The Learning Blazor title book cover

In June 2021, I set out on a journey to write a book in the middle of a global pandemic. I had no idea what I was doing (all things considered, I still don’t know what I’m doing). But I do know that I truly enjoy helping others. I hope you enjoy the book as much as I enjoyed writing it. Amazon Preview Foreword by Steve Sanderson Web development has been a dominating feature of the software industry for over 20 years and is likely to remain so for many years to come.

The Blazorators logo

Blazorators Blazorators is a C# source generator that creates fully functioning Blazor JavaScript interop code, targeting either the IJSInProcessRuntime or IJSRuntime types. All of this code relies on the output of one of my side projects named blazorators. While writing my O’Reilly “Learning Blazor: Build Single-Page Apps with WebAssembly and C#” book, I discovered an impactful way to use both TypeScript type declarations from common JavaScript APIs and C# source generators to generate the JavaScript interop code.

Intro With more than 40 million active users, GitHub is by far the largest source code hosting platform in the world. It’s an open source developers dream, and ecosystem and developer community unlike any other. And with all these users and such profound openness, there’s bound to be frustration from time to time. In this post we will explore an Azure Function written with ASP.NET Core 3.0 and C# 8.0. It has been designed to handle a GitHub webhook for issues and pull requests.

Background Most of us are all “slackers”, meaning we truly do spend a significant amount of time using Slack. Slack is a collaboration hub for work, no matter what work you do. It’s a place where conversations happen, decisions are made, and information is always at your fingertips. www.slack.com It’s wildly popular in the Developer Community! In fact, almost to a fault…people are constantly sharing their “slack fatigue”. I am personally a part of roughly twenty slack workspaces.

I’m proud to share that this post is part of the C# Advent Calendar and it’s my second year contributing to it! I encourage you to check out all the others here . Developers Are Lazy In the world of web development it is hard to escape certain tools that we are forced to rely on. As developers we’re innately lazy and it is safe to say that perhaps we don’t really care enough to look into other tooling options.

Every time a developer encounters a new technology it’s in our nature to explore it. This is the case with WebAssembly, and Microsoft’s vision of the world in Blazor. Blazor is single page application framework that sits atop of WebAssembly, but it’s still considered an experiment. I had the chance to interview Steve Sanderson about WebAssembly and Blazor – I shared . Now, I’d like to explore Blazor with you a bit more.

Inspiration I recently returned from Charleston, South Carolina – where I spoke at SyntaxCon. The event was very professionally organized and gave me inspiration for Cream City Code. In the main hall, they had a HALO by Simple Booth . It serves as a photo booth with a conference-specific backdrop – which is perfect for sharing the conference experience. I looked into purchasing one but was encouraged to simply write my own… so I did and this blog will detail that process.

Intro I am returning home from a long trip in Serbia for IT Konekt . This was literally a trip of a lifetime and I could not be more grateful for such an amazing opportunity. Serbia has such an incredible culture and powerful history. I have been overwhelmed by the care and attention to detail from the organizers of IT Konekt. This was my first time ever leaving the United States of America and I didn’t know what to expect.

Intro As a developer, I can say that developers are lazy - at least I know and acknowledge that I am. If I’m tasked with something even the slightest bit repetitious I’ll script it out, or find a way to automate it. Likewise, if I fall into a habit of forgetting something important - I’ll figure out a way to not forget. Especially when it comes to securing an application.
