Hello,

we looked in to the issue and can confirm that this is a False Positive. The minimal code that raises the issue is

public void UsedInFinally_AfterOtherAssignment()
{
    int value = 42;
    try
    {
        SomethingThatCanThrow();
    }
    catch (Exception ex)
    {
        value = 0; // Noncompliant False Positive
        throw;
    }
    finally
    {
        object o;
        o = ""; // Any assignment (also var s = ""; or var o = new object();) hides the usage of value in the next line
        Use(value);
    }
}

We added this False Positive to our backlog.

Best, Martin
