Question

I am using a using Microsoft.FSharp.Core.Collections.FSharpMap
and very often have to write:

var oo = world.Entity.TryFind(t);
var entity = oo == null ? null : oo.Value;

And similar. Any suggestions for a better style?

Answer 1

You could write an Extension Method:

public static T ValueOrDefault<T>(this FSharpOption<T> option)
{
    return option == null ? default(T) : option.Value;
}

Usage:

var entity = world.Entity.TryFind(t).ValueOrDefault();
