Saving time and resources it is a fundamental part of each TSQL development, in this short article I would like to explain a simple trick with APPLY operator.The requirement can sound exotic but is...

  4. Introduction to Google ARCore Development

    In the past couple of years, if not more, the technology of virtual, augmented and, lately, mixed realities have taken a huge leap forward both for consumers as well as enterprise. Initially augmented reality (AR) almost entirely consisted of overlaying data on the real world, triggered by a shape, a logo, a QR code, or something else that could be easily recognised. Most of all it was very similar to a heads up display. Not really interacting with the real world, not really being part of your reality.
  5. Operation Not Legal in the Current State - Debugging ASP.NET Core Web Applications

    The other evening I was playing around with an ASP.NET Core application. When I started debugging it, I immediately saw an error message pop up that said It was a bit of a head scratcher, so I decided to restart the debug session and see if the problem resolved itself. This didn't help and I saw the same error again.I also saw that my Chrome browser had started up, but it wasn't showing my web page. It was stuck on a notification page telling me that JavaScript debugging is now enabled in Visual...

  8. Contributing to .NET for Dummies

    Over the past few months in the little spare time that I have, I’ve managed to submit a handful of pull requests to various .NET-related repositories (e.g. coreclr, corefx, docs, etc.) and incredibly, they were accepted.Now, for some, this may not seem like a big deal. But it felt like a pretty big one to me so I thought I would take some time to elaborate on the process itself, share my experience, and hopefully dispel a few myths or misconceptions that you might have that may be holding you back...
  9. Extending Tag Helpers in ASP.NET Core

    A few days ago, I was answering questions on Stack Overflow when I came across one that I thought might be relevant to share with others that might have a similar issue. The issue itself revolved around Tag Helpers, and in particular, getting data attributes found on models to properly generate the appropriate attributes when rendered.This post will introduce how to easily extend an existing tag helper for a common use-case. It will primarily focus around the use of the Input Tag Helper, the [MaxLength]...
  10. The Path is Null and Full of Squiggles

    I've been using Visual Studio 2017 since the earliest bits were available and I can confidently say, I'm a fan and highly recommend you give it a shot if you get a chance.With that being said, sometimes new features can cause things to blow up and this post is going to be discussing one of those such features, namely Lightweight Solution Load.Recently, I opened up a decently sized solution (~9 projects) and everything seemed in order. All of my dependencies were there, with no warning signs to be...
