Handling lifecycle events on iOS and MacCatalyst with .NET MAUI

I just blogged: Handling #lifecycle events on #iOS and #MacCatalyst with .NET #MAUI #dotNET #dotNETMAUI #iOSDev #macDev #programming #CSharp #mobileDev #DesktopDev

My current side project is running on iOS and MacCatalyst. Even if both of them are able to share a lot of code, there are some challenges that you should be aware of if you’re going down this route. One of these challenging areas is the handling of the lifecycle events. Read the docs first Before you continue to read this post, I recommend reading the MAUI documentation about the app lifecycle…

How to modify the border of a .NET MAUI Entry on iOS and MacCatalyst

I just blogged: How to modify the border of a #dotNET #MAUI Entry on #iOS and #MacCatalyst In this post, I will show you how to modify the #Handler to take control over the #Entry’s border by changing the underlying native control. #iOSDev

In my recent side project, TwistReader, I needed to modify the Border of an Entry to match my application’s primary color. The .NET MAUI Entry does not provide a direct way to change the color of the border, however. Luckily, it isn’t that difficult to change the color of the border, nonetheless. Modifying the mapping of the native control The .NET MAUI Entry renders to a native UITextField.…

A deeper look into menu bar handling in MacCatalyst apps with .NET MAUI

I just published a new #blog post! I am going to show you how to handle the menu bar in #MacCatalyst apps with #dotNET #MAUI in an #MVVM-friendly way. #dotNETMAUI #macOS #desktop #cssharp #programming

My current side project TimeTraverseHub has entered the stage where I need to add some global menus that are available everywhere in the app. Being a .NET MAUI app, I tried the naive approach first and followed the documentation from Microsoft. I was able to quickly add items to the application’s menu bar, but discovered the edges pretty fast. So I went out to learn more about how the menu…

2023 - yet another annual review [Editorial]

I just published my personal #review of #2023 on my #blog #Editorial

Leaving dormakaba AG The first two months of the year I spent with preparing my leaving of dormakaba AG at the end of February. As I made several templates and tools to use those templates for the interfaces we wrote, I needed to document a lot for my remaining colleagues there. Other than that, I was still investing time into my #CASBAN6 project sporadically. New role at Galliker Transport…

As we have done the work for macOS, we can turn our attention now to the Windows operating system. Spoiler: this post will be far shorter than the last one. Recap Dealing with application windows on macOS with .NET MAUI In my last post, I showed you how to support multiple windows and handle their size. I introduced you the IWindowService to handle windows in an MVVM friendly way and told you…

Dealing with application windows on macOS with .NET MAUI

I just published a blog post on how to deal with application windows on macOS with .NET MAUI #dotNET #MAUI #dotNETMAUI #csharp #macOS #MacCatalyst #programming #MVVM

As I posted already on my Mastodon feed, I recently had to deal with application windows for one of my side projects. It all started because I needed a secondary window of fixed size that can be opened with different items of the same type, providing the same options to all of them. Let’s have a look what this post will cover: Supporting multiple application windows Handling the size of…

Prepare your Mac to be a Xamarin/.NET MAUI build host without VS4MAC

I just blogged: Prepare your Mac to be a Xamarin/.NET MAUI build host without VS4MAC #VisualStudio #VS4Mac #Xamarin #XamarinForms #dotNET #dotNETMAUI #MAUI #macOS #iOS #iOSDev #IDE #Build #host

Overview You can connect to a Mac Build host from your Windows machine without Visual Studio for Mac installed. All you need is to install the right packages, which are (luckily and for the time being), available to be downloaded separately. You just need to select the right versions that match your Visual Studio installation on Windows. Install .NET Of course, the first step is to install the…

How to use the Android emulator on a macOS host for debugging in a virtual machine with Windows

I just blogged: How to use the #Android emulator on a #macOS host for debugging in a virtual machine with #Windows #adb #emulator #ssh #Parallels #VM #VirtualMachine #VS4Mac #Rider #VS2022 #VisualStudio #Debug #devlife #devProblems

Preface With .NET MAUI now available, I started to port my Xamarin.Forms applications to the new cool bits. The iOS version of my Fishing Knots app went quite smoothly, but I really had a lot of trouble with the Android version. First, I did not even get it to compile. After ironing out all the issues Rider was indicating, I finally got it compiling and was able to deploy it to the Android…

#CASBAN6 – How to create a facade to manage Azure Blob Storage with Azure Functions

I just blogged: #CASBAN6 – How to create a facade to manage Azure Blob Storage with Azure Functions #Azure #AzureFunctions #AzureDev #AzureBlob #Blob #Storage #API #dotNET #csharp #OpenAPI #Swagger #security

Why the facade? You might wonder why I am creating this facade to manage file uploads to the Azure Blob Storage. There are two main reasons. The first one is that I wanted to have a common endpoint for all interactions with Azure, also for file handling. The second one is security. The function app already has a high level of security by enforcing a Microsoft account, which is equally needed for…

#CASBAN6: How to configure Azurite to use DefaultAzureCredential with Docker on macOS

I just blogged: #CASBAN6: How to configure Azurite to use DefaultAzureCredential with Docker on macOS #Azurite #Azure #AzureStorage #Docker #macOS #AzureSDK

Before we will have a look at the promised facade for uploading files to Azure’s Blob storage, I want to show you how to configure Azurite to use the Microsoft Identity framework with Docker on macOS for local debugging. Using the Identity framework, our local debug environment and the productive rolled out functions will behave the same. If you have been following along, you should already have…

#CASBAN6: Add a Swagger (OpenAPI) page to Azure Functions

I just blogged: #CASBAN6: Add a Swagger (OpenAPI) page to Azure Functions #Swagger #SwaggerUI #OpenAPI #serverless #Azure #AzureFunctions #API #documentation #testing

Why? Adding a Swagger page to any API project (not only with Azure Functions) is nowadays one of the most common steps. Implementing the OpenAPI specification makes your API easily testable during development, and in the end, it provides an interactive documentation page to your API consumers. While these are the major advantages, you can go deeper into that topic on the OpenAPI website.…

How to lock orientation at runtime on iOS 16 with .NET MAUI and Xamarin.Forms

I just blogged: How to lock orientation at runtime on iOS 16 with .NET MAUI and Xamarin.Forms #iOS #iOS16 #iOSDev #dotNET #dotNETMAUI #XamarinForms #XamariniOS

The old way Before iOS 16, it was pretty easy to lock a Page into a certain orientation. It was basically just one line of code (if you don’t count the DependencyService boilerplate code in): UIDevice.CurrentDevice.SetValueForKey(new NSNumber((int)UIInterfaceOrientation.Portrait), new NSString("orientation")); By calling this method whenever the size of a page was allocated, we were able to…

Deploy MAUI apps with Rider on your iOS device after these Xcode errors

I just blogged: Deploy MAUI apps with Rider on your iOS device after these Xcode errors #Rider #dotNET #dotNETMAUI #MAUI #IDE #Xcode #iOS #VS4Mac #VisualStudio

The Error I am working a lot with .NET MAUI lately (both at work and for my private projects) and I use JetBrains Rider as the primary IDE on macOS. If you try to deploy an iOS app, your first attempt will likely fail with a big red error message like in the picture above. The details tell us that the error is coming from missing Xcode extensions: Failed to install application on device…

#CASBAN6: Implementing the API endpoints with Azure Functions

I just blogged: #CASBAN6: Implementing the #API endpoints with #AzureFunctions

After my last post, we have the base implementation ready to be used for our endpoints. As we already know, our endpoints will feature the CRUD pattern to interact with the endpoints. Please note: the code on GitHub is already a few steps ahead and may look a bit different from what I am posting here (mostly due to the OpenApi attributes, but you will be able to follow along). I will use the…

How to use the .NET CLI clean-up tools on macOS

I just blogged: How to use the .NET CLI clean-up tools on macOS #dotNET #macOS #tools #CLI #SDK #Runtime #workload #MAUI #dotNETMAUI #NuGet #MAUIDev #devtools #devlife

Earlier this week, the .NET SDK and Runtimes received some updates. Together with that, also Visual Studio for Mac was updated. Once I got past the installation of all updates, both Visual Studio and Rider were no longer restoring the required NuGet packages for my .NET MAUI project running on .NET 6. I eventually fixed that issue by cleaning up all the .NET SDKs, Runtimes, workloads and NuGet…

#CASBAN6: Function base class (and an update to the DTO models)

I just blogged: #CASBAN6: Function base class (and an update to the DTO models) #Azure #AzureFunctions #Serverless #DTO #dotNET #CSharp

After we have been setting up our Azure Function project last time, we are now able to create a base class for our Azure functions. The main goal is to achieve a common configuration for all functions to make our life easier later on. CRUD defintion Our API endpoints should provide us a CRUD (Create-Read-Update-Delete) interface. Our implementation will reflect this pattern as follows: A…
