رهانش EF Core 8 Preview 4: Primitive collections and improved Contains

The fourth preview of Entity Framework Core (EF Core) 8 is available on NuGet today!


Basic information

EF Core 8, or just EF8, is the successor to EF Core 7, and is scheduled for release in November 2023, at the same time as .NET 8.


EF8 previews currently target .NET 6, and can therefore be used with either .NET 6 (LTS) or .NET 7. This will likely be updated to .NET 8 as we near release.


EF8 will align with .NET 8 as a long-term support (LTS) release. See the .NET support policy for more information.

ساخت Custom Tool سفارشی در Visual Studio 2015
I have found a few descriptions in the net how to write a Custom Tool (Single File Generator) for Visual Studio but - mainly - the registration process had been an obstacle for me. Finally, I have come to a good point in my learning curve, and I am writing it up here all together for the community.

هر برنامه نویس یک خود آموخته است

 There are many ways to become a programmer beside getting a computer science degree. If you’re on that less conventional path, you may be wondering what you should do to catch up to people who do have a degree. How can you compete with someone who spent many years in a classwork learning about computers and programming?

بازخوردهای دوره
مثال - نمایش درصد پیشرفت عملیات توسط SignalR
- برای فراگیری کار با ASP.NET Web API از اینجا شروع کنید.
- در کل هیچ نیازی نیست تا این پروژه از نوع Web API باشد یا وابستگی Web API به آن اضافه شود (این فقط یک مثال بود؛ جهت بیان یک مفهوم یا عملکرد).
- همینقدر که DownloaderController را با یک کنترلر ASP.NET MVC هم جایگزین کنید کار می‌کند. فقط باید مسیر جدید را در فراخوانی‌های ای‌جکسی اصلاح کنید.

مقدمه ای بر Spark برای توسعه دهندگان دات نت

Spark is an open source computing framework for Big Data, and it’s becoming increasingly popular, especially in machine learning scenarios. In this article I’ll describe how to install Spark on a machine running a Windows OS, and explain basic Spark functionality from a .NET developer’s point of view.
