I announced almost exactly one year ago that I was rewriting the Encodo C# Handbook. The original was published almost exactly nine years ago. There were a few more releases as well as a few unpublished chapters.
I finally finished a version that I think I can once again recommend to my employees at Encodo. The major changes are:
Here’s the introduction:

.NET Standard 2.0 is finally publicly available as a preview release. I couldn’t help myself and took a crack at converting parts of Quino to .NET Standard just to see where we stand. To keep me honest, I did all of my investigations on my MacBook Pro in MacOS.
I installed Visual Studio for Mac, the latest JetBrains Rider EAP and .NET Standard 2.0-preview1. I already had Visual Studio Code with the C#/OmniSharp extensions installed. Everything installed easily and quickly and I was up-and-running in no time.
Armed with 3 IDEs and a powerful command line, I waded into the task.
Quino is an almost decade-old .NET Framework solution that has seen continuous development and improvement. It’s quite modern and well-modularized, but we still ran into considerable trouble when experimenting with .NET Core 1.1 almost a year ago. At the time, we dropped our attempts to work with .NET Core, but were encouraged when Microsoft shifted gears from... [More]
I encountered some curious behavior while writing a service-locator interface (_protocol_) in Swift. I’ve reproduced the issue in a stripped-down playground and am almost certain I’ve found a bug in the Swift 3.0.1 compiler included in XCode 8.2.1.
We’ll start off with a very basic example, shown below.
The example above shows a very simple function, generic in its single parameter with a required argument label
a:. As expected, the compiler determines the generic type
T to be
I’m not a big fan of argument labels for such simple functions, so I like to use the
_ to free the caller from writing the label, as shown below.
As you can see, the result of calling the function is unchanged.
Let’s try calling the function with some other combinations of parameters and see what happens.
If you’re coming from another programming language, it might be quite surprising that the Swift compiler happily compiles every single one... [More]

For over a year, I’ve been writing articles about various parts of Quino. A customer asked if I could collect those links into a coherent table of contents, to make it easier to use as a reference.
Check out two new talks on our web site:
Microsoft recently published a long blog article Introducing .NET Standard. The author Immo Landwerth appeared on a weekly videocast called The week in .NET to discuss and elaborate. I distilled all of this information into a presentation for Encodo’s programmers and published it to our web site, TechTalk: .NET Standard 2.0. I hope it helps!
The summary below describes major new features, items of note and breaking changes. The full list of issues is also available for those with access to the Encodo issue tracker.
This release is a “bridge” release that has the entire new Metadata API as well as the older version, which is marked as obsolete. It is intended that projects upgrade to this version only temporarily in order to more easily migrate to the 4.0 Metadata API. At that point, projects should immediately upgrade to Quino 4.0, from which all obsolete methods have been removed. Once 4.0 is available, there will be no more bug-fix releases for this release.

From a customer, we got the request to apply a visual style guide (VSG) to a Bootstrap-based application. Since we do have a lot of experience with applying style guides on web applications and styling in general, we accepted the job and started to evaluate the details.
The most recent stable version of Bootstrap is 3.3.6. However, when you go to the Bootstrap website, there is an announcement that Bootstrap 4 “is coming”. The current state of Bootstrap 4 is alpha and the last blog post is from December 2015 which is almost half a year ago. It also is not clear, when version 4 finally will be available and stable and so we had to use the old Bootstrap 3 for this project.
But even here, there is some obscurity going on: Bootstrap was initially developed with LESS but for some reason they decided to switch to SASS. Even if we prefer to use LESS at Encodo, we decided to use SASS for this project to be able to upgrade to Bootstrap 4 more easily when... [More]
Encodo has long been a two-space indent shop. Section 4.1 of the Encodo C# Handbook writes that “[a]n indent is two spaces; it is never a tab.”, even though “[t]he official C# standard […] is four spaces.” and that, should you have a problem with that, you should “deal with it.”
Although we use our own standards by default, we use a customer’s standards if they’ve defined their own. A large part of our coding is now done with four spaces. Some of us have gotten so accustomed to this that four spaces started looking better than two. That, combined with recent publicity for the topic, led me to ask the developers at Encodo what they thought.
We discussed ABD in a recent article ABD: Refactoring and refining an API. To cite from that article,
“[…] the most important part of code is to think about how you’re writing it and what you’re building. You shouldn’t write a single line without thinking of the myriad ways in which it must fit into existing code and the established patterns and practices.”
With that in mind, I saw another teaching opportunity this week and wrote up my experience designing an improvement to an existing API.
Before we write any code, we should know what we’re doing.
