Disconnected context was detected (excel with c#)

I have a problem when I throw my program. My program contsist to change a excel file, but when I try to do it, visual studio show me this missatge "Disconnected context was detected".

This is some parts of my code:

public static void read_file(string file, string dir, string pathOut, string pathLogOut)
{

    string[] words = file.Split('.');
    int LengthWord = words.Length;
    string fileFormat = words[LengthWord - 1];


        try
        {                   
            string fileDestiny = file.Replace(@"IN\\", "");
            Console.WriteLine(fileDestiny);

            System.IO.File.Copy(file, fileDestiny, true);
            FileAttributes attributes = File.GetAttributes(fileDestiny);
            File.SetAttributes(fileDestiny, FileAttributes.Normal);

            Excel.Application xlApp;
            Excel.Workbook xlWorkBook = null;
            Excel.Range range = null;

            var misValue = Type.Missing;//System.Reflection.Missing.Value;

            xlApp = new Excel.Application();
            xlApp.DisplayAlerts = false;
            xlWorkBook = xlApp.Workbooks.Open(fileDestiny, misValue, misValue,
                misValue, misValue, misValue, misValue, misValue, misValue,
                misValue, misValue, misValue, misValue, misValue, misValue);

            VBA.VBProject project = xlWorkBook.VBProject;
            VBA.VBComponents VBComponents = project.VBComponents;
            string filePath = null;
            xlApp.VBE.ActiveVBProject.VBComponents.Add(VBA.vbext_ComponentType.vbext_ct_StdModule).CodeModule.AddFromFile(@"C:\IN\RemplazoString.bas");
            xlApp.Run("MACRO");

            }

            // Guardar y cerrar
            Excel.XlFileFormat FileFormat = xlWorkBook.FileFormat;
            xlWorkBook.SaveAs(fileDestiny, FileFormat);
            xlWorkBook.Close();

            File.SetAttributes(fileDestiny, attributes);

            // liberar
            releaseObject(xlWorkBook);
            releaseObject(xlApp);

            IndexFile = IndexFile + 1;
            using (StreamWriter sw = File.AppendText(pathLogOut))
            {
                sw.WriteLine(IndexFile + "." + file + " --> Hecho");
            }
        }
        catch (Exception e)
        {
            Console.WriteLine("El fichero {0} no se guardo correctamente {1}", file, e.ToString());

    }
}

public static void releaseObject(object obj)
{
    try
    {
        System.Runtime.InteropServices.Marshal.ReleaseComObject(obj);
        obj = null;
    }
    catch (Exception ex)
    {
        Console.WriteLine("Unable to release the object(object:{0})", obj.ToString());
    }
    finally
    {
        obj = null;
        GC.Collect();
        GC.WaitForPendingFinalizers();
        GC.Collect();
        GC.WaitForPendingFinalizers();
    }
}

I have this error:

"Transition into COM context 0x86b848 for this RuntimeCallableWrapper failed with the following error: System call failed. (Exception from HRESULT: 0x80010100 (RPC_E_SYS_CALL_FAILED)). This is typically because the COM context 0x86b848 where this RuntimeCallableWrapper was created has been disconnected or it is busy doing something else.
