[NoureddineEl-zaatari]

Hello,

i have a map in Geographic coordinate, what i want to do is that snap a point at 90 degrees angle to a line, i have the start and the end points of the line and i have the location of the point itself,

im looking for a generic solution, i dun want to use the snapping helpers, i want it through equations,,

thanks for any help,

this is solved, ESRI.ArcGIS.Mobile.Sketch snapping classes are exposed now, you can use them directly,, i tired it and it works
