  hello
  
  I’m migration an application from .Net4.7 framework to .Net8, which I understand is supported.

  The following error arised :

  Error (active)	CS0029	Cannot implicitly convert 
  type 'System.Drawing.Font' 
  to 'GrapeCity.ActiveReports.Document.Drawing.Font'	
  

  looks like the implicit convertors defined in
  
  MESCIUS.ActiveReports.Core.Document.4.4.0\lib\net462\MESCIUS.ActiveReports.Core.Document.dll
  
  are not available in mescius.activereports\18.1.0\lib\netcoreapp3.1\MESCIUS.ActiveReports.dll

  am I missing something for this code to target .Net8 successfully ?

  Hi Gerardo,

  This observation is because ActiveReports 17 and onwards has dropped it’s dependency on System.Drawing DLL from the code as a part of its Breaking Changes for cross-platform compatibility in Section Reports.

  You can fix this issue by using ‘GrapeCity.ActiveReports.Document.Drawing.Font’ instead of ‘System.Drawing.Font’. Please refer to the following code for reference:

  textbox1.Font = new GrapeCity.ActiveReports.Document.Drawing.Font("Arial", 14, GrapeCity.ActiveReports.Document.Drawing.FontStyle.Bold);
  
  

  You may also check the Breaking Changes in ActiveReports 17 here: Breaking Changes from ActiveReports 16 to ActiveReports 17

  We hope this helps!

  thanks Katyayny,

  I see objects like GrapeCity.ActiveReports.SectionReportModel.Label
  
  have property Location of type System.Drawing.PointF

  how this case is handled platform in dependently?

  Hi Gerardo,

  As per Microsoft, System.Drawing.PointF is under System.Drawing.Primitives which is still supported in cross-platform mode. As per Microsoft, System.Drawing.Common is only supported on Windows. Classes like System.Drawing.Font and System.Drawing.Image have been removed from System.Drawing.Common by Microsoft, due to which we had to introduce classes like GrapeCity.ActiveReports.Document.Drawing.Font and GrapeCity.ActiveReports.Document.Drawing.Image to support cross-platform compatibility. Please note that we have removed dependency on System.Drawing from our code for functionalities such as image handling, text measuring, printing, etc.

  You may also refer to the attached documentations link referring to the same:

  • https://learn.microsoft.com/en-us/dotnet/core/compatibility/core-libraries/6.0/system-drawing-common-windows-only
  • https://learn.microsoft.com/en-us/dotnet/api/system.drawing?view=net-8.0#:~:text=However%2C%20primitive%20types%20in%20the%20namespace%2C%20such%20as%20System.Drawing.Color%2C%20System.Drawing.Size%2C%20System.Drawing.Point%2C%20and%20System.Drawing.Rectangle%2C%20can%20be%20used%20in%20any%20application.

  We hope this helps!
