Colored Map Markers on Xamarin iOS and Android

I was getting ready for my next Tech Summit presentation and wanted to spice up my Maps for iOS and Android. I didn’t want to create any custom marker images or anything like that, but just wanted a little color flare on it. I knew there had to be an API out there to do it in each of the native frameworks and of course there was, so here is the quick and easy solution. (If you need this for Xamarin.Forms this would …

Cleaning Up Space on Your Xamarin Development Machine

Today, I officially uninstall Visual Studio 2015 and upgrade to Visual Studio 2017!! Whenever I do a major upgrade I usually re-format my machine and get a fresh install, but this time I decided not to and just uninstall and clean up my machine as best as I can. While VS 2015 for sure installs tons of stuff all over the place and I can manually uninstall things, I figured it was a good time to help developers clean …

Setting up Visual Studio 2017 for Xamarin Development

Visual Studio 2017 was just released yesterday, and it is awesome! You can re-live all the keynote and demo deep dives on Channel 9. There are tons of new features and a huge revamp to installation but things to me still aren’t absolutely perfect in the setup of how I like to develop. So in the spirit of my Cycle 8 and Cycle 9 installation guides I am proud to bring you the ultimate VS 2017 Setup Guide for Xamarin!

Version Bumping iOS & Android apps in Azure DevOps (VSTS)

I love Continuous Integration and Deployment for mobile applications and have given several talks on it in the past. It streamlines your entire development process and makes it drop dead simple to simply commit code and have everything you don’t want to do manually be taken care of for you. This means build, test, bump versions, and ship off to testers with integrations like HockeyApp. Notice I mention “bump …

Xamarin.Forms Android Selected & Unselected Tab Colors

I get a lot of questions about Xamarin.Forms. One of my most popular blogs was about spicing up iOS tabs with selected and unselected tab colors, and since that day developers have been asking about Android. Well, to be honest I was always against adding icons to material tabs in Android, but developers want to do it, so here is how you can, with a Custom Renderer for a Tabbed Page. Here is what it will look like at …

Gaming for a Cause #Play4PP

This blog is not about coding at all and is more on the personal side of things, which I actually don’t write about too often. So if that isn’t your thing and you just came for code then feel free to scroll past. Or, if you don’t want to read this entire thing: TLDR; On March 4th I am participating in the Play for Planned Parenthood 24 Hour Game marathon and asking for your help by donating a few $$ to my team to …
