Question 1

How to calculate sunrise time in C# using CoordinateSharp?

Accepted Answer

Initialize a Coordinate with location and date, then access the CelestialInfo.SunSet property. For example, after creating a Coordinate, use c.CelestialInfo.SunSet to get the sunrise time based on the input.

Question 2

CoordinateSharp vs GeoCoordinate for .NET – which is better?

Accepted Answer

CoordinateSharp offers more features like celestial calculations and extensive format conversions, while GeoCoordinate is simpler but limited to basic coordinate handling. Choose CoordinateSharp for advanced geospatial tasks, but be aware of its performance trade-offs.

Question 3

Is CoordinateSharp free for commercial use?

Accepted Answer

No, free use is only under AGPL-3.0, which requires open-sourcing your software. For proprietary projects, you must purchase a commercial license from the website, as stated in the licensing section.

Question 4

How to improve performance in CoordinateSharp?

Accepted Answer

Turn off eager loading for unused features, such as celestial calculations, by adjusting settings. The 'Performance Tips' page recommends this to reduce initialization time by 6-10ms for specific use cases.

Question 5

Does CoordinateSharp support real-time GPS data?

Accepted Answer

It calculates data based on input coordinates and dates, not real-time feeds. For live GPS updates, you need to manually update the Coordinate object with new locations, as it doesn't integrate directly with streaming APIs.

Question 6

Can I use CoordinateSharp with .NET Core?

Accepted Answer

Yes, it's compatible with .NET Standard 1.3+, so it works with .NET Core, .NET 5.0+, and other modern runtimes, as listed in the prerequisites. This makes it versatile for cross-platform .NET development.
