C#.NET for non-engineers.
The first course of "A Sr. Developer Course" courses. which contains:
1- C# Fundamentals for non-engineers.
2- DataBase for non-engineers.
3- Asp.NET WebForm for Non-engineers.
4- Application Architecture for no-engineers.
5- ASP.NET MVC for non-engineers.
6- Angular for non-engineers.
This is a course for who knows noting about C# and development if you know nothing about Array, variable, loop, and conditions you are in the right place.
at the end of this course, we will create one small university registration console application together.
You will learn in this course:
C#.NET
.NET Framework
Methods
Recursive methods
C# Primitive Types/Complex Types
conditions
switch case
Arrays
if statement
switch
loops
Creating a method
ref, out
enums
OOP/Object-oriented programing
Generics
Error handling
problem-solving
working with files
level: beginners to upper intermediate

Problem / solution format brings an easier understanding on how to build things, giving an immediate feedback. Starting from this idea, the blog post will present step by step how to build
a web application to store your ideas in an easy way, adding text notes, either from desktop or mobile, with few characteristics: run fast, save on the fly whatever you write, and be reasonably reliable and secure.
This blog post will implement just the backend, WebApi and the database access, in the most simple way. Next blog post will cover the front end, using Angular. Then, there will be an additional article on how to increase the performance and the security.
یک نکته‌ی تکمیلی: امکان تعریف مسیریابی صفحات، با استفاده از ویژگی Route
عموما مسیریابی‌های صفحات Blazor، به صورت زیر تعریف می‌شوند:
@page "/counter"
و اگر نیاز باشد تا این مسیر را در قسمت‌های دیگری هم ذکر کنیم (برای مثال در لینک‌ها و یا متد NavigateTo)، باید دقیقا همین مسیر و عبارت را در چندین قسمت برنامه تکرار کنیم. برای رفع این مشکل، با استفاده از ویژگی Route می‌توان مسیریابی فوق را به صورت زیر بازنویسی کرد:
@attribute [Route(Constants.CounterRoute)]
در این حالت می‌توان از مزیت تعریف مسیر مدنظر به صورت یک ثابت، به صورت زیر استفاده کرد:
public static class Constants
{
public const string CounterRoute = "/counter";
}و اگر در قسمت دیگری از برنامه نیاز به ارجاعی به آن بود، می‌توان همین رشته‌ی ثابت را مجددا مورد استفاده قرار داد:
NavigationManager.NavigateTo(Constants.CounterRoute);
