یکی از مواردی که حین کار کردن با iTextSharp واقعا اعصاب خردکن است، طراحی نامناسب ثوابت این کتابخانه می‌باشد. برای مثال:



6 ثابت اول مربوط به گروه PageLayout هستند و 6 ثابت دوم به گروه PageMode ارتباط دارند و این کلاس پر است از این نوع ثوابت (این کلاس نزدیک به 3200 سطر است!). این نوع طراحی نامناسب است. بجای گروه بندی خواص یا ثوابت با یک پیشوند، مثلا PageLayout یا PageMode، این‌ها را به کلاس‌ها یا در اینجا (حین کار با ثوابت عددی) به enum‌های متناظر خود منتقل و Refactor کنید. مثلا:


مزیت‌ها:
- طبقه بندی منطقی ثوابت در یک enum و گروه بندی صحیح آن‌ها، بجای گروه بندی توسط یک پیشوند
- استفاده بهینه از intellisense در visual studio
- منسوخ سازی استفاده از اعداد بجای معرفی ثوابت خصوصا عددی (در این کتابخانه شما می‌توانید بنویسید PdfWriter.PageLayoutSinglePage و یا 1 و هر دو صحیح هستند؛ این خوب نیست. ترویج استفاده از اصطلاحا magic numbers هم حین طراحی یک کتابخانه مذموم است.)
- کم شدن حجم کلاس اولیه (مثلا کلاس PdfWriter در اینجا) و در نتیجه نگهداری ساده‌تر آن در طول زمان

 LINQ to Entities does not recognize the method 'System.String ToString()' method, and this method cannot be translated into a store expression.

 public Task<EditUserViewModel> GetUserByRoles(int id)
        {
            return _users.AsNoTracking()
                    .Include(a => a.Roles)
                    .Project(_mappingEngine)
                    .To<EditUserViewModel>()
                    .FirstOrDefaultAsync(a => a.Id == id);
           
               
        }

Resume Management project with React18, ASP.NET Core7 WebAPI, TypeScript and Entity Framework Core
In this video, we will create a Fullstack Resume Management project using React18, ASP.NET Core WebAPI  (.NET 7),TypeScript and Entity Framework Core. The focus of this project is to show you how you can build a Fullstack project from 0 to 100 and build a simple CRUD application with ASP.NET Core WebAPI .

C# 11 is the next version of C# coming in .NET 7, and it is introducing a warning wave that issues a warning when a type is declared with all lower-case letters. This is being done so that in the future the language can begin moving away from conditional keywords and instead use full on keywords instead. The warning is alerting customers to types that may become keywords in future versions. 

Over the last decade, Android's open platform has created a thriving community of manufacturers and developers that reach a global audience with their devices and apps. This has expanded beyond phones to tablets, cars, watches, TVs and more—with more than 2.5 billion active devices around the world. As we continue to build Android for everyone in the community, our brand should be as inclusive and accessible as possible—and we think we can do better in a few ways. 

We developers spend lot of our time reading code. We read code so that we know how to change it to implement a new feature, fix a bug, etc. It is much better to work in a code base where code is easy to read and understand.

One thing that can make code readable is good naming. Giving variables, classes, and methods good names makes code easier to read. 

To reduce allocations and memory usage when serializing Json.NET 8.0 adds a new IArrayPool interface. Json.NET is already very lean when it comes to allocations, working with raw characters on array buffers instead of allocated strings, but those buffers can easily grow large, and a new buffer is created each time JSON is read or written. IArrayPool allows array buffers to be reused, similar to connection pooling with a database, or thread pooling in .NET. 

JSIL is a compiler that transforms .NET applications and libraries from their native executable format - CIL bytecode - into standards-compliant, cross-browser JavaScript. You can take this JavaScript and run it in a web browser or any other modern JavaScript runtime. Unlike other cross-compiler tools targeting JavaScript, JSIL produces readable, easy-to-debug JavaScript that resembles the code a developer might write by hand, while still maintaining the behavior and structure of the original .NET code.  Demo
