I have seen this issue occur now and again with a Xamarin Android installation on Windows. It seems to occur after a Visual Studio update which also updates the Xamarin Android installation.

Custom Components in .NET MAUI / Xamarin Forms
When designing an application, we must often build user-interface (UI) elements which are used in more than one place. When writing code, we usually try to follow the DRY (Don’t Repeat Yourself) principle, and we should strive to do the same when working with the user-interface. In .NET MAUI/Xamarin Forms, we can build a user… Continue reading Custom Components in .NET MAUI / Xamarin Forms
Running a .NET 6 ASP.NET Application on Azure Cloud Services
I have a project where I need to migrate a large and complicated ASP.NET application running on .NET Framework to .NET 6. This migration is further complicated by the fact that the application is currently running in production using Microsoft Azure’s Cloud Services offering. This is an older form of deployment which predates the newer App Service. Unfortunately, Cloud Services does not ship with native .NET… Continue reading Running a .NET 6 ASP.NET Application on Azure Cloud Services

Using Multiple Namespaces to Increase Active Devices with Azure Notification Hubs
Introduction This is a follow up to my previous 3-post blog series on Learning Azure Notification Hubs. At the time of writing, on the free tier, there is a limit of only 500 active devices per namespace. The basic plan increases this to 200 000 devices for about $10 (USD) a month. While $10 is not… Continue reading Using Multiple Namespaces to Increase Active Devices with Azure Notification Hubs
Implementing Azure Notification Hubs – Part 3 (API Project and Testing)
The complete solution for this can be found on my GitHub account. In launchSettings.json, remove the IIS settings as well as Launch Browser, Launch Browser URL and the HTTPS URL. I prefer to run the application directly instead of through IIS and using HTTPS can sometimes cause issues while testing UWP applications. You could use HTTPS by installing and trusting the development certificate provided by ASP.NET… Continue reading Implementing Azure Notification Hubs – Part 3 (API Project and Testing)
Implementing Azure Notification Hubs – Part 2 (Shared and App Projects)
The complete solution for this can be found on my GitHub account. We will start work in the shared project as the classes we create here will be required by both the API and the Xamarin application projects. DTOs In the root directory of the project, create a folder called Dtos which will contain DTO classes that will be… Continue reading Implementing Azure Notification Hubs – Part 2 (Shared and App Projects)
Implementing Azure Notification Hubs – Part 1
Introduction Sending push notifications to devices is a requirement of most applications. Unfortunately implementing this is not as simple as you would expect. Azure offers a service called Notification Hubs which makes implementing this feature easier, but there is still a fair bit of manual work involved. Azure Notification Hubs offers a free tier that… Continue reading Implementing Azure Notification Hubs – Part 1
Using Fiddler to inspect HTTP traffic

According to the documentation as of 2021/08/17, the following XML is required to create a template registration for Windows devices: When I used this, I got a 200 OK response from the… Continue reading Using Fiddler to inspect HTTP traffic
