On the importance of Naming in Software

One of the most important things in a good project is naming. You can’t deny it – Good names of Modules, Classes, Methods and Variables can make the difference between a code that’s a joy to read and obscure text. Some names are so bad that every time I see them I get a little jolt of annoyance bordering pain. I mean, I worked so hard to build this beautiful piece of code, this piece of art really and it’s now completely ruined by this… Name.

Prevent (some) MEF loading crashes with a Roslyn Analyzer

If you’re working on a MEF (Managed Extensibility Framework) application, you’re probably familiar with its ups and down. On the one hand, MEF is a powerful plugin system, that’s a pleasure to work with once you know it well. On the other hand, we all encountered strange failures that originated with MEF. Such failures are a nightmare to debug and identify. There are several reasons why a MEF failure might happen.

Creating a Roslyn Analyzer that wraps code in a try/catch statement

I recently had to create a Roslyn Analyzer that envelopes code in a try/catch statement. This reasoning was to prevent loading errors in any exported MEF component. Here’s the analyzer in action: The analyzer does the following: Adds a Diagnostic that finds a MEF ImportingConstructor with content that’s not entirely wrapped in a try/catch statement. Provides a Code Fix to handle the problem. The Code Fix will: Add a try/catch statement around the entire content Add ErrorNotificationLogger.

C# Features: Innovations or Imitations? – Part 2

In part 1, we saw how C# has evolved from its inception in 2000 to the C# 3.0 release in 2008. C# did not introduce a revolutionary syntax or even revolutionary features. Instead, C# imitated most of its features from C++, Java, Scala, and several other languages. As is the Microsoft way, C# imitated many things but did it better than original. The most outstanding example of that is Generics. Even though Generics existed in Java, C#’s implementation is considerably better ([1]).

C# Features: Innovations or Imitations? - Part 1

Around the year 2000, Microsoft developed the C# language (led by Anders Hejlsberg). This language, along with the .NET framework had a significant strategic purpose. Microsoft would create a better language tied to Windows, driving customers to the Windows ecosystem and Microsoft products. Perhaps this was part of the notorious Embrace, extend, and extinguish Microsoft strategy (now in the past). This development came in response to Java, which has gained enormous popularity by then.

Where did the Microsoft Tech Stack disappear?

Did you hear about stackshare? It’s a pretty neat website that I recently discovered. The idea is that you can search for any tech company, and see their technology stack. For example, here is Airbnb’s: So the first interesting thing that came to mind was checking out what the most successful startups are using. I used this list of “successful startups”, in addition to angel.co startup database. After looking at about 100 startups, I ended up with data from 23.

Displaying any .NET object in a WPF TreeView

I recently encountered an interesting challenge: How to display a .NET object’s properties in an expandable tree view? This is something we constantly use inside the Visual Studio debugger: The debugger’s data tip control is exactly what I needed. An input would be any .NET object, and the result should be a tree view displaying the object’s properties and fields. I figured there would be an easy solution I can google and copy-paste, spending no more than 10 minutes on the whole thing.

How to resolve .NET reference and NuGet package version conflicts

In the modern world, we are dependent on dozens of libraries. These in turn, depend on dozens more and we end up with hundreds or thousands of dependencies. So now the problem arises for a single application. What to do when several of its projects depend on different version of the same assembly?
