Professional REST API design with ASP.NET Core and WebAPI

This project is an example of lightweight and extensible infrastructure for building RESTful Web API with ASP.NET Core.

This example contains a number of tricks and techniques which I've learned while building APIs in ASP.NET Core.

Awesome SQL Code Review Tools for Developers

Today we are going to look into some of the tools that can help you in reviewing SQL code. These tools will assist in a variety of domain that is related to SQL such as code analysis, formatting, refactoring, and code documentation. 

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

PTVS offers an advanced IDE experience for general scripting, web programming, and technical computing. 

یک نکته‌ی تکمیلی: محدودیت بافر IAsyncEnumerable

اگر بیش از 8192 رکورد را به صورت IAsyncEnumerable بازگشت دهیم، خطای زیر ظاهر خواهد شد:

برای تنظیم یا تغییر آن می‌توان از خاصیت MvcOptions.MaxIAsyncEnumerableBufferLimit در برنامه‌های ASP.NET Core استفاده کرد.

Here are some of the reasons why nullable reference types are less than ideal:

• Invoking a member on a null value will issue a System.NullReferenceException exception, and every invocation that results in a System.NullReferenceException in production code is a bug. Unfortunately, however, with nullable reference types we “fall in” to doing the wrong thing rather than the right thing. The “fall in” action is to invoke a reference type without checking for null.
• There’s an inconsistency between reference types and value types (following the introduction of Nullable<T>) in that value types are nullable when decorated with  “?” (for example, int? number); otherwise, they default to non-nullable. In contrast, reference types are nullable by default. This is “normal” to those of us who have been programming in C# for a long time, but if we could do it all over, we’d want the default for reference types to be non-nullable and the addition of a “?” to be an explicit way to allow nulls.
• It’s not possible to run static flow analysis to check all paths regarding whether a value will be null before dereferencing it, or not. Consider, for example, if there were unmanaged code invocations, multi-threading, or null assignment/­replacement based on runtime conditions. (Not to mention whether analysis would include checking of all library APIs that are invoked.)
• There’s no reasonable syntax to indicate that a reference type value of null is invalid for a particular declaration.
• There’s no way to decorate parameters to not allow null.
