Hello Support,
my solution has been updated with Spire.Officefor.NETStandard Version 9.3.1 but i received this exception during spire.Document class instantiation.

---> System.IO.FileNotFoundException: Could not load file or assembly 'System.Security.Permissions, Version=4.0.1.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. The system cannot find the file specified.

File name: 'System.Security.Permissions, Version=4.0.1.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'

Hello William,
i found a workaround, indeed adding <PackageReference Include="System.Security.Permissions" Version="8.0.0" /> it works properly.
