Configuring Hangfire’s BackGround Method for .NET Core Applications

Bernardo Leite .NET, .NET Core, C#, Tutorial Leave a Comment

In this article, we will go over how to install the Hangfire NuGet package within the NuGet Package Manager in Visual Studio. Then, we’ll walk through how to configure it within the .NET Core framework using Service Fabric. Lastly, we’ll learn how to use the BackgroundJob.Enqueue method in order to schedule a background task to be performed and at the same time not disturb the flow of your code.

C# On The Client Side With Blazor

Clayton Terry .NET, CSS & HTML, Development Technologies Leave a Comment

With the introduction of .Net Core 3.0, Microsoft has built its own web UI framework.

Introducing Blazor: Microsoft’s fully C# client-side framework. With the help of its Razor platform, Microsoft is attempting to put its hat in the ring with the likes of Angular, React, and Vue.

Blazor allows developers to fully design and execute web pages purely with C# — it is meant to eliminate the need for JavaScript. The goal is also to hopefully limit the number of vulnerabilities found in front-end UI work.

In this post, we give an introduction to Blazor and a quick tutorial for getting started.

.NET Memory Management with dotMemory

Jason Schmidtlein .NET, .NET Core, Development Technologies 2 Comments

Given the maturity of the .NET Framework and the automated nature of its memory management, many developers are guilty of glossing over (or even outright ignoring) whether their code is optimal in terms of CPU and memory usage. Personally, I have caught myself making sure my code is maintainable, testable, and extendable while forgetting to consider memory management in terms of nonfunctional aspects.

While the .NET runtime does a great job and memory corruption is extremely rare, we should still be concerned with memory management, particularly in large-scale .NET base applications.

This concern isn’t limited to on-premise applications. It’s easy to forget about memory usage with cloud computing. Azure Functions and AWS Lambda have billing structures based upon the average memory size per second of function execution. The direct correlation between memory usage and cost couldn’t be more transparent.

Fortunately, there are many great tools to help profile and analyze your memory footprint. JetBrains has a fantastic tool called dotMemory which makes it easy to profile processes, auto detect issues, perform deep analysis, and determine traffic. dotMemory can be installed as either a stand-alone tool or as a part of the ReSharper package integrated into Visual Studio.

In this post, we’ll show how to use dotMemory to generate a memory profile and analyze a memory leak in a .NET Core application.

Create your own web bots in .NET with CEFSharp!

Matt Cunningham .NET, JavaScript, Programming, Tutorial 5 Comments

Have you ever wanted to create an automated way to load, manipulate, and then act upon a web page?

Using CEFSharp (and some strategic JavaScript), you can create headless (no GUI) interfaces of Chrome’s parent browser, Chromium, and then instruct them to do pretty much anything a web browser can do.

This is a tutorial about using CEFSharp to accomplish some basic web functions with simple examples. We’ll create three automated bots that can simulate user web interaction and programmatically react to browser events using CEF and the CEFSharp library. You can follow along by copying the code provided or by downloading…
