.NET 7 minimal API from scratch | FULL COURSE | clean architecture, repository pattern, CQRS MediatR

In this course I want to provide you a project structure and code organization to get you started with real .NET 7 minimal API projects. It's a full course on this topic where I start from creating and explaining the project structure, setting up different layers using EF Core, repository pattern, CQRS and MediatR. The biggest part of the video is however around the .NET 7 minimal API, taking you from the initial setup, explaining route handlers, implementing all CRUD operations and so on. Last but not least, this course walks you through the process of refactoring the .NET 7 minimal API so that it becomes readable, maintainable and scalable. At the end, you'll have a full project structure organized according to modern architectural patterns that you can take as a template for your own projects.

• نسخه بندی معنایی
• نسخه بندی استاندارد مایکروسافت

پس از باز شدن پنجره Version Manager پروژه‌های Solution جاری بارگذاری و  Assembly Version و File Version هر پروژه را می‌توانید به راحتی مشاهده و یا تغییر دهید.

اگر بخواهید بصورت خودکار بر اساس شمای انتخاب شده، نسخه نرم افزار را افزایش دهید، شمای نسخه بندی را انتخاب کنید. در دو زمان Build و یا Rebuild پروژه می توان نسخه را افزایش داد.

Semantic Versioning:

1. گزینه Semantic Versioning را از قسمت Version Style انتخاب کنید.
2. گزینه Increment Action قسمتی از نگارش که می‌خواهید شمای  نسخه بندی بر روی آن اعمال شود را مشخص می‌کند. که دو گزینه Build یا Revision وجود دارد
3. گزینه Increment Event زمان رویداد اعمال شمای انتخاب شده را مشخص می‌سازد.
4. تنظیمات را ذخیره و پروژه خود را Rebuild نمایید.
5. در پنجره Output نسخه جدید نشان داده می‌شود.

Making SQL Server run on Linux involves introducing what is known as a Platform Abstraction Layer (“PAL”) into SQL Server. This layer is used to align all operating system or platform specific code in one place and allow the rest of the codebase to stay opera 

Awesome collection of .NET Core Static Analyzers using the .NET Compiler Platform (Roslyn). A sample project along with Cake Script for Continuous integration is also included in this repository with some of Analyzers added through Nugget. 

Cryptography has crept into everything, from web browsers and email programs to cell phones, bank cards, cars and even into medical implants. Thus, an increasing number of people have to understand how crypto schemes work and how they can be used in practice. We wanted to create a book that teaches modern applied cryptography to readers with a technical background but without an education in pure mathematics.  

A Universal Windows Platform (UWP) app can run on any Windows-based device, from your phone to your tablet or PC

In this episode, Robert is joined by Phil Japikse for a chat about design patterns. Software design patterns have been around long before the MVC Framework gained momentum. Phil starts with a review of Robert C. Martin's (Uncle Bob) SOLID macronym. After building the proper foundation,he reviews several design patterns, their C# implementation and when and how they should be used in modern software development. 

The Microsoft Build Engine (MSBuild) is a platform for building applications. 

A Web standard that’s currently implemented behind Chrome’s Experimental Web Platform features flag, Background Fetch lets you handle large downloads in a browser programatically and then get notifications of their completion, even if the browser closes.
