In the last post I talked about streaming data back via a WebAPI. On the front end, I had a “download” button that I wanted to disable until the download is complete, so that users don’t inadvertently spam the server with download requests. When the button is clicked, an iframe is opened to the WebAPI … [Read more…]
So I built a service that collects information, say, log information, and sends it down to a client. This information is normally streamed right to a web browser via SignalR, but sometimes there is a lot of it, and scrolling through it on the web view can be quite a pain. It would be nice … [Read more…]
C# has a Stopwatch class that is pretty accurate at timing things. In fact, it uses some low-level operating system stuff to make sure to get exact timings. This means it can be more accurate than comparing two different DateTime.Now instances. via GIPHY I’ve found myself using the Stopwatch occasionally, but it always is kind … [Read more…]
Recently I had a situation where I had a class and interface to make a generic service which would do something based on whatever type is provided. (Obviously, it was not so contrived…) These would then get injected to other classes to be used as necessary: Which works fine… as long as you remember to … [Read more…]

Good intentions give way to some small overlooked issue. via GIPHY Parsing HTML There are a lot of cool utilities for parsing HTML in C#. One of the most popular one is … [Read more…]
So I was writing an inline if statement the other day… you know the ones – booleanStatement ? resultIfTrue : resultIfFalse; It was pretty simple, so I didn’t think too much about it until I ran some unit tests…. via GIPHY Here’s what my code kind of looked like: So, what would you expect the … [Read more…]
Sometimes you just need some logging to do a sanity check that things are actually working the way that you’re expecting. via GIPHY Here’s how to turn logging on in ASP.NET Core 2 for SignalR: I’ve had to look this up more than twice, and its not exactly easy to find in the Microsoft docs, … [Read more…]
XUnit has some cool stuff like Theory, which lets you write multiple test cases to run against the same test code. This lets you test multiple paths with different inputs without having to write multiple tests. This can save you a lot of time as you can cover a lot of ground with a single … [Read more…]
There are a bunch of different ways to do this, but sometimes I find myself wanting to run multiple web applications locally on different ports without fussing with configuration files, etc. And whenever I need to do this, I always have to look it up… but most of the posts out there are how to … [Read more…]
