I have this code which works perfectly everywhere else:

                #pragma warning disable
                if (Configuration.Window.RememberPosition)
                    if (ID == null)
                    if (!WindowInfo.ContainsKey(ID))
                        Core.DebugLog("Invalid key for window: " + ID);
                    Info info = WindowInfo[ID];
                    info.X = this.Left;
                    info.Y = this.Top;
                    info.Width = this.Width;
                    info.Height = this.Height;
                #pragma warning enable

but after I upgraded mono on my system (this happens now both on debian as well as ubuntu) I am getting errors from xbuild like this:

removal of #pragma lines apparently fix the problem, but it should work, it does in visual studio and older xbuild / mono for sure
Comment 2 Marek Safar 2014-07-15 08:06:20 UTC
This is kind of expected.

"#pragma warning enable" is wrong syntax. You need to use #pragma warning restore.

Recent versions give better error message
