.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.

Roslyn-based library that offers more than 50 analyzers and more than 70 refactorings for C#.  

Today, we are glad to release .NET 6 Preview 2. It includes new APIs, runtime performance improvements, and early builds of .NET MAUI. It also includes builds for Apple Silicon, which were missing for Preview 1. 

Finally, the backend runs on .NET Core runtime by default on macOS and Linux, instead of the Mono runtime. Moving to .NET Core runtime delivers noticeable performance improvements, a lower memory footprint, and multithreaded NuGet restore. 

Today, we are releasing .NET 5.0 Preview 8. The .NET 5.0 release is now “feature complete”, meaning that very nearly all features are in their final form (with the exception of bug fixes still to come). Preview 8 is, appropriately, the last preview. We plan on releasing two go-live release candidates before the final .NET 5.0 release in November. This post describes a selection of features across the .NET 5.0 release.

سپس کلید پکیج  را زده تا پکیج مورد نظر آماده شود. دقت داشته باشید که بعد از انتخاب کامپایلر متلب، حجم پکیج نزدیک به 400 مگابایت خواهد شد. پکیج مورد نظر بصورت یک فایل exe فشرده خواهد شد.
معمولا پکیج شامل فایل‌های زیر باید باشد :

بعد از طی مراحل فوق نوبت به تیم برنامه‌نویسی دات نت می‌رسد. بعد از دریافت پکیج از تیم برنامه‌نویسی متلب در صورتیکه بر روی سیستم هدف کامپایلر متلب و یا خود متلب نصب نیست باید از داخل پکیج این کامپایلر نصب شود.
دقت داشته باشید که ورژن کامپایلر بر روی سیستم باید با ورژن پکیج دریافتی یکی باشد.
در VS یک پروژه کنسول ایجاد کنید و از فولدر پکیج پروژه دریافتی در زیرفولدر distrib فایل makeSqr.dll را به رفرنس برنامه VS اضافه کنید.
در ادامه از مسیر نصب کامپایلر فایل MWArray.dll را هم به رفرنس پروژه اضافه کنید. این فایل جهت تبادل داده اپلیکیشن با کامپایلر متلب مورد استفاده قرار می‌گیرد.

            MWNumericArray output = (MWNumericArray)result[0];
            Console.WriteLine(output);

Introducing QOI — the Quite OK Image format. It losslessly compresses RGB and RGBA images to a similar size of PNG, while offering a 20x-50x speedup in compression and 3x-4x speedup in decompression. All single-threaded, no SIMD. It's also stupidly simple.

Compared to stb_image and stb_image_write QOI offers 20x-50x faster encoding, 3x-4x faster decoding and 20% better compression. It's also stupidly simple and fits in about 300 lines of C.
