latitude and longitude bounding box for C#?

Question

I just want to find a straightforward, C# class that takes in a starting latitude and longitude and a distance and finds the bounding box (max lat, min lat, max lon, min lon

Answer 1

If you only have a starting latitude, longitude and altitude then there is no bounding box as you have only defined a single point in space. Any rectangle/bounding box would require at least two points to define it!
