Windows 10
A library on Codeplex. Been a long time coming: Arduino sketches and UWP class libraries and apps, focused upon scanning a phone keypad as input (Bluetooth serial) to a UWP app running on a phone, desktop or IoT-Core device.

AppInstall can be used to install Appx packages on an IoT-Core device This blog covers an updated version of the toolkit for use on the latest Winsider IoT-Core builds.
The Week or Two That Was
DAVID JONES V1.1
Some of the issues I have been looking at over the last week or so.
In the previous two blogs I discussed using the Web Portal running on a Windows 10 Phone to remotely or in-phone install and Universal Windows Platform app. In this blog I discuss options for install UWP app packages on Windows 10 IoT devices. This is a work in progress as I have not had success some of these methodologies.
An issue has arisen with the last two Fast Track Windows 10 Mobile OS versions this week. You can’t deploy apps from Visual Studio to phones with those versions. Jump off Fast Track for now to Slow Track or “slower”. If you have one of these versions on your phone there isn’t a simple way to unwind. The problem as I see it is one of connectivity and sounds a bit like the issue we had last November with IoT-Core.
After an absence from significant IoT-Core activity, whilst working on a significant phone app (as blogged here) I’m back in the IoT-Core space. Things have changed for the better so here goes. This blog covers my experiences with getting a RPI3 going with the latest Technical Preview build. Tools are now available to simplify setup and there is now a Remote Viewer. As a test UWP app, I have used (after a small modification) the Icons app on Codeplex, Universal Windows 10 SDK App Icons app as blogged in a previous blog. The app was modified because popups (as in MessageBox) are not supported in IoT-Core (Use thereof can cause an app crash in later OS versions). This feature change is covered.
Universal Windows(10) Apps settings is easy. Its simple to specify as part of the build, save them to storage, get them back and modify .. I mean dead easy!
It was simple enough to get access to a Microsoft SQL Server from a Web Service when all were running on the same machine. You use Windows Authentication. But when the services are both running locally, with the user running a Windows 10 Universal app that calls the web service, they won’t be logged in an so the web service needs credential for the SQL service.
I’m creating a Windows 10 Universal Phone App that talks to a Web Service to post an entity (object) in Microsoft SQL Server running on the same machine as the Web Service. Initially did all including the app on my laptop using localhost as the network target. Solved the SQL Server credentials .. OK. But when I switch to using the laptop’s system name or its IP address (all still running on same machine) got Network Access Required error.
In developing a Universal Windows app, when you add an existing XAML and its Codebehind page, they often end up unlinked in the Solution Explorer. This limits the ability to autogenrate event handlers in the codebehind page for UI elements.Spaso Lazarevic has a good solution that involves a little editing of the project file.
