Simple Todo App with Blazor Server and Material Blazor

In order to make my journey in C# more interesting, I insert small projects where I can learn new things. The new target is now Blazor Server, a very interesting Web Technology from Microsoft.

I am trying to find small things to learn and add them to a bigger project later this year, perhaps.
My main tutors on the net were Tim Corey, and maybe Nick Chapsas. You can search them on youtube, they have great content.

The new application I have created is a regular todo app which uses:
- blazor server
- material design https://www.matblazor.com/
- a simple list (no database)

Prerequisites:
- asp.net core 3.1 installed on your machine
- intermediate C# and html

Code is under:
https://github.com/zoltanhalasz/TodoList_BlazorServer.git

The application is live: https://todolist-blazorserver.zoltanhalasz.net/todos

You can add material design to a blazor server project:
1.Install-Package MatBlazor
2.Add @using MatBlazor in main _Imports.razor
3.add to _Host.cshtml (head section)
<script src="_content/MatBlazor/dist/matBlazor.js"></script>
<link href="_content/MatBlazor/dist/matBlazor.css" rel="stylesheet" />

The toaster is added to the todo page: see instructions at: https://www.matblazor.com/Toast

I will explain some of the code and application below.

A. The main model class for the todos:


public class TodoModel
{
public int Id { get; set; }

public string Todo { get; set; }

public DateTime Deadline { get; set; }

public bool IsCompleted { get; set; }

}

B. The layout:
