SimConnect.NET
A modern, high-performance C# wrapper for Microsoft Flight Simulator's SimConnect SDK. It simplifies flight simulation development by providing async/await patterns and high-level abstractions, enabling real-time aircraft data monitoring, AI object management, and seamless integration with the simulator through a clean, type-safe API.
⚠️ Beta Software Notice
SimConnect.NET is currently in beta development. APIs may change, features may be added or removed, and breaking changes are expected between releases. Use in production environments at your own discretion and always test thoroughly before deploying.
Features
- Async/Await Support: Modern asynchronous patterns for all SimConnect operations
- High-Level Abstractions: Simplified API for common flight simulation tasks
- Type-Safe Interface: Strong typing with automatic data type inference
- Real-Time Data: Efficient aircraft data monitoring and SimVar access
- AI Object Management: Create and manage AI aircraft and objects
- Multi-Framework Support: Compatible with .NET 8.0 and .NET 9.0
Quick Start
Install the NuGet package:
dotnet add package SimConnect.NETBasic usage example:
using SimConnect.NET; var client = new SimConnectClient(); await client.ConnectAsync(); // Get aircraft data var altitude = await client.SimVars.GetAsync<double>("PLANE ALTITUDE", "feet"); var airspeed = await client.SimVars.GetAsync<double>("AIRSPEED INDICATED", "knots"); Console.WriteLine($"Altitude: {altitude:F0} ft"); Console.WriteLine($"Airspeed: {airspeed:F0} kts");
Requirements
- Microsoft Flight Simulator 2020 or later
- .NET 8.0 or .NET 9.0 runtime
- SimConnect SDK (included with Flight Simulator)

### Added
- Set multiple SimVars in one shot by passing a struct to `SimVars.SetAsync<T>()`, mirroring the existing struct-based reader pipeline.
- Internal field-writer pipeline that packs annotated struct fields into the unmanaged buffer used for SimConnect writes.
- Test coverage that exercises struct-based sets, validates altitude adjustments, and restores the original values afterward.
### Performance
- Wrapped verbose debug logging in hot paths with `SimConnectLogger.IsLevelEnabled` checks to avoid string allocations and GC churn when debug logging is disabled.
### Fixed
- Updated the AI object lifecycle test to spawn the `CoffeeCup` model so it no longer times out on missing assets.
- Stabilized the performance timeout test by ensuring the cancellation token fires before issuing the request.
### Notes
- Thanks to @bstudtma for the contribution in PR #11.
