Hi, please help, we are using Aspose.PDF for HTML to PDF conversions and encountering a blocking error when upgrading to .NET 8 or .NET 9, I have tried various versions of Aspose.PDF and the latest stable version 25.2.0. Here is the code that I’ve isolated into a c# unit test:
[Fact]
public void Convert_html_to_pdf_2()
{
// Arrange
var html = @"<html xmlns=""http://www.w3.org/1999/xhtml"">
| Stock |
// Act
var input = new MemoryStream(Encoding.UTF8.GetBytes(html));
var document = new Document(input, new HtmlLoadOptions());
var memoryStream = new MemoryStream();
document.Save(memoryStream);
var actualPdfBytes = memoryStream.GetBuffer();
Array.Resize(ref actualPdfBytes, (int)memoryStream.Length);
// Assert
}
The error is as follows:
Message:
System.InvalidOperationException : Enumeration already finished.

AsposePdfGeneratorTests.Convert_html_to_pdf_2() line 65
RuntimeMethodHandle.InvokeMethod(Object target, Void** arguments, Signature sig, Boolean isConstructor)
MethodBaseInvoker.InvokeWithNoArgs(Object obj, BindingFlags invokeAttr)
Is this a known issues and/or is there any workaround that can be suggested because this is unfortuntely blocking us from upgrading our version of .NET
Thanks
ALSO NOTE: The following unit test passes and so it seems related to the handling of preserving whitespace:
[Fact]
public void Convert_html_to_pdf_1()
{
// Arrange
var html = @"<html xmlns=""http://www.w3.org/1999/xhtml"">
| Stock |
// Act
var input = new MemoryStream(Encoding.UTF8.GetBytes(html));
var document = new Document(input, new HtmlLoadOptions());
var memoryStream = new MemoryStream();
document.Save(memoryStream);
var actualPdfBytes = memoryStream.GetBuffer();
Array.Resize(ref actualPdfBytes, (int)memoryStream.Length);
// Assert
}
