Currency Symbols sample

A separate MAUI app consuming only the Plugin.Maui.Currency reference plugin through the local NuGet feed. This example verifies reusable plugin packaging; it is optional for applications using NativeChannels, and the plugin has not been published to NuGet.org. It has no project references, native source references, explicit AAR imports, or explicit XCFramework imports.

Enter a currency code or tap USD, EUR, GBP, or JPY. The displayed symbol comes from Android java.util.Currency, Apple NSLocale, or Windows CurrencyFormatter, using the device locale. Try ZZZ to see an unknown-code error.

Follow the plugin build instructions to produce the local NuGet and restore this sample into a fresh cache. eng/restore-currency-sample.sh cleans generated outputs and verifies that all NativeChannels/plugin archives match the local feed.

On first appearance, the app runs real native checks for concurrent lookups, normalization, unknown codes, malformed codes, cancellation, and a successful call after cancellation. It displays the result, writes currency-result.txt to its app data directory, and logs CURRENCY_SAMPLE PASS android: … or CURRENCY_SAMPLE PASS apple: … / CURRENCY_SAMPLE PASS windows: …. The verification scripts fail if the result is absent or reports failure.

Windows (0.5 framework preview)

./eng/verify-windows.ps1 -Currency

Run from the repository root with the pinned SDK and maui-windows workload. This builds the Windows Plugin.Maui.Currency 1.1.0-alpha.1 development package, runs its Windows tests, restores this app from the local feed, and executes the Release x64 app. The app still has only one direct package reference. Use -BuildOnly for adapter tests and compilation without UI execution. See the Windows plugin guide.

Android and Apple

# Android arm64 emulator
bash eng/restore-currency-sample.sh -p:TargetFrameworks=net10.0-android -r android-arm64
bash eng/dotnet.sh build samples/Maui/Currency -c Release -f net10.0-android -r android-arm64 --no-restore
bash eng/verify-android-currency.sh EMULATOR_SERIAL Release android-arm64

# iOS arm64 simulator
bash eng/restore-currency-sample.sh -p:TargetFrameworks=net10.0-ios -r iossimulator-arm64
bash eng/dotnet.sh build samples/Maui/Currency -c Release -f net10.0-ios -r iossimulator-arm64 --no-restore
bash eng/verify-ios-currency.sh SIMULATOR_UDID Release

Use android-x64 for an x86_64 emulator. See the verification record for executed versus compile-only targets. Packages remain local; these commands do not publish them.

The framework-independent verification helper is linked from samples/Currency.Shared/PluginVerification.cs, so other hosts can use the same scenarios without depending on MAUI.
