Universal Windows Platform is almost new kid on the street and it’s time for developers to find out what it is, how it works and why to bother. In this post I make short introduction to UWP for developers. I also share some of my thoughts about platform and point out some useful resources that help you to get started.

When new Microsoft Azure services come they usually have REST API-s available. Of course, there are usually client libraries available too as NuGet packages but usually not for every .NET flavour. Although Microsoft has plans to publish libraries for CoreCLR too it doesn’t happen always fast. Let’s see how REST API-s work and how to prepare for using them.

Planning for search is mandatory first step when starting building search index. If we build search indices as we go we easily end up with messed up and hard to use indices. And even worse – we may end up with very complex search queries that need way more resources than we expect. This post goes through simple analysis of example beer store search index and shows how to create Azure Search index for products.
Read moreI have local database where I insert some data and I want this data to be available also in cloud. As a lazy guy I don’t want to synchronize data manually. After setting up local and cloud databases I activated Azure Data Sync to just find out that it conflicts with EF7 insert and update queries. As I don’t have many tables and my database is pretty small I invented simple workaround.

In one of my systems I’m using background process that hosts jobs that import and update some data and communicate with external services. These jobs are running after some interval or on specific moments. I generalized the common base part of these jobs so I can handle them as one in different background processes like Azure worker roles and Windows services. This blog post introduces my work and shows real-life implentation of jobs base.

Our beer cooling solution is not controllable through IoT Hub and it reports data there. We can control our device through simple command line application but it is not enough for us. In this post we start building Universal Windows Application that helps us monitor temperatures. In this post we focus on mobile application.
Read moreWe are eager to try out our beer cooling solution and we want to see it in action. We want to visualize our data and keep eye on temperature of cooling beer. Before doing anything more complex like building web or mobile app we make a quick shortcut and bring our data to web, desktop and mobile. This post is about Power BI in action.
Read moreWhen cooling beer we want to store history of temperatures for two reasons. First, it gives us valuable history data for next cooling sessions. As a second thing we can ask measurements when we temporarily lost connection with IoT Hub. In this posting we make some analyzis and then build up database for our beer cooling solution.
Read moreAs we have now fully functioning thermal solution running on Windows 10 IoT Core it’s time to focus to other components of our beer freezing solution. Our solution measures and calculates metrics of cooling beer but it doesn’t report this data anywhere. In this blog post we will set up Azure IoT Hub for our solution so it starts reporting measurements to Microsoft Azure.
Read moreIn my last beer IoT post we measured out cooling rate of beer. In this post we try to estimate how long it takes for beer to start freezing. It’s actually simple calculation and we add it to our beer IoT background service before we focus on data reporting and persisting questions.

Some posts about my IoT solution that helps me to cool eisbock beer to freezing needed mathematical equations. I know I can use poorly supported MathML or bitmap images but both of these solutions come with problems. I tried to find some better solution and found MathJax.
Read moreMy previous beer IoT post introduced how to measure cooling rate of beer. As I introduced the first calculation there I implemented it in code the way it just works and gets calculations done. Now it’s time to focus on the implementation and make some small improvements that clean up code and improve technical design.
Read moreAs thermal sensors are connected and we have code to read temperatures it’s time to get serious and start real work on supporting the cooling process of eisbock. We start with measuring temperatures, calculating cooling rate and estimating how long it takes for beer to freeze. This post focuses on cooling rate.
Read moreMy previous blog post “Measuring temperature with Windows 10 IoT Core and Raspberry Pi” introduced you my simple solution for measuring temperatures. In this blog post we go step further and make some modifications to solution architecture so we don’t have to keep sensors connected all the time and as a result we can also emulate temperatures and situations that are not easy to produce in home or office.
Read moreI have RaspberryPi 2 with Windows 10 IoT Core and I plan to use it for some brewing activities. In this blog post I introduce how to measure temperature with RaspberryPi using DS18B20 thermal sensors. This post is also example about how easy it is to get started with your IoT stuff using Microsoft tooling.
Read moreAzure Search is new cloud service by Microsoft. I played with this service a little bit and now it is my favorite toy. In this post I give a quick overview of Azure Search and tell you what it is and what it is not. Also I provide some advice about what tools you need and how to get rid of some problems I faced when using service on CoreCLR.

ASASP.NET Core has dependcy injection available at framework level and ASP.NET Core is heavy user of it. Most of things surrounding controllers, views and other MVC components are implemented as services that web applications consume. This post is intensive overview of dependency injection in ASP.NET Core.

With ASP.NET 5 we don’t have current bundling and minification system available. It’s replaced by new one that is based on Gulp. Default web application shows how to minify simple and safe files. But if you have some more complex design with CSS files referring to images then you are on your own. This post shows you how to solve a problem.
Read moreOne mystery in ASP.NET 5 that people are asking me about are ASP.NET 5 console applications. We have web applications running on some web server – what is the point of new type of command-line applications that refer by name to web framework? Here’s my explanation.
Read moreI have project where I need to output some reports as CSV-files. I found a good library called CsvHelper from NuGet and it works perfect for me. After some playing with it I was able to generate CSV-files that were shown correctly in Excel. Here is some sample code and also extensions that make it easier to work with DataTables.
Read moreAlthough ASP.NET MVC has been here for years the discussion about fat and thin controllers continues. There are guys who have strong faith in fat controllers and guys who believe more in thin controllers. Having seen both types of controllers I wrote this post to share my experiences with you.
