  Hi ,

  When I change the Spread.NET version from 18 to 19, the following warnings are produced during the build. Could you tell me the possible causes and solutions?

  warning :
  
  NU1202:Package ‘sa3client’ 1.2.0 is not compatible with netcoreapp2.1 (.NETCoreApp,Version=v2.1) / any.

  My Project :
  
  Target Framework - .Net Framework 4.6.2
  
  Spread.NET installed via NuGet - GrapeCitySpreadWinForms / Mescius.Spreadseet.Core

  Best regards

  Hello,
  
  We created a simple sample project targeting .NET Framework 4.6.2 using GrapeCity.Spread.WinForms v18 (with Mescius.Spreadsheet.Core installed as a transitive dependency), and then upgraded the project to v19. However, we were unable to reproduce the behavior you reported.
  
  Sample: Spread_Sample.zip
  
  Could you please let us know if we might be missing any steps? Alternatively, you may update the attached sample or share a minimal, stripped-down version of your project so that we can investigate the issue further.
  
  Regarding the reported warning (NU1202): this is a NuGet compatibility warning, not a Spread.NET–specific runtime error. It indicates that one of the packages in your dependency graph targets .NET Core only, while your project targets .NET Framework 4.6.2.
  
  From the details provided, the warning appears to be caused by the sa3client package. This package is not installed by GrapeCity.Spread.WinForms, either in v18 or v19, so we are unsure which direct dependency is introducing it into your project.
  
  Could you please share a list of all ComponentOne (C1) / MESCIUS NuGet packages currently installed in your project?
  
  Regards,
  
  Uttkarsh.
