out var treated as non-nullable

[cston]

out var is treated as non-nullable, regardless of parameter declaration.

class C
{
    static void TryGet(out string? s)
    {
        s = null;
    }
    static void Main()
    {
        TryGet(out var s); // string with null assignment warning
        int n = s.Length;  // no warning
    }
}

I'll take this one as part of the TryGetValue scenario with [NotNullWhenTrue] attribute.

Confirmed this was fixed. Closing
