Find uncaught exceptions in C# code

问题

I'm wondering if there is a tool to find uncaught exceptions in C# using static code analysis? Basically I want to select a methodA() and want a list of all exceptions thrown by methodA() and all methods called by methodA(). I tried ReSharper + Agent Johnson and AtomineerUtils, both fail this simple task.

Here's my example code:

public class Rectangle
{
    public int Width { get; set; }
    public int Height { get; set; }

    public int Area()
    {
        CheckProperties();
        long x = Width * Height;
        if (x > 10)
            throw new ArgumentOutOfRangeException();
        return (int) x;
    }

    private void CheckProperties()
    {
        if (Width < 0 || Height < 0)
            throw new InvalidOperationException();
    }
}

The tool should be able to tell me (in any form) that method Area() will throw ArgumentOutOfRangeException or InvalidOperationException.

I used an R# addin once that did that in the IDE - Exceptional. Bad idea, turns out that it complains about every single string.Format call and similar common cases that may indeed throw, but that won't cause issues.
