Dependency Injection + MVVM?

I followed a Tim Corey tutorial on Dependency Injection in WPF but he did not use MVVM just raw code behind. How hard would be to switch over to MVVM? I just want an app where I have a MainView, SettingsView, and a few other Views. He uses Interfaces, etc and I'm lost. :< What should I do?

BindModel with DateTimePicker

I have a simple WinForms Dapper ORM w/SQLite app I've written, everything works except binding to the DateTimePicker controls. My model:

namespace TaskMinder.Model;

public class Entry
{
    public int Id { get; set; } = 0;
    public DateTime EntryDate { get; set; }
    public DateTime EntryTime { get; set; }
    public string EntryData { get; set; } = string.Empty;
}

namespace TaskMinder.Model;

public class Entry
{
    public int Id { get; set; } = 0;
    public DateTime EntryDate { get; set; }
    public DateTime EntryTime { get; set; }
    public string EntryData { get; set; } = string.Empty;
}

My method:

    private void BindModel(Entry model)
    {
        NewEntryDatePicker.DataBindings.Add("Value", model, "EntryDate", true, DataSourceUpdateMode.OnPropertyChanged);
        NewEntryTimePicker.DataBindings.Add("Value", model, "EntryTime", true, DataSourceUpdateMode.OnPropertyChanged);
        NewEntryTextBox.DataBindings.Add("Text", model, "EntryData", true, DataSourceUpdateMode.OnPropertyChanged);
    }

    private void BindModel(Entry model)
    {
        NewEntryDatePicker.DataBindings.Add("Value", model, "EntryDate", true, DataSourceUpdateMode.OnPropertyChanged);
        NewEntryTimePicker.DataBindings.Add("Value", model, "EntryTime", true, DataSourceUpdateMode.OnPropertyChanged);
        NewEntryTextBox.DataBindings.Add("Text", model, "EntryData", true, DataSourceUpdateMode.OnPropertyChanged);
    }

What am I doing wrong? Thank you in advance.

❔ Bytes to UInt64

I am having a issue trying to turn the hex output to ulong, (UINT64). I keep getting 6687895829614943646 from 5CD02DD2B303DD9E I know 5CD02DD2B303DD9E should be 11447309898705915996 since my hex editor is right. I am using Little Endian. Any help would be appreciated, thank you. Here is my code:
