I have gone all in on Arm devices! My main MAC machine is a Mac Book Air M1 and now my main driver at work is a Windows Dev Kit 2023 (aka Project Volterra). One tricky thing for developers is getting all the software we use to work properly on Arm. Things have come a long way since the original release of Arm devices for Mac and Windows. I have a full setup guide for my M1 for Xamarin and now .NET MAUI development, …

You know I love talking about in app purchases and subscriptions. Due to my InAppBilling library I get all the "fun" updates when Apple or Google force developers to make changes to stay compliant. Upcoming is a nice large change from Google to push Android developers to use Billing v4 (which my library does!) and another is that we must now give users a way to easily manage and cancel their subscriptions. …

Over the years I have created several apps that I am super proud of, and for the most part, I have always put them out for free onto the app stores. More recently I have been experimenting with different monetization strategies for the apps so users can unlock features or just leave a tip. For the longest time I kept things simple with a "non-consumable" one-time purchase. The strategy is straight forward, …

Android Emulators have been a pain in everyone's side for pretty much ever. Intel HAXM is great, but limited to Intel, then there were custom emulators like Xamarin Android Player and Genymotion, but required additional installs, and finally Hyper-V support, which brought with it AMD support, and side by side Docker support as well. But now, Windows 11 is here and so is a brand new Insiders Preview that brings with …

As an app developer it is hard enough to create your app, test your app, prep the app store listings, and then get your app approved. The last thing you want to think about is how fast or slow to roll out your app and updates to users. For the past 10 years all I have ever done was just release the app to everyone all at once, and for a long time this all that was available to us. However, now there are options for …

One issue that sometimes comes up in app development is keeping your app alive and running during long running processes. In my case with My Stream Timer, when the user starts a timer, it needs to keep running no matter what. My first solution was to simply turn on Screen Saver mode. var appDelegate = ((AppDelegate)NSApplication.SharedApplication.Delegate); appDelegate.MainWindow.Level = NSWindowLevel.ScreenSaver; …

Who just upgraded their MacBook after 8 years?!?! This guy!!! Let's set it up for mobile development with Xamarin for iOS & Android development in C#. That is right, I finally decided to go all in on an M1 MacBook Air (8-Core GPU, 512GB SSD, 16GB RAM) thanks to the $500 "credit" from participating in the DTK program. Not only was it time for an upgrade since my machine was 8 years old, but also because …

This week, one of my best friends Frank Krueger released his brilliant app iCircuit 3D for macOS (he also wrote an awesome blog on how it was made). While I know that catalyst support for Xamarin (and .NET MAUI) is coming soon, I still think there are great opportunities to monetize macOS apps written in C# today (see iCircuit 3D!). I released my In-App Billing Plugin a few years ago for iOS, Android, and UWP apps …
