The MAUI & Xamarin tracker

A complete guide to passing data through Shell navigation in .NET MAUI 11: registering global routes, string query parameters, QueryPropertyAttribute vs IQueryAttributable, the URL-decoding asymmetry between the two, single-use ShellNavigationQueryParameters vs the IDictionary overload that leaks, passing data backwards with ..?key=value, and why QueryPropertyAttribute is not trim safe.

Port your ads layer from Xamarin.Forms to .NET MAUI: what to delete (MTAdmob, custom AdView renderers, Xamarin.GooglePlayServices.Ads bindings), what replaces it in Plugin.AdMob, and a line-by-line API mapping for banner, interstitial, rewarded, rewarded interstitial and app open — plus the singleton-to-DI shift and the UMP consent gap that stops ads serving in the EEA.

A practical, end-to-end guide to monetizing a .NET MAUI app with Google AdMob using Plugin.AdMob. Install one NuGet, call UseAdMob(), and wire up banner, interstitial, and rewarded ads — with consent built in via UMP, test ad units, the exact service APIs, preloading patterns, and a production checklist. Tested on .NET 10 / MAUI.

Plugin.AdMob now renders native video ads. Drop a MediaView into your NativeAdView template, request video with VideoOptions, and wire up the OnVideoStart/Play/Pause/End lifecycle events — including the custom-controls caveat that trips everyone up on AdMob inventory. Full walkthrough with a complete working example, tested on Android with the native video demo unit.

.NET 11 Preview 6 removes the separate Mono path for MAUI on Android, iOS, and Mac Catalyst. CoreCLR is now the only mobile runtime, the UseMonoRuntime escape hatch is closed, and GA is set for November 2026.

SkiaSharp 4.148.0 is the first stable v4 release. GPU-heavy UIs render up to 24% faster, CPU shaders run ~6x faster, and the legacy API surface is finally retired. Here is what upgrading actually costs you.

End-to-end migration from Xamarin.Forms 5.0 to .NET MAUI 11 GA on net11.0, covering csproj rewrite, custom renderer to handler conversion, AppShell wiring, DependencyService removal, MessagingCenter retirement, Resizetizer assets, and the gotchas that bite a real production codebase.

For a greenfield mobile app in 2026, pick Flutter 3.44 when pixel-identical UI and animation budget matter, React Native 0.82 when your team already lives in TypeScript and you need a real browser sibling, and .NET MAUI 11 when iOS and Android are part of a wider .NET product and you need first-party Microsoft support.

MAUI 10 SR6 (10.0.60) extends Material 3 theming to Button, Entry, SearchBar, DatePicker, Slider, ProgressBar, ImageButton, Switch, and Shell on Android. Opt in with one MSBuild property. No custom renderers, no styles.xml edits.

For a new .NET cross-platform desktop and mobile app in 2026, pick Avalonia when you need a single rendered control set across all targets, Uno when you must reach the browser too, and MAUI only when you actually need native iOS and Android plus first-party Microsoft support.

The profile Visual Studio picked was generated before this iPhone's UDID was registered. Re-register the device, regenerate the development profile, redownload, redeploy.

Xcode 15+ ships without bundled iOS simulator runtimes. MAUI fails the build when SupportedOSPlatformVersion has no matching runtime installed. Install one with xcodebuild -downloadPlatform iOS or via Xcode Settings, then verify with xcrun simctl list runtimes.

Nine out of ten times the real Gradle error is buried higher in the MSBuild log. JDK 17 path, missing maui-android workload, and Windows long paths are the usual root causes.

.NET 11 Preview 4 makes CoreCLR the default runtime for MAUI on Android, iOS, Mac Catalyst, and tvOS. Mono is still one MSBuild property away. Here is what changes, what breaks, and how to opt out.

.NET 11 Preview 4 turns on dotnet watch for Android devices, Android emulators, and the iOS Simulator. Edit, save, and the running app updates without a manual rebuild. One csproj gotcha applies to iOS.

Step-by-step migration from Xamarin.Forms 5.0 ListView to .NET MAUI 11 CollectionView for apps that already squeezed performance out of ListView. Covers cell recycling, virtualization, grouping, pull-to-refresh, context actions, selection, ItemsLayout, EmptyView, and the gotchas that bite real apps.

End-to-end guide to packaging a .NET MAUI 11 Windows app as an MSIX, bundling x64/x86/ARM64 into a .msixupload, and submitting through Partner Center: identity reservation, Package.appxmanifest, dotnet publish flags, MakeAppx bundling, and the Store-trusted certificate handoff.

End-to-end drag-and-drop in .NET MAUI 11: DragGestureRecognizer, DropGestureRecognizer, custom DataPackage payloads, AcceptedOperation, gesture position, and the per-platform PlatformArgs traps on Android, iOS, Mac Catalyst, and Windows.

End-to-end dark mode in .NET MAUI 11: AppThemeBinding, SetAppThemeColor, RequestedTheme, UserAppTheme override with persistence, the RequestedThemeChanged event, and the per-platform Info.plist and MainActivity bits that the docs gloss over.

Strip Android and iOS from a .NET MAUI 11 project so it ships Windows and Mac Catalyst only: the csproj edits, the workload commands, and the multi-targeting that keeps your code clean.

SkiaSharp 4.0 Preview 1 lands with Uno Platform as co-maintainer alongside the .NET team. SKPath becomes immutable behind a new SKPathBuilder, and HarfBuzzSharp gets full OpenType variable font axis control.

.NET MAUI 11 Preview 3 adds built-in pin clustering to the Map control on Android and iOS, with ClusteringIdentifier groups and a ClusterClicked event.

.NET MAUI 11 Preview 3 adds LongPressGestureRecognizer as a first-party gesture, with duration, movement threshold, state events, and command binding, replacing the common Community Toolkit behavior.
