Entity Framework Core 7 (EF7) Preview 7 has shipped with support for several new interceptors, as well as improvements to existing interceptors.
یک نکتهی تکمیلی: محدودیت بافر IAsyncEnumerable
اگر بیش از 8192 رکورد را به صورت IAsyncEnumerable بازگشت دهیم، خطای زیر ظاهر خواهد شد:
‘AsyncEnumerableReader’ reached the configured maximum size of the buffer when enumerating a value of type ‘<type>’. This limit is in place to prevent infinite streams of ‘IAsyncEnumerable<>’ from continuing indefinitely. If this is not a programming mistake, consider ways to reduce the collection size, or consider manually converting ‘<type>’ into a list rather than increasing the limit.
برای تنظیم یا تغییر آن میتوان از خاصیت MvcOptions.MaxIAsyncEnumerableBufferLimit در برنامههای ASP.NET Core استفاده کرد.
In Defense of Lazy Loading
I don’t know how this happened but for the last couple years (at least), whenever I read an author who writes about ORMs, I often see a sentiment like this: “ORMs are fine, just make sure you disable this pesky feature called Lazy Loading”.
It’s like this feature is not even needed and only brings confusion and performance issues to everyone who chooses to use it. Well, as you may guess from the title of this article, I disagree with this point of view completely.

Follow along in this free course as I show you how to create an application in C# from idea through the finished product. Everything is shown on screen and in great detail. Learn how to use SQL databases, CSV text files, custom events, Linq, Lambda expressions, emailing, and more. Everything you learn will be in context of a real application.
.NET 7.0's Performance Improvements with Dynamic PGO are Incredible
In this short video Rowan takes us through a different approach to generating keys in Entity Framework 7 using sequences. This approach is interesting in cases of large INSERT batches primarily because keys are all fetched beforehand.
Now you can upgrade any .NET application to the latest version of .NET inside of Visual Studio! We are happy to introduce it as a Visual Studio extension and will upgrade your .NET Framework or .NET Core web- and desktop apps. In this video, Olia shows you how to get the extension and start to update your projects to the latest version of NET in minutes.
In the .NET framework 4+, there is enhanced support for parallel programming, including new class library types, Tasks, Parallel For, Parallel Linq, and concurrent collections. Check out some of these features here.
News
- As a site visitor, I can read current news on the home page.
- As a site visitor, I can access old news that is no longer on the home page.
- As a site visitor, I can email news items to the editor. (Note: this could just be an email link to
- the editor.)
- As a site a site editor, I can set the following dates on a news item: Start Publishing Date, Old
- News Date, Stop Publishing Date. These dates refer to the date an item becomes visible on the site (perhaps next Monday), the date it stops appearing on the home page, and the date it is removed from the site (which may be never).
- As a site member, I can subscribe to an RSS feed of news (and events? Or are they separate?).
- As a site editor, I can assign priority numbers to news items. Items are displayed on the front page based on priority.
Learn to use LINQ to simplify the process of coding and querying in C# and Visual Basic. LINQ Succinctly will guide you through the process, from conceptual understanding to practical implementation. With the help of author Jason Roberts, you will be streamlining your coding and querying practices in no time.
