Today we're going to discuss how small optimizations in the right places of the application can improve its performance. Imagine: we remove the creation of an extra iterator in one place, get rid of boxing in the other. As a result, we get drastic improvements because of such small edits.
In this topic, I will tell you how to dynamically parse and deserialize only part of the whole JSON document. We will create an implementation for .NET Core with C# as a language.
For example, we have the next JSON as a data source for the report. Notice that we will get this JSON in the runtime and at the compile step we don't know the structure of this document. And what if you need to select only several fields for processing?
Entity class from a symbolic algebra library:
When we are told “There is no thread” we can easily come to an opinion that it is impossible at ALL that asynchronous operation could create thread, but it would be wrong opinion. Simple code example proves the opposite.
Those who are easy to treat the sentence as the universal rule are easy to understand. They would like to simplify the subject and to cut amount of theory they should study and remember. Besides to many it is new level of knowledge to discover there is other layer of classes to manage async-operations behavior beside the Tasks and and SynchronizationContext is only one among them.
The title of the article is a question I was asked in an interview for a Middle position. In this article, we will look at Unity coroutines, what they are, and at the same time we will capture the topic of Enumerator \ Enumerable in C # and a little secret of foreach. The article should be very useful for beginners.
How can simple XML files processing turn into a security weakness? How can a blog deployed on your machine cause a data leak? Today we'll find answers to these questions, learn what XXE is and how it looks like.
Welcome all fans of clean code! Today we analyze the PascalABC.NET project. In 2017, we already found errors in this project. We used two static analysis tools (more precisely, plugins for SonarQube): SonarC# and PVS-Studio. Today, we analyze this project with the latest version of the PVS-Studio analyzer for C#. Let's see what errors we can find today, especially when our analyzer has become more advanced and got new features: it can find more exquisite errors and potential vulnerabilities.
Let's take a look at the list of information sources that can be useful for the C# / .NET developers. Our list includes blogs, repositories with source code, standards and accounts of developers who covers the deep aspects of the C# and .NET.
The .NET 6 turned out to be much-awaited and major release. If you write for .NET, you could hardly miss such an event. We also couldn't pass by the new version of this platform. We decided to check what interesting things we can find in the sources of .NET libraries.
XSS - or cross-site scripting - is one of the most common vulnerabilities in web applications. It has been on the OWASP Top 10 list (the list of the most critical security risks to web applications) for a while now. So let's figure out together how your browser can acquire and execute a script from a third-party website, and what this may lead to (spoiler: your cookies could get stolen, for example). And while we're at it, we'll talk about ways you can protect yourself from XSS.
