I found an application in C# to print with Dymo 550..I use I have an error but I don't know the cause:

Error	CS0012	The type 'Object' is defined in an assembly that is not referenced. You must add a reference to assembly 'netstandard, Version=, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'.	WPFSDKSample	C:\Users\VDS\Desktop\cartella\DCD-SDK-Sample-master\WPF\WPFSDKSample\ViewModels\MainViewModel.cs	22	Active

I write my code, I solved problem above adduing library but I have a doubt:

using DymoSDK.Implementations;
using Microsoft.Win32;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;

namespace WPFSDKSample.ViewModels
    public class MainViewModel : BaseViewModel
        DymoSDK.Interfaces.IDymoLabel dymoSDKLabel;
        public MainViewModel()
            dymoSDKLabel = DymoLabel.Instance;
            var Printers = DymoPrinter.Instance.GetPrinters();
            var TwinTurboRolls = new List<string>() { "Auto", "Left", "Right" };
        /// <summary>
        /// Open a Dymo label file and load the content in the instance of the class
        /// Get the preview image of the label
        /// Get the list of object names
        /// </summary>
        private void OpenFileAction()
            OpenFileDialog openFileDialog = new OpenFileDialog();
            openFileDialog.Filter = "DYMO files |*.label;*.dymo|All files|*.*";

            if (openFileDialog.ShowDialog() == true)
                var FileName = openFileDialog.FileName;
               // DymoSDK.App.Init();
                //Load label from file path
                //Get image preview of the label
                //Load image preview in the control 
                var ImageSourcePreview = LoadImage(dymoSDKLabel.Preview);
                //Get object names list
                var LabelObjects = dymoSDKLabel.GetLabelObjects().ToList();
        /// <summary>
        /// Print the current loaded label using the selected printer name
        /// </summary>
        private void PrintLabelAction()
            int copies = 1;

            if (SelectedPrinter != null)
                //Send to print
                if (SelectedPrinter.Name.Contains("Twin Turbo"))
                    int rollSel = SelectedRoll == "Auto" ? 0 : SelectedRoll == "Left" ? 1 : 2;
                    DymoPrinter.Instance.PrintLabel(dymoSDKLabel, SelectedPrinter.Name, copies, rollSelected: rollSel);
                    DymoPrinter.Instance.PrintLabel(dymoSDKLabel, SelectedPrinter.Name, copies);

                //If the label contains counter objects
                //Update counter object and preview to show the incresead value of the counter
                var counterObjs = dymoSDKLabel.GetLabelObjects().Where(w => w.Type == DymoSDK.Interfaces.TypeObject.CounterObject).ToList();
                if (counterObjs.Count > 0)
                    foreach (var obj in counterObjs)
                        dymoSDKLabel.UpdateLabelObject(obj, copies.ToString());
        /// <summary>
        /// Update the object value using the object name selected
        /// </summary>

I don't know c#, I don't understand if Selected Printer is a var o an objectof a library..because I have errore where is written SelectedPrinter

What I have tried:

I noticed that my program have problem to see in reference Microsoft.Office.Interop.InfoPath.SemiTrust

the message is clear: 'Object' is defined in an assembly that is not referenced.

I solved that error, but I have problems with variables;

It even tell you which reference and version to use - You must add a reference to assembly 'netstandard, Version=, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'.

Nobody has any idea what you mean by "now I have a problem with variables"? What variables? What error messages?
