FileNotFoundException after upgrading

Aspose.Total Product Family

I am attempting to upgrade the version of Aspose I am using in my project and running into an issue.

System.IO.FileNotFoundException was unhandled
  Message=Could not load file or assembly 'aspose.foundation-1.7.9-net20, Version=1.7.9.0, Culture=neutral, PublicKeyToken=716fcc553a201e56' or one of its dependencies. The system cannot find the file specified.

  InnerException:

I was using

Aspose.Cells 7.3.3.0
Aspose.Pdf 7.4.0.0
Aspose.Slides 6.7.0.0
Aspose.Words 11.8.0.0

and I updated to
Aspose.Cells 7.4.2.0
Aspose.Pdf 7.8.0.0
Aspose.Slides 7.2.0.0
Aspose.Words 13.2.0.0

I was able to use these assemblies with the exact same license file and code in a small console app I wrote but when I updated the assemblies in my main project I get the previous error. My project is using .Net 3.5 x64.

Hi John,


Thanks for your inquiry. Can you please double check whether you are referencing latest dll of Aspose.Pdf in your project? Hopefully it will fix the issue. If issue persist then please share your sample project and source document here? So we will test it at our end and will provide your more information accordingly.

Sorry for the inconvenience faced.

I can verify that I am using the latest assemblies which I indicated in the post above.

public class PdfConverter : IConverter
{
    private Document Document { get; set; }
    public int TotalPages { get; protected set; }
    public int CurrentPageNumber { get; protected set; }
    public Stream CurrentPage { get; protected set; }

    public PdfConverter(Stream document)
    {
        document.Seek(0, SeekOrigin.Begin);
        Document = new Document(document);
        TotalPages = PublishHelper.GetPageCountPdf(document);
        CurrentPageNumber = 0;
    }

    public bool NextPage()
    {
        if (++CurrentPageNumber > TotalPages)
            return false;

        CurrentPage = new MemoryStream();
        Document newDoc = new Document();
        newDoc.Pages.Add(Document.Pages[CurrentPageNumber]);
        newDoc.Save(CurrentPage);
        newDoc.Dispose();
        CurrentPage.Seek(0, SeekOrigin.Begin);
        return true;
    }
}

The red line is where I am getting the error. This code runs fine when loaded in a small console app, however, when I run it in my main project, I get the error. The assemblies are the same between the two projects. The stream being passed into the constructor is a pdf file.

Hi John,


Thanks for your patience. I’ve tested the scenario with Aspose.Pdf for .Net 7.8.0, using your sample code and I’m afraid I’m unable to notice the reported issue. Could you please share a sample project to replicate the issue and please also confirm how you are referencing the Aspose.Pdf dll in your project from GAC or else?

Sorry for the inconvenience faced.

Unfortunately I am unable to reproduce the issue in a sample program. The Aspose.Pdf dll is being deployed to the GAC.

I am also using this from within SharePoint 2010. I have not yet tried the latest version of Aspose.Pdf but I will as soon as I get a chance.
