It's been a little over a year since the last FluentLayout update, so it seemed like a good time to get some little improvements in. I also definitely want to give a shout out to Diego Ponce de León for prompting some of these changes and helping brainstorm some things! If you're using FluentLayout, I'd definitely love to hear your input on improvements you'd like to see, shortcomings, etc. There's a lot more we can do…

Earlier this week we found ourselves looking into a strange databinding problem, where things were working as expected on devices but not in the simulator. Differences between simulators and devices is certainly not uncommon, but I'm not sure I can recall a time where it was on the device that things were binding correctly, and the simulator that was showing problems.

I've found it very difficult (or impossible) to properly achieve the types of fine-grained navigation control I want in my apps by using activities for all my views, which…

In my last presenter post I showed how you can use presentation hints to tell the presenter to clear the view stack prior to showing the next view. That is probably the most common custom navigation pattern I've seen used in MvvmCross apps, but I also wanted to note another similar pattern I've used as well. When I'm mapping out the navigation paths through my apps, I try to be very conscious of the state of…
