Description Dominik Weber 2016-04-06 01:11:52 UTC
When setting the device language to czech the following code does NOT work:

            var n1 = "SEARCHFIELDS";
            var n2 = "Searchfields";

            var same = string.Equals(n1, n2, StringComparison.OrdinalIgnoreCase);

            var dict = new Dictionary<string, string>(StringComparer.OrdinalIgnoreCase);
            dict[n1] = "test";
            var x = dict[n2];

Expected result: same==true, x=="test"
Actual result: same==true, x==KeyNotFound exception

when switching the device language to US the code works perfectly.

This fails on XI 9.6.x (c6) which is based on mono 4.2.x.

But it works on XI 9.8 (c7) and maccore/master - both using mono 4.4.x.

So it looks like it was a mono issue that has already been fixed. I'll add your code snippet into our test suite to ensure it cannot regress again. Thanks!
