Build from source

Install the .NET 10 SDK, .NET MAUI workloads, and the platform tools for your target. Open OneGateApp.slnx, select OneGateApp as the startup project, and choose a device or emulator. iOS and macOS development require a Mac with a compatible Xcode installation.

For example, to build Android from the repository root:

dotnet build OneGateApp/OneGateApp.csproj -f net10.0-android

See the development guide for platform setup, signing, dependencies, notification configuration, and validation. Windows supports local notifications; remote WNS setup is not included in this checkout.
