Re: [PDFNet] Could not load file or assembly 'PDFNet.dll' ' when using PDFNet for .NET 4.x

[Ryan Barr]

The PDFNet x64 library is for targeting frameworks 2.0 - 3.5. Since your building .net 4 or 4.5, you should use PDFNet for .Net 4.

You can see the libraries and the frameworks they target at this link

If there is some reason to use the .Net 2 assembly, the following article might help.

Hi, I'm trying to develop a sample, blank web application including the PDFNet x64 dll. So I create the app from the standard VS2012 web form template and run it. Then I try to add the PDFNet dll.
If I run the test web app on .NET 3.5 no problem. If I run it in .NET 4 or 4.5 I get this error:

I have already searched a lot on the web and in this group, and I have already tried the solutions proposed for instance in

https://groups.google.com/forum/?fromgroups=#!newtopic/pdfnet-sdk/pdfnet-sdk/jXBDWdV0_NQ

or

https://groups.google.com/forum/?fromgroups=#!newtopic/pdfnet-sdk/pdfnet-sdk/OqVycSlOlB0

or others similar, but to no avail. I'm running a Windows 8 machine x64 with all versions of .NET up to 4.5 installed, and I DO have the Microsoft Visual C++ 2010 x64 Redistributable installed on my PC. I have also tried copying both the msvcr100.dll and msvcp100.dll to the output bin folder, but I still get this error. I then thought that maybe it was the fault of VS2012 development server which runs in x86 mode, so I have set up a website on IIS and run it from there on x64, but still the same result. I am a bit bereft, does anybody have any idea? Thanx.
