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…]
Every now and again I find it necessary to set up the request body manually (as opposed to using the [FromBody] tag). In the controller you can read from the request body easily enough: via GIPHY Testing How do you test this? Normally I would just create a controller, call the method, and check the … [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…]
Autofac is a popular dependency injection library that I like to use because they’ve done a lot of legwork to get things to work nicely in .NET Core – (some DI frameworks were not happy with Microsoft’s decision to make a public abstraction for their own DI library). Modules If you have a big solution … [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…]
Imagine that you have a NuGet package containing a bunch of static strings. These fields are intended to be used instead of magic strings, making it so anything that takes a dependency on this NuGet package will all be on the same page about these unique keys. Now suppose that these keys also represent the … [Read more…]
