YADNC3JSG–Yet Another .NET Core 3.0 JSON Serializer Gotcha
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…]
Logging in a .NET Core 3 SignalR client
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…]
.NET Core 3 unit testing project sdk
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…]
.NET Core 3.0 Upgrade–New JSON Serializer Gotchas

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…]
Unit Testing bit fields
Last week I wrote about bit fields and how they can be used to easily track boolean values. Unit testing is pretty important to me, because I make mistakes a lot. By writing tests, I can have a little bit of confidence in the code that I wrote. via GIPHY Bit Fields Knowing how bit … [Read more…]
Bit Flags
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…]
SignalR Strongly-Typed Hubs
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…]
