There are two key differences compared to ASP.NET: To get started, add an appsettings.json file in your shared project. Make sure you set it’s Build Action to Embeded Resource. Add some keys + value in the file that we can use for testing. For example: Next, we need to get hold of the resource stream….
In less than 5 minutes. First step is to create your Xamarin Forms projects – start with a blank shell app – and add an additional blank ASP.NET Core project to the solution – we will use it to host our SignalR backend. Once the projects are setup, we begin by implementing the ChatHub which…
When dealing with mobile clients, it’s not always easy to get them on the same network as your development machine and even when you do, localhost will have a different meaning so you need to use IPs and change bindings and disable SSL or trust self-signed certificates, in short it’s a pain. Say hello to…
Your app’s startup time matters because it’s the first impression that the user gets to make about it’s performance. It doesn’t matter what you promise me if it takes 10 seconds to load the app each time I try and use it. I might even uninstall it thinking it doesn’t actually work. And with Xamarin…
Until recently NativeAds were in a closed beta and only certain developers had access to the ad format, but now, it’s available to everyone. Here’s how you can go about adding one to you Android Xamarin Forms app using a custom renderer. Step 1: Create a view to act as a placeholder for the ad…
While developing Xamarin Forms applications you will often find yourself in a situation where you need to set different values for a certain property depending on the operating system. OnPlatform allows you to do just that and can be used both from C# code and XAML. Let’s look at a few examples. For this article,…
I’ve started playing with animations in Xamarin Forms only recently and created a cool background animation for one of my apps (Charades for Dota 2) which I thought I would share. So without any extra introduction, this is the final result: The GIF is a bit jittery but that’s just because by PC can’t handle…
There’s a couple of new things coming with this new version of Xamarin Forms, and one of them is Cascading StyleSheets (CSS). Yup, that’s right, CSS in XAML. Not sure yet how useful it will be and how adopted it will become – as quite a few features are still missing but I’m guessing it…
So far we’ve been displaying ads only on Android and iOS through AdMob and our AdMob renderer. Google dropped support for Windows Phone altogether and never bothered with UWP so AdMob is not a choice in this particular situation. Fortunately, Microsoft is also in the advertising business and they’ve now nicely integrated everything in the…
Upgrading between major versions of Xamarin tends to break stuff and lead to projects no longer building due to weird errors. In their innocence, most devs will take these errors for real, try to understand them, to fix them and when they fail, they will Google them; when most of the times, the fix is…
Right, so you are one of those guys targeting UWP with their Xamarin Forms app… aand you want to use the new Acrylic brush to make you application stand out. Say no more. We won’t be using any 3rd party library/package to do this and we’ll be working in the platform specific project; so open…
In one of my previous posts on How To: Add AdMob to your Xamarin Forms app I was giving a piece of code that looked like this: That will work perfectly with Banner ads but it’s going to fail if you choose to use a Smart Banner. For a Smart Banner, the sizing is a…
