PDFsharp & MigraDoc Forum

Hi, i'm trying to set a password in a PDF document but the PdfReader method raise an exception:

The file or assembly 'Microsoft.Extensions.Logging.Abstractions, Version=8.0.0.2, Culture=neutral, PublicKeyToken=adb9793829ddae60' or one of its dependencies could not be loaded. The system cannot find the file specified.

My program is in VB.Net FrameWork 4.8.1
PdfSharp loaded from Nuget (PdfSharp-GDI 6.2.1)

Imports PdfSharp.Pdf
Imports PdfSharp.Pdf.IO

Public Sub AddPassword(ByVal FileName As String, ByVal Password As String)
Try
Dim Document As PdfDocument = PdfReader.Open(FileName, PdfDocumentOpenMode.Modify)
Dim SecuritySettings As Security.PdfSecuritySettings = Document.SecuritySettings
SecuritySettings.UserPassword = Password
SecuritySettings.OwnerPassword = Password
SecuritySettings.PermitAnnotations = False
SecuritySettings.PermitAssembleDocument = False
SecuritySettings.PermitExtractContent = False
SecuritySettings.PermitFormsFill = False
SecuritySettings.PermitFullQualityPrint = True
SecuritySettings.PermitModifyDocument = False
SecuritySettings.PermitPrint = True
Document.SecurityHandler.SetEncryptionToV2With128Bits()
Document.Save(FileName)
Catch Ex As Exception
LoadErrors(Ex.Message)
End Try
End Sub

The file "'Microsoft.Extensions.Logging.Abstractions.dll" should be in the same folder where PdfSharp-gdi.dll is.

Both DLLs are in the same folder.
More info:
EXE & DLL in VS2022.
The code showed below is part of a DLL that made a PDF file.
The DLL is a component library in .Net FW 4.8.1.
The PdfSharp is used to protect that file with a password.
The DLL is used in a WinForms .Net FW 4.8.1 proyect.

Cannot reproduce with the information you provide.

Please use the IssueSubmissionTemplate to make it replicable.

Hi. For some reason, the DLL doesn't copy all the referencies to the EXE proyect.
The DLL has the property 'Local Copy = True'.
Only happens when the PDFSharp is referenced in a DLL.
To solve the problem, i copied the PDFSharp-GDI, via NuGet, to the EXE proyect.
