FileNotFoundException. Dot net Standard

I am attempting to convert a docx file to a pdf file using Aspose.Words 18.2 with dot net standard. Here is my code to convert to pdf

public static void Convert(Stream input, Stream output)
   var doc = new Aspose.Words.Document(input);
   doc.Save(output, Aspose.Words.SaveFormat.Pdf);

Its failing on the var doc line with a FileNotFoundException. Its a stream not a directory.

Hello @awais.hafeez

I have attached the project I was using to test the functionality of Aspose.Words and Aspose.PDF using the dot net core dlls. In the attachment, I have also place the docx file I was using as an example. The Aspose.PDF also gives and error as well.


I am afraid, I do not see any projects in this thread. You may also upload to Dropbox and share the Download link here.

@awais.hafeez, Sorry about that.

here is the project link:


We created a fresh .NET Core 2.0 Console Application (see (235.4 KB)) , installed Aspose.Words for .NET 18.3 via NuGet and were unable to observe this issue on our end.
