Hi,

I have a need to work with PDFIUM.NET in a ASP.NET Core App (targetting .NET Framework)
I've used the typical PdfCommon.Initialize command to register the licence but then I get a

Patagames.Pdf.Net.Exceptions.NoLicenseException: 'The requested operation cannot be completed due to a license restrictions. The requested operation cannot be completed due to a license restrictions. You need to have a full license to be able to complete this operation.' on first API call.

The exact same code works in a Console app

Any clue on how to activate in this environment ?

Thanks

The code is :
Code:

            //Gets the location of the current assembly as URI
            string codeBase = System.Reflection.Assembly.GetExecutingAssembly().CodeBase;
            UriBuilder uri = new UriBuilder(codeBase);
            string assemblyPath = Uri.UnescapeDataString(uri.Path);
            //Gets directory for assembly

            var DllFolder = Environment.Is64BitProcess ? "x64" : "x86";
            var PdfiumPath = System.IO.Path.Combine(System.IO.Path.GetDirectoryName(assemblyPath), $@"{DllFolder}\pdfium.dll");
            PdfCommon.Initialize("XXXXXXX", PdfiumPath);

            var doc = Patagames.Pdf.Net.PdfDocument.Load(DocumentPath);

            List<LayerInfo> LayerInfos = new List<LayerInfo>();

            Patagames.Pdf.Net.BasicTypes.PdfTypeDictionary root = doc.Root;
            Patagames.Pdf.Net.BasicTypes.PdfTypeDictionary oc_prop = root["OCProperties"] as Patagames.Pdf.Net.BasicTypes.PdfTypeDictionary;
            Patagames.Pdf.Net.BasicTypes.PdfTypeArray ocgs = oc_prop["OCGs"] as Patagames.Pdf.Net.BasicTypes.PdfTypeArray;


Of course, real licence is not XXXXXXX.
Exception occur at line : Patagames.Pdf.Net.BasicTypes.PdfTypeDictionary root = doc.Root;

Code:
Patagames.Pdf.Net.Exceptions.NoLicenseException
  HResult=0x80131500

Well, you trying to get access to the document's internals: Document.Root for example.
This functionality is not available in the LITE version of SDK, but seems you are initializing it by the key for LITE version.

if you don't know which type of key you are using, please provide it to support@patagames.com to check.

Indeed, that may be the reason. I didn't pay attention to which functionnalities are available to which licensing mode.

As it's the first time I try to access the doc internals, I did not encounter the issue before.

I'll have a look at the full license

To test the the full functionality you can switch back to the trial mode by removing your key from initialization .

Thanks Paul for the info.
So my post title is wrong, it's not an environment issue but a licensing issue.
Not sure if it's worth keeping this thread in the support forum.
