Who doesn't love a good DIY (Do It Yourself) IoT project? There are so many interesting things that we can do with a few components and a little creatively. In this episode, Cam Soper comes on to show us how he automated his home with .NET Core, Hubitat, and Azure with his open source project called Puppet.

Azure Maps Weather services (https://aka.ms/iotshow/AzureMapsWeatherService) add a new layer of real-time, location-aware information to Azure Maps portfolio of native Azure geospatial services. Bringing Weather Services to Azure Maps means IoT developers have a simple means of integrating highly dynamic, real-time, historic and forecasted weather data and visualizations into their applications through their existing Azure subscriptions. The Weather Service APIs for Azure Maps are brought to life in partnership with Accuweather. Weather is a critical factor for many scenarios—whether it's to ensure the safety of mobile assets, model and forecast need for renewable energy, or predict risk and assess claims in the insurance industry. Outi demonstrates how a few of these APIs can be used to enhance data visualizations with radar and infrared map overlays with an Azure Maps Web SDK, and how call APIs to make weather-based decisions with current and forecast based weather, as well as weather along route.

Join Dona and Sarah in this amazing episode where we talk to Ryan Jones, the master of the Common Data Service. The Common Data Service provides a 'Home of Applications' across the Power Platform, and we discuss what power this gives and why this is SO important to companies looking to take their app making to the next level.Ryan Jones is the Group Program Manager at Microsoft, managing all things Common Data Service and has been about from the very beginning of Power Apps. We also learn some fun facts about Ryan that you may not already know! (You will have to watch to find out!). Ryan is also a big supporter of the community and has had many engagements across the world, sharing knowledge about the Power Platform.

This week, James is joined by friend of the show Gerald Versluis, Xamarin.Forms Engineer, who shows off one of the coolest feature ever for app developers and library creators, Source Link. When a library is Source Link enabled you can debug INTO the source code when you are running debugging your app. This helps you diagnose issues faster than ever, check it out.

In this episode, Robert is joined by Phil Japikse for part 4 of a 5 part series on Entity Framework Core. Aimed at folks new to EF Core, Phil shows how to start with an existing SQL Server database, create entities/objects for each table and then how to perform basic CRUD operations on the data. Querying related data is simple in EF Core. In this episode, we demonstrate creating joins in our LINQ queries with Include and ThenInclude. We also discuss how you use projections to shape the queried data into other objects, anonymous or strongly typed. Find the sample code here. Episode list: Part 1: Working with Existing Databases. We scaffold the DbContext and the Entities from the Northwind Database, discuss navigation properties and relationships.Part 2: Change Tracking. Change Tracking is one of the most compelling reasons to use an object-relational-mapper (ORM) like EF Core. In this episode we discuss how the change tracker works, see it in action, as well as load data outside of the change tracker.Part 3: Basic Queries. This episode covers querying data using EF Core. We discuss the basics of Where clauses, retrieving single items or lists of items, as well as when queries actually execute.Part 4: Querying Related Data and Using Projections (this episode). Part 5: Putting the CUD into CRUD. Wrapping up our starter series on EF Core, this episode covers adding, updating, and deleting data.

Even as threats to IoT devices increase, very few of them are being designed with security in mind. Azure Sphere introduces a trusted and secure platform to build software upon, combining the security of open source with Microsoft's Seven Properties of Highly Secured Devices. Let's walk through our security model and what it takes to keep a system secure for the next decade. Learn more: https://aka.ms/iotshow/defenseindepth

AI on IoT is moving from the cloud to the edge, running models closer to the data. Traditionally the hardware to run these models on the edge has been powerful, with GPUs or compute sticks. But what if you could run a model in only a few kilobytes of memory on a tiny micro-controller drawing less than a milliwatt of power? In this video we look at doing just that, training a wake word model in the cloud using Azure ML Studio, then compressing it to 18KB and running it on an Adafruit EdgeBadge, a small, low-powered micro-controller based device.

Let's take a step back in a new mini-series that I like to call Xamarin.Forms 101. In each episode we will walk through a basic building block of Xamarin.Forms to help you build awesome cross-platform iOS, Android, and Windows applications in .NET. This week we take a look at different controls you can use to get boolean, incremental, date, and other types of values from your users.
