Many programmers wonder whether they will still be hired as they enter their golden years. If you are a programmer and have been working for more than a few years, I won’t be surprised if thoughts have gone through your head about whether you will still be hireable as you approach your forties and fifties. Don’t worry, you are not alone. Traditionally, programming has been looked upon as an industry for young...

Dispose and Finalize are two methods you often use to release resources occupied by your .NET and .NET Core applications running in the context of the CLR. Most importantly, if you have unmanaged resources in your application, you should release the resources occupied by such resources explicitly. Due to the non-deterministic nature of finalization and because finalizers are costly in terms of performance, the Dispose method is used much more frequently...

The following are a set of best practices for using the HttpClient object in .NET Core when communicating with web APIs. Note that probably not all practices would be recommended in all situations. There can always be good reasons to break from a certain practice. This list is not supposed to be exhaustive and will probably be edited over time. All code examples are in C#. Manage HttpClient instances with HttpClientFactory HttpClient implements IDisposable....

.NET has a large number of built in exceptions. However, there maybe times when none of the built exceptions seem adequate for your particular scenario and you will need to create your own custom (AKA “user defined”) exception. This post focuses on a discussion of how to create custom exceptions in .NET. The different types of built in .NET exceptions, exception handling, throwing, and more general exception related best practices will...

Code Generation Code generation is a great way to apply patterns consistently across a solution or to create multiple similar classes based on some outside input file, or even other classes in the same solution. The tooling has changed over the years, but the result is the same… a lot of code that I don’t have to write by hand, or update when patterns change and evolve. I’ve been generating source code...

If you’re anything like me, you’ve looked for ways of making your applications faster. In this article, I’ll show you a somewhat unknown class in the .NET framework that makes lazy creation of objects easy to do and thread safe. The Old Way Before we get to the fun stuff, let’s take a look at how you might try to do these things without .NET’s Lazy<T> classes. Typically when you design a class,...

As we aware that framework .net core 2.1 is now under LTS (Long Term Support) releases. So, this framework is more stable and may use to create a large application. When we talk about web application, security is a major concern. In this article, I have explained about 10 points that need to consider before start application development. In this article, I will cover the following points: ...

SQL Server performance tuning can seem overwhelming when you don’t know where to start. In this article Robert Sheldon explains 9 best practices for performance tuning. SQL Server is a powerful and feature-rich database management platform that can support a wide range of applications, but if queries are not performing well or workloads are running into deadlocks, latency issues, and other disruptions in service, no one will care about how good...

Monitoring SQL Server for performance is a critical part of a DBA’s job. In this article, Edward Pollack explains some of the SQL Server performance monitor data and how to collect it. Windows collects a wide array of useful metrics that can be used to measure the performance of the SQL Server service. By default, this data is available but not collected or retained in SQL Server. Therefore, it falls to...

In C#, reference types can be assigned null values. This is something that developers will have to live with until they use classes to create software. Unfortunately, the folks at Microsoft cannot simply disallow null assignment to reference variables at compile time, because that would break the codebase of almost every project. Returning Null is bad practice What is actually wrong with returning a null reference from the method? Let’s take a look...

I've recently gotten into using Docker in my development cycle and I'm really enjoying how much of a wonderful tool it is. One thing that always used to be a pain was setting up a development server to run SQL Server. Now with Docker, I can just spin up a Docker container and I instantly have a SQL Server ready to go. I recently wrote a blog on Getting Started with...

In the context of helping the teams at Criteo to clean up our code base, I gathered and documented a few C# anti-patterns similar to Kevin’s publication about performance code smell. Here is an extract related to good/bad memory patterns. Even though the garbage collector is doing its works out of the control of the developers, the less allocations are done, the less the GC will impact an application. So the...

C# has a feature, String Interpolation, to format strings in a flexible and readable way. The following example demonstrates the way how we usually output a string when we have data beforehand then pass data to the template string. var name = "April"; var dob = new DateTime(2000, 4, 10); Console.WriteLine($"Her name is {name} and her birthday is on {dob:MM/dd/yyyy}, which is in {dob:MMMM}."); // Console Output: // Her name is April and sher birthday...

The other day at work I ran into an attribute I hadn't heard about, the [Conditional] attribute. In this post I start by describing conditional compilation using pre-processor directives like #if, and then introduce the [Conditional] attribute, and describe how it differs to using #if. Conditional compilation with #if With the release of .NET Core 5 years ago (has it really been that long?!) the need to multi-target .NET libraries and applications...

IP-адрес (v4) состоит из 32-бит. Любой уважающий себя админ, да и вообще айтишник (про сетевых инженеров молчу) должен уметь, будучи разбуженным среди ночи или находясь в состоянии сильного алкогольного опьянения, правильно отвечать на вопрос «из скольки бит состоит IP-адрес». Желательно вообще-то и про IPv6 тоже: 128 бит. Обстоятельство первое. Всего теоретически IPv4-адресов может быть: 232 = 210*210*210*22 = 1024*1024*1024*4 ≈ 1000*1000*1000*4 = 4 млрд. Ниже мы увидим, что довольно...

We are going to have a look at the steps you need to take to publish an ASP.NET Core application. Then, we are going to have a look on how to set this website up in IIS. Locating the SPA Static Files In-order for the ASP.NET Core application to render the React static files, we need to specify the path for these files. When we say the React static files, we mean...
