Hi

I'm very new to F# and I'm trying to make a struct for storing polygons:

1
2
3
4
5

type Polygon =
    struct
        val Coords : list
        new(list_of_Coords) = { Coords = list_of_Coords }
    end

but Visual studio says "The type 'Microsoft.FSharp.Collections.list<_>' expects 1 type argument(s) but is given 0"

I think not as I don't intend to initialise the list in the struct - just declare it.

This is my Coords code:

1
2
3
4
5
6

type Coord =  //Datatype til kort
    struct
        val X : float;
        val Y : float;
        new(x,y) = { X = x; Y = y }
    end

By the way, how come nothing happens when I rightclick the error text and select "Show error help" - shouldn't I get pointed to a help page?

kind regards Jon Loldrup
