Hello,

ReSharper is right, first argument should be parameter name, and the second
(if any) can be message. So you should rewrite it as

throw new ArgumentOutOfRangeException("value", "value must be greater than
0");

It is known mess in .NET API, because ArgumentException, which is base class
for ArgumentOutOfRangeException has the reverse order of parameters. That's
why we introduced this check :)

Ohh I see. Good catch.

I was using the overload public ArgumentOutOfRangeException(string paramName), but expecting it just to be "message", as most .NET exceptions.
