Previously I wrote about several “gotchas” in the new JSON serializer that is built in to .NET Core 3.0. Another one has cropped up, but it is different enough that I thought it warranted its own post. Type Promiscuity via GIPHY Back in 2010 or something like that, Ted Neward gave a talk about JavaScript … [Read more…]
SignalR is part of the .NET Core framework that allows for real-time communication between a server and any number of clients. The traditional example is a JavaScript client that can receive updates directly from a web server asynchronously, but you can also connect to a SignalR hub with a C# client. via GIPHY HubConnectionBuilder To … [Read more…]
I was following the new .NET Core 2.2 –> 3.0 upgrade document, but when I updated my unit test project files, I accidentally set the SDK to Microsoft.NET.Sdk.Web because that’s what my ASP.NET Core 3.0 web project was. via GIPHY The unit tests still ran and worked… for the most part. One of them failed, … [Read more…]
Sometimes there’s a path in a service or application that you want to test where all it does is log something and return. You could check other things, but sometimes it is hard to check to see if something didn’t happen… and it would be a lot easier to know if something did happen, like … [Read more…]
When you’re writing an API that deals with a TCP client, you need to talk data in terms of byte arrays. via GIPHY BitConverter BitConverter is a class in the System namespace that lets you convert numerical data types (and single chars) to and from their byte[] counterparts. In order to convert to a byte[], … [Read more…]
Bit flags aren’t probably something that you think about in traditional/modern software development. You might if you are in the IoT space, but if you have the pleasure of a ton of RAM, you probably aren’t super concerned with saving space. However, recently I’ve been thinking a lot about network communication and how to minimize … [Read more…]
I’ve never really liked hexadecimal notation. The combination of letters and numbers always made my brain turn off. I mean, I understand it, but it never seemed like it made a difference or not. via GIPHY Binary Obviously, computers think in ones and zeroes. The smallest unit is typically talked about as a byte, which … [Read more…]
Previously I talked about how to set up the server side of SignalR for facilitating real-time communication. One of the parts that I don’t particularly care for in that default implementation is that the hub methods (the messages that are sent to connected clients) are identified by strings. Sure, you could create some string constants … [Read more…]
SignalR is a technology that allows you to write bi-directional communication between a server and a client. This can lead to some pretty cool interactions, such as a live-updating dashboard on a website, or the ability to communicate requests to a server without building HTTP endpoints. SignalR does a lot of heavy lifting behind the … [Read more…]
For some reason I always thought that you needed to add a third party library to make a zip file in C#, but apparently you can do it easily with an API that already exists in the framework. via GIPHY ZipArchive All you need to do is create a file and associate the file stream … [Read more…]
