XlsIO: 'Unable to find an entry point named 'CopyMemory' in DLL 'kernel32.dll' on workbook.SaveAs(filename)

Question

I'm building an application that creates an Excel file. I'm using WPF, .NET Core, and Syncfusion File Formats. Once I have created the worksheet I attempt to save it with the SaveAs function. I receive the exception: System.EntryPointNotFoundException: 'Unable to find an entry point named 'CopyMemory' in DLL 'kernel32.dll'.'

Has anyone else seen this? Any recommended solution?

Thank you.
