Adding your own help functionality to Visual Studio F1 Help

Jul 22, 2019

Not long ago a participant at a course of mine asked an interesting question. They were working on a project that used a .NET API extensively and they had developed their own set of internal documentation. The requirement was simple: you know the simple help feature of Visual Studio where

Implementing the Repository pattern with direct IQueryable support

Akos Nagy

Jul 2, 2019

Lately I have written a lot of posts about the Repository and Unit of work patterns. You can check out all the software design posts about why I think they are (still) useful and how you can use the Specification pattern to improve on it. So this pattern has been

Autofac support for AutoMapper

Jun 27, 2019

I have been doing .NET development for quite a while now. Sometimes people ask me how is it possible that I still find it interesting. Well, the answer is easy: I'm super D.R.Y. If you are not familiar with the term, you should look it up, but it

The specification pattern and variance

Akos Nagy

Jun 25, 2019

In a previous post I described the specification pattern, its uses and benefits and also gave a pretty neat implementation. However, there was something that I didn't discuss: the variance aspect of the pattern. It is a very important aspect, but that post was long enough as it was — so

Supporting async LInQ evaluation on IQueryable mocks

Akos Nagy

Jun 18, 2019

IQueryable<T> is a tricky interface. Some people argue that it is actually a bad abstraction, because it is impossible to implement it. This post is not about trying to prove or disprove this point. People who say this do have a point, but I do think they

Trying the Azure SignalR service

Jun 14, 2019

Totally unexpectedly I ran into something "new" in Azure: the Azure SignalR service. It's been out there for a while, but somehow I haven't come across it (to be fair, it is now one of the better-marketed services of Azure). According to the documentation, it gives you a

Default interface implementation in C# 8

Akos Nagy

Jun 12, 2019

A while back the preview version of the last big feature of C# 8 came out: default interface implementation. To be honest, I'm not really a fan of this new option and I have been pretty busy, so I didn't really have the time to check it out, nor did

Duplex service over TCP with WCF

Akos Nagy

May 27, 2019

I was asked by one of my clients that I consult for to help with a TCP-based duplex communicaton solution using WCF. It's been a while since I have blogged about WCF (actually, it's been a while since I have used it), so I though it might make a good

Using the Specification pattern with Repository and Unit of work

Akos Nagy

May 22, 2019

The age-old question of whether you should use the Repository and Unit of work patterns comes up pretty often in my life. That's probably because I'm for and not against :) and whenever I teach or wherever I go to consult, I always tell people to use this pattern. And then

Visual Studio extension to change the C# language version of a project

Akos Nagy

May 16, 2019

One of the courses that I teach is a workshop on the new features of the new C# language versions. During the course we look at the different language features of C# 6 and the newer versions. To illustrate the different features, I often change the language version of the
