can you be!", then please refrain from downvoting and mention some more recent technologies
