SimTuning

A .NET MAUI app for two-stroke engine simulation & dyno tuning (exhaust/resonance, intake, engine, and dyno/audio modules). Targets .NET 11 (net11.0-ios, net11.0-maccatalyst, net11.0-windows, net11.0-android).

The codebase was recently migrated from .NET 10 to .NET 11 (TFMs, NuGet, modern C#, DI, async, security hardening, dead-code removal, and a real test suite). See PR #108 for the full modernization summary.

Developing

This project targets the .NET 11 SDK (currently the 11.0.100-preview.6 preview). global.json pins the exact version (allowPrerelease: true), so install that SDK and the workloads below.

• SDK: https://dotnet.microsoft.com/en-us/download/dotnet/11.0
• global.json → "version": "11.0.100-preview.6.26359.118"

Setup

sudo dotnet workload restore     # installs maui-ios, maui-maccatalyst
cd src/
dotnet build

On macOS, also make sure Xcode is selected (sudo xcode-select -s /Applications/Xcode.app/Contents/Developer) and its license accepted (sudo xcodebuild -license accept).

Running the App

Using Visual Studio Code (Recommended)

1. Install the .NET MAUI extension in VS Code
2. Press F5 or use the Run menu
3. Select target: macOS, iOS Simulator, or iOS Device

Command Line

macOS (Mac Catalyst)

cd src/SimTuning.Maui.App
# Build the app
dotnet build -f net11.0-maccatalyst -p:RuntimeIdentifier=maccatalyst-arm64

# Open the app
open bin/Debug/net11.0-maccatalyst/maccatalyst-arm64/SimTuning.app

iOS Simulator (requires compatible Xcode/SDK)

cd src/SimTuning.Maui.App
# List available simulators and boot one
xcrun simctl list devices available | grep iPhone
xcrun simctl boot <SIMULATOR_UDID>

# Build for iOS simulator
dotnet build -f net11.0-ios -p:RuntimeIdentifier=iossimulator-arm64

Note: the net11.0-ios app build needs an iOS simulator runtime that matches the installed Xcode. If the iOS build fails with a simulator-runtime mismatch, run xcodebuild -downloadPlatform iOS. The MacCatalyst target builds green without it.

Tests

The SimTuning.Test project is a plain net11.0 xUnit suite (51 tests) — no MAUI host required, so it runs in the headless test runner:

dotnet test src/SimTuning.Test

Formatting

C# is formatted with csharpier (config in .csharpierrc.json, useTabs: false); XAML and other files use prettier (config in .prettierrc.json).

# C# — csharpier (global tool: `dotnet tool install -g csharpier`)
dotnet csharpier .

# XAML / JSON / Markdown — prettier
npx prettier --write "**/*.xaml"

⚠️ Do not run csharpier recursively on the whole tree if a prettier is also in scope — a phantom prettier can reformat ~70 unrelated C# files. Format the C# and XAML sets separately as shown above.
