Last night I was working on a project that had some many to many database relationships. On one side of the relationship, someone decided to use zero as the default “nothing selected” sort of key. This simply doesn’t work with Entity Framework, or probably most other .NET ORMs.

Angular Event Emitters with RxJS Subscriptions and Subjects
posted on January 26, 2018 by long2know in angular, plunker
While I was working through my post regarding generically formatting Angular data within a component, another generic implementation that I needed arose. I needed a way to, in a very generic fashion, raise events from a child component to its parent. Within the context of an Angular table, this could typically coincide with a click event that needs to take action, or apply some logic, to the child’s bound data. Event Emitters in Angular readily facilitate this type of functionality.
Angular User Session Timeout
posted on December 20, 2017 by long2know in Uncategorized
A long time ago, I blogged about a service that I used in AngularJS to let the user know that their session is about to expire and that they would be logged out if they didn’t take action. I needed to recreate this functionality in Angular for my latest swath of applications.
Angular Datepicker – Exploring Bootstrap (Part 3)
posted on December 8, 2017 by long2know in angular, plunker
Since I’m using a lot of Angular Bootsrap components in my Angular apps, now seemed like a good time to revisit the classic Datepicker. The Angular Bootstrap Datepicker is relatively easy to get up and going, but I did run into a few quirks.
Angular Formatting Data
posted on November 28, 2017 by long2know in angular, plunker
A while back, I blogged about an Angular Table component that I wrote. Since that time, this component has expanded a fair bit as my application needs grow. Once such feature that I needed recently was the ability to format data dynamically.
Angular Dynamic Routes and Application Initialization
posted on November 15, 2017 by long2know in angular
As I’ve been using my latest Angular demo which is Visual Studio based increasingly in production applications, I’m finding more and more things that I have to port from the older AngularJS templates that I had put together. Today, I needed to understand and develop a means to dynamically handle routing and application configuration (initialization).
Angular Toast (Growl) Notifications
posted on November 3, 2017 by long2know in angular
In my older AngularJS applications, I used a jQuery plug-in plus AngularJS singleton “notification” service whenever I wanted to display toast/growl notifications. With the newer Angular framework, I started going down this path, but did also play around with an Angular module that provides this functionality.
Angular 5.0 released

Yesterday, Angular 5.0 was released. The Angular team provides a handy upgrade guide to help with upgrading from any previous version of Angular. Upgrading from 4.x was pretty straight-forward.
.NET Core Generic Repository Dependency Injection
posted on October 26, 2017 by long2know in Core
This morning I was updating some Data Models in a project, and noticed, based on my project scheme, that I would have to add a derived BaseRepository class. This is a side-effect of the way I’ve used Ninject for a long time and every IRepository<T> is specified to be a BaseRepository<T>. That pattern is a little annoying, and in some ways, is counter-intuitive when dealing with DI and generics.
.NET Core Factory Pattern for Multiple Mappers (AutoMapper)
posted on October 17, 2017 by long2know in ASP.NET, Core
A friend of mine asked me yesterday how one would go about having an AutoMapper configuration such that you have multiple mappings for the same object pairs. This is an interesting situation for which I didn’t have an immediate answer. But, after playing around with AutoMapper a bit, my choice was to utilize a factory to provide multiple IMapper instances.
