5 Years of Merge Conflict

It feels like just yesterday that Frank [https://twitter.com/praeclarum]and I were sitting at a bar in Redmond enjoying a nice craft cocktail and talking about the best way to store settings in shared preferences. After chatting with someone for 2 hours about isolated storage how could you not become best friends and start a podcast [https://montemagno.com/so-we-started-a-podcast-merge-conflict/], record 266 episodes, and have such amazing listeners that they have downloaded our podcasts over 1.…

Setting Up an M1 Mac for Xamarin Development

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 new generation of machines marks a pivotal transition for macOS devices moving to ARM64…

Code Generation from XAML in Visual Studio is Mind-blowing Awesome

The more and IDE or code editor can do for you the better I say. Visual Studio has been crushing it with new refactorings, IntelliSense, and IntelliCode [https://visualstudio.microsoft.com/services/intellicode/], one of my favorite features ever. One thing that I have always been hoping for as a XAML developer is deeper connectivity between the XAML and the View-Model. We have seen increased IntelliSense in this area, but with the release of Visual Studio 2019 v16.9 [https://devblogs.microsoft.c…

Cross-Platform In-App Purchases for Xamarin.Mac Apps!

This week, one of my best friends Frank Krueger released his brilliant app iCircuit 3D [https://apps.apple.com/us/app/icircuit-3d/id1539977373] for macOS (he also wrote an awesome blog [https://praeclarum.org/2021/02/08/tech-of-icircuit3d.html] 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 [https://gi…

How-to Integrate Helpful Support Emails in Mobile Apps with Insightful Data & Logs

In the mad rush to finish my most recent app, My Cadence [https://montemagno.com/introducing-my-cadence-for-ios-a-simple-cadence-sensor-display/], I forgot to integrate an essential feature. A feature that enables my users to easily get a hold of me to report issues or request features, which is of course email support. Both Google Play and the App Store enable you to supply a support website and email, however this is a very lack luster experience for both you and your users. For your users the…

Asking for app reviews really works! It just takes 1 line of code!

Last week I launched a new app called My Cadence [https://mycadence.app] for both iOS [https://montemagno.com/introducing-my-cadence-for-ios-a-simple-cadence-sensor-display/] and Android [https://montemagno.com/my-cadence-now-available-on-android/].

Porting My Cadence to Android in 1 Day!

It seems like it was just yesterday that I was writing up a blog post on how I was launching My Cadence for iOS [https://montemagno.com/introducing-my-cadence-for-ios-a-simple-cadence-sensor-display/] and then blogging about how I wrote and shipped the app [https://montemagno.com/building-testing-shipping-my-cadence-for-ios-in-less-than-a-week/] in under a week. Well, it wasn't yesterday, but it was just 5 days ago! After I shipped the iOS version, I was watching some HGTV on Hulu and thought…
