Hello everyone, I have used my knowledge of VB to create PDF in Web pages on the fly.
It is a unique example that includes everything that is allowed to use the web examples.
Unfortunately, I could not get it from entering images in the PDF, as I returned the following error
BC30652: This requires a reference to assembly 'WindowsBase, Version = 3.0.0.0, Culture = neutral, PublicKeyToken = 31bf3856ad364e35' containing the type 'System.Windows.Point'. Add one to the project.And I do not know the solution
To run the example you must have a file "PdfSharp-WPF.dll" in the BIN directory. Remember that if a virtual directory, the folder BIN going in the server root.
(.../wwwroot/BIN/PdfSharp-WPF.dll)
Without more, the example
