I'm looking for the equivalent of C# default keyword, e.g:

public T GetNext()
{
    T temp = default(T);
            ...

Thanks

I found this in a blog: "What does this C# code look like in F#? (part one: expressions and statements)"

C# has an operator called "default" that returns the zero-initialization value of a given type:

default(int)

It has limited utility; most commonly you may use default(T) in a generic. F# has a similar construct as a library function:

Unchecked.defaultof<int>
