I have several issues with version 2023.12.14 (using a WinForms project targeting .NET Framework 4.8 ):

* A reference to System.Text.Json is required at runtime. I can compile without this reference, though. Shouldn't this dependency be taken care of by the NuGet package?

* The TeeChart Editor causes an exception regarding a missing assembly PdfSharpCore when clicking on certain tabs in the editor (e.g. the "Legend" tab). I tried adding both the latest stable v1.3.62 as well as the version 1.3.57 of PdfSharpCore specified in the exception message via NuGet to the project, but to no avail. The exception keeps occurring. Shouldn't this dependency be taken care of by the TeeChart NuGet package too?

Code: Select all

System.IO.FileLoadException: 'Die Datei oder Assembly "PdfSharpCore, Version=1.3.57.0, Culture=neutral, PublicKeyToken=null" oder eine Abhängigkeit davon wurde nicht gefunden. Eine Assembly mit starkem Namen ist erforderlich. 

* In the "Series" tab of the Editor (which is one of the tabs that can be displayed without causing an exception), line series are displayed as filled rectangles (see screenshot), instead of with a line symbol as was the case in previous TeeChart versions

* Trying to test the fix for bug 2635 (legend checkboxes replacement), I still get similar issues as with TeeChart 2023.11.17, which I posted about here:
** Setting Legend.CheckBoxes = True in the code is still possible, but has no effect (why not remove the property completely?)
** Setting Legend.FontSeriesColor = True causes a System.NullReferenceException on load
** Sometimes, clicking a legend item will deactivate a different series than the one clicked. This seems to happen in particular when you have more than just a couple of series in the chart (this was also reported by someone else for version 4.2023.11.6

I have attached a very simple test project for reproducing these issues.

I also found out that in order to use the new feature where deactivated legend items are shown as strike-through or faded, I have to set TChart1.Legend.ActiveStyle to something other than None. Where do you communicate this kind of information about new features to your users? Am I missing some source of information about new releases? Because it is not mentioned in https://www.steema.com/version_info/net/last nor ist it documented in https://www.steema.com/docs/TeeChartNETReference.htm
