This is my code, trying to generate a crystal report in a class library project and return it as a stream, because I’m going to use this library in a .Net Core web API project.

public byte[] GenerateReport(string reportPath) 
{
    try
    {
        ReportDocument reportDocument = new ReportDocument(); //Error occures here
        reportDocument.Load(reportPath);

        using (MemoryStream stream = new MemoryStream())
        {
            reportDocument.ExportToStream(ExportFormatType.PortableDocFormat).CopyTo(stream);
            return stream.ToArray(); 
        }
    }
    catch (Exception ex)
    {
        // Handle exceptions here
        throw new Exception($"Error generating report: {ex.Message}");
    }
}

I’m getting the following error. Anyone to help with this issue?
I’m using visual studio 2022, Class library is targeting .net framework 4.7.2
