MY ARTICLES:
Pass rollingInterval to the file sink and Serilog starts a new file on that schedule: .WriteTo.File("logs/log.txt", rollingInterval: RollingInterval.Day) produces log20260824.txt, log20260825.txt, and so on. Two more options decide how long that stays manageable....
As a C# developer, you might have overlooked the ModuleInitializer attribute introduced in version 9 of the language. This attribute is a hidden gem in the extensive BCL APIs and designates a method that the runtime should first invoke when loading the assembly....
IdentityUser gives us a user with a name, an email, a password hash and a lockout state, and no place to put a column of our own. The fix is to subclass it: ApplicationUser : IdentityUser, our properties on the subclass, and ApplicationUser everywhere the framework...
In this article, we will explore different techniques for sorting a list. A common task we face as developers is the need to sort a collection of data. The C# language provides us with a variety of ways in which we can accomplish this task. To help us have a better...
In this article, we will learn about the categories of C# data types. We will deep dive into the differences between value types and reference types, what are they and what's the behavior of each type when instantiated, compared, or assigned. It's important to...
Traditionally, code generation in C# involved using external tools or templates to generate code before the compilation process, like the T4 template. However, with source generators, code generation becomes an integral part of the compilation itself. In this article,...
Dictionary<TKey, TValue> has no built-in method that merges dictionaries, so we merge them ourselves: with a foreach loop that copies every key-value pair into a new dictionary, or with LINQ methods such as Concat(), GroupBy(), ToLookup() and Union(). These...
NSubstitute is a mocking library for .NET that reads like plain C#: Substitute.For<IEmailService>() creates the mock, service.IsValid(x).Returns(true) configures it, service.Received().Send(x) verifies it. No Mock<T> wrapper, no .Object property, no lambda...
In this article, we will discuss the locking mechanism in C#. We will explain what locking is and why we need it. We will demonstrate and explain different ways how we can use the mechanism. [sc name="github"...
In this article, we are going to explain how to access the configuration when the application is starting and how to retrieve services like IConfiguration and IWebHostEnvironment in this new setup. [sc name="github"...
When creating applications, authenticating users and ensuring the security of user data is paramount. To accomplish this, we can either create a custom authentication solution or leverage a third-party solution. In this article, we'll learn about adding a user login...
In this article, we will learn how to split an entity into multiple tables in EF Core. This is a new feature that we can find in version 7.0 of Entity Framework Core. [sc name="github"...
XML deserialization turns an XML document into a C# object. We describe the shape we expect as a class, hand the document to XmlSerializer, and get back an object with its properties filled in. Without a class to map onto, the alternative is reading and parsing an XML...
Navigating the world of distributed systems and microservices in C#? Then we should appreciate the combination of the Saga Pattern and NServiceBus. This powerful pairing provides us with an efficient solution for coordinating long-running, distributed transactions in...
InvalidOperationException: Unable to resolve service for type 'X' while attempting to activate 'Y' means the dependency injection container was asked to build Y, found a constructor parameter of type X, and had no registration for X. The full message looks like this,...
Scrutor adds two things missing from .NET's built-in dependency injection container: assembly scanning, which registers all our services in one line instead of dozens, and decoration, which wraps a registered service with logging, caching, or validation without...
In this article, we will look at how we can efficiently randomize an array in C#. We'll explore several ways of achieving that and then we'll compare the performance of each approach. [sc name="github"...
In this article, we are going to explore the key differences between the Publish and Send methods in MediatR, a powerful .NET library for component communication. [sc name="github"...
When we want to pass data in Blazor from a parent component to a child component, we use parameters. Parameters are defined on the component class with the Parameter attribute. If we define the parameter in the child component but don't pass a parameter from the...
In this article, we will discuss the differences between EntityFramework Core and Dapper. EntityFramework Core and Dapper are .NET...
