Instantiate array in F#?

In C# I'd write something like

MyType arr = new MyType[10];

to alloc arr as array which has 10 items of type MyType.

How to do the same in F# ??

let mutable arr = ?????????????

To initialise the array to the default (e.g. null or zero), use Array.zeroCreate:

let arr : int array = Array.zeroCreate 10

To initialise with a value, use Array.init.
