Although I bought refactoring book by Martin Fowler years ago it is still valid. I call it one of the timeless books about coding and I consider it as a mandatory reading specially for novice programmers who are entering the field. Of course it is also useful handbook for those already in business. This refactoring book covers and organizes most of changes we are doing to source code every day and it greatly helps us to understand the nature of those changes at crafting level.

Before applying any optimizations to our code we have to ask one question: what is the cost of improvement and is it really improvement? Compiled queries in Entity Framework 2.0 are categorized as high-availability feature but before making any decisions we need to know what is the actual win. This blog post introduces the measurements I made with simple database context to compare compiled and uncompiled queries in Entity Framework Core 2.0.

Entity Framework Core 2.0 introduces explicitly compiled queries. These are LINQ queries that are compiled in advance to be ready for execution as soon as application asks for data. This blog post demonstrates how compiled queries work and how to use them.

Microsoft Intermedia Language (MSIL) is .NET assembly language that is standardized under name Common Intermediate Language (CIL). All .NET compilers turn source code to this language. Although we hardly have a situation where we have to write intermedia language (IL) code directly it is still good to know how it works and how it is supported on Visual Studio. This blog post fills the gap and shows how to write IL code on Visual Studio.

My previous blog post introduced how to make ASP.NET Core 2 web application run on Windows 10 IoT Core. It was default web application created on Visual Studio and published as an executable. But this is not enough for IoT scenarios. When we build web application that runs on IoT board we need this application to do something. Be it displaying sensor data or controlling some hardware. This blog post shows how to make Windows 10 IoT background task talk with web application using WebSocket.
