Finally! You can now use bash and almost any linux program on your Windows 10 machine. You do not need cygwin or MinGW anymore! This will give you opportunity to use rich variety of tools available only on linux. For example wrk - a great HTTP benchmarking tool which I plan to use for a new ASP.NET Core 1.1 benchmark. Linux's user space available from Windows 10 version 1607. But it's disabled by default. To enable it you should: Go to Settings -> Updates & security -> for developers a...

Here is an example of the nginx server block (Virtual Hosts) which you can use to host multiple web sites on the same server. Just replace example.com with your own domain name. Do not forget to create all required folders and sent right permissions.

.NET Core framework provides one very useful feature - Self-contained application. You don't need to install any .net runtime on your computer, you can just copy your application to the target host and run it. Furthermore, you can run it on any platform (Windows, Linux, OSX)! When you create a self-contained application, after publishing, you will see the whole .net runtime next to your application. There are some advantages: You do not need to have installed .NET Core on a target machine You ca...

If you are using Selenium WebDriver as a web crawler and thinking that it's too slow, welcome inside! In this article, we will see how to make page parsing time around 50 times faster. As an example, I will parse comments from another article from this blog. I will first parse it using default WebDriver API (FindElement... methods) and then will compare it to CsQuery Here is WebDriver parsing code: var driver = new ChromeDriver(); driver.Navigate().GoToUrl("/2014/07/fixed-setup-was-unable-t...

If you want to run C# application (mono) with Selenium ChomeDriver on Ubuntu Server 16.04 in headless mode, you definitely should read this article. We will use Xvfb as X server, this will let us emulate "headless" mode because Xvfb performs all graphical operations in memory without showing any screen output.

Unity3d 5.3.0 introduced JsonUtility class which will help you with JSON serialization and deserialization. But this class has some limitation, and one of them: "You cannot serialize\deserialize System.Guid type" That's a pity, especially if you're using System.Guid in your DTO objects. But, there are solutions: You can change a data type, for example, use System.String or System.UInt32 instead of System.Guid. But if you have a lot of code which uses your DTO objects it might be painful to refac...

There is no more public Configuration() { AutomaticMigrationsEnabled = false; } in Entity Framework Core 1.0 (formerly  EF 7.0) Now you can use extension Migrate method during database initialization. For example, you have custom DBInitializer class: public class DBInitialization { public static void Initialize() { using (var context = new DbContext()) { context.Database.Migrate(); // Other db initialization code. } } } There is also async version of this method. This method will apply any pendi...

At Novility, we have  found that we cannot log working time anymore. You just press "Make me happy" button and nothing :( When ZohoPeopleTimeLogger tries to make you happy it needs information about current jobs from ZOHO.

Download GitHub User will see message box with detailed description and nice instructions:

Guys from Newark element14 have sent me a nice dev board - Intel Galileo Gen2. I was curious because before, Microsoft declared that Windows 10 IoT Core will run on this board. I planned to run my previous benchmark on this board to see if it can beat Raspberry PI 2. Unfortunately, with the latest release they removed this board from the compatibility list :( But this is not a big problem because I have some plans about home automation and I can use this board in it. I have couple nRF24L01 modul...

For those who do not know, AppVeyor is Continuous Integration and Deployment service for .NET projects. It is free for open-source projects. Currently, AppVeyor supports latest DNX version (1.0.0-rc1-final) and I've recently migrated my pet project to this version. I will show you how easy it is to build and run all unit tests on CI server every time you commit to GitHub.
