Entity Framework makes it possible to execute scalar-valued functions when querying models. However, it’s not very intuitive to get this working, and it’s not directly possible to map the returned scalar value to an instance of your model. Odd, right?

Developing and Deploying .NET Applications on Linux (Part 1)
posted on September 7, 2015 by long2know in ASP.NET, Microsoft
As a web developer primarily utilizing .NET for backend server development, and as one who uses Linux for my own hosting environments, Microsoft’s efforts to make .NET 5 cross platform are welcome. Over the Labor Day weekend, I spent a bit of time seeing how I could leverage this to host .NET web applications myself. While I mention Mint Linux, specifically, this guide should apply to any Debian/Ubuntu derivatives.
IE11 rounded-corner bug
posted on September 4, 2015 by long2know in css, Web
Last month, I made a blog post detailing how to use CSS arrows as a progress indicator. I really like this and use it whenever I’m asked to create a wizard-like interface.
However, I discovered, after finally updating from IE9 to IE11 that there is a specific IE11 bug that reared its ugly head.
AngularJS reusable table directive
posted on September 3, 2015 by long2know in angularjs, codepen, JavaScript, plunker, Web
Writing web-based line of business applications entails creating a lot of views with tables.
There are many jQuery table plugins and Angular directives for rendering tables, but I created my own for, primarily, read only tables.
Weird OWIN Middleware Behavior
posted on September 3, 2015 by long2know in ASP.NET, Microsoft, OWIN, Security
Previously, I blogged about writing your own handler to hook into the OWIN middleware pipeline. I’ve been using the handler I described in that post for quite some time now.
However, after a bit of QA, I noticed at least one strange behavior.
Updating SQL Aggregate Columns
posted on September 3, 2015 by long2know in Database
Often in dealing with data in a normalized database, aggregate data is stored on within a parent table. This is done to simplify display of data and general querying.
However, it can cause data to become out of sync if the child tables are edited.
Angular Toast Notification Service
posted on August 24, 2015 by long2know in angular, codepen, jQuery, plunker
I’ve been using the jQuery plug-in “toastr” for quite some time as a basic growl/notification system. As a basic service, it’s dead simple to wire up. If you don’t know what this plug-in does, check out the demo of it.
But, I found that I needed more interactivity than basic hide/show messaging scenarios. I needed to be able to render full templates inside of the toast messages to allow for interactivity bound to DOM events.
Entity Framework Transactions
posted on August 18, 2015 by long2know in Database, Entity Framework
Entity Framework uses the Unit of Work pattern. It’s useful, but it doesn’t quite cover all of the bases.
In using a repository pattern, I rely on EF to simply deal with UOW and have not had occasion to go beyond UOW. However, on a recent project, I found that I needed to manage my own transactions.
Angular Property State Watcher and Setter Directive
posted on August 17, 2015 by long2know in angular, codepen, JavaScript, plunker
Ok, I couldn’t think of a good title for this post. But, I found this concept to be pretty interesting.
Basically, I wanted a directive that would allow me to watch AND set a property as if it were a state changing bool. This needs a bit more explaining, I’m sure.
JavaScript and Web sandboxes
posted on August 10, 2015 by long2know in JavaScript, Web
In case you hadn’t noticed, I use JsFiddle for most of JavaScript demos and to embed samples into my blog. I like JsFiddle, but it does have a few annoyances.
As a result, I started looking at some alternates.
