I have a problem when I try to generate a pdf file in Azure. When I test the code localy everything works fine. But when I deploy my server onto Azure I get the error that you can see in the image. The error occurs when the RenderDocument method is being called. I don't know what the problem is. Am I doing anything wrong?

I use the NuGet package PDFsharp-MigraDoc-gdi (1.50.5147).

The code I'm using is:
using test_api.Model;
using MigraDoc.DocumentObjectModel;
using MigraDoc.DocumentObjectModel.Shapes;
using MigraDoc.DocumentObjectModel.Tables;
using MigraDoc.Rendering;
using PdfSharp.Pdf;
using System.IO;

namespace test_api.Services
{
public class PDFGenerator
{
private Document document;
private TextFrame generalFrame;
private Table table;
PdfDocumentRenderer renderer;

private Color TableBorder = Colors.Black;
private Color TableGray = Colors.LightGray;
private Factuur factuur;
MemoryStream stream;

public void GeneratePDF(Factuur factuur)
{
this.factuur = factuur;
// Create a new MigraDoc document
CreateDocument();
DefineStyles();
CreatePage();
FillContent();
this.renderer = new PdfDocumentRenderer();
renderer.Document = document;
renderer.RenderDocument();
stream = new MemoryStream();
renderer.PdfDocument.Save(stream,false);
}
public MemoryStream GetStream()
{
return stream;
}
private void CreateDocument()
{
this.document = new Document();
this.document.Info.Title = "test1";
this.document.Info.Subject = "test2";
this.document.Info.Author = "test3";
}
private void DefineStyles()
{
//Normal style
Style style = this.document.Styles["Normal"];
style.Font.Name = "Verdana";

style = this.document.Styles[StyleNames.Header];
style.ParagraphFormat.AddTabStop("16cm", TabAlignment.Right);

style = this.document.Styles[StyleNames.Footer];
style.ParagraphFormat.AddTabStop("8cm", TabAlignment.Center);

//Create new style called Table
style = this.document.Styles.AddStyle("Table", "Normal");
style.Font.Name = "Verdana";
style.Font.Name = "Times New Roman";
style.Font.Size = 9;

//Create new style called Titel

No, there is a deployment problem and not all assemblies required by MigraDoc/PDFsharp were published to the server.

But the error I get now I get when I try running it local. Is there a way to fix this error or do I need to go back to gdi and fix the other error somehow?

Fix this error by adding a reference to PresentationCore to your project.

I have add a reference to the Presentationcore. Now I get the error shown in the picture. Already addded a reference to the WindowsBase. I'm using asp.net core 2.2, I think it's just not possible to use the DispatcherObject in .net core or am I wrong?
