In this article, we will dive into what hot reload is and how it revolutionizes our development workflow. We will review its features, origins, examples, and most importantly best practices. Let's start. What is Hot Reload Hot reload stands as a transformative feature...
In this article, we will learn how to force run a .NET application as an Administrator. We will do that by modifying the application manifest file of our application to illustrate the whole process. [sc name="github"...
Noda Time is an open-source date and time library for .NET that gives each kind of value its own type: Instant for a moment on the global timeline, LocalDate and LocalDateTime for calendar values, and ZonedDateTime when a time zone matters. Handling dates can be...
A query string is the ?name=value&name=value tail of a URL, and in C# we have six ways to build one. Four of them percent-encode the values for us. UriBuilder, the one most people reach for, does not. QueryHelpers.AddQueryString() is the short answer for an...
In this article, we will discuss the use of the strangler fig architectural pattern. While the design can be applied to any programming language, we will focus on C# here. [sc name="github"...
Managing files and directories is a fundamental aspect of many software development applications. In this article, we will learn C# file system manipulation using the Directory and DirectoryInfo classes. [sc name="github"...
In this article, we are going to learn how to read a string from a .resx file. While doing this, we are also going to understand what is going on under the hood. Additionally, we will follow some of the best practices on how to manage resource files, and lastly, offer...
In this article, we will delve into ASP.NET Core forms and how to add rows to them dynamically. We'll use razor pages to create the form and SQLite as our database. [sc name="github"...
When working with MediatR in .NET, we can often utilize its Pipeline Behavior. In this article, we'll examine a common warning related to the type TRequest that can occur while working with it, see why it appears, and how we can solve it. [sc name="github"...
To stop AutoMapper overwriting a destination value with a null from the source, add a condition to the mapping: .ForAllMembers(opts => opts.Condition((src, dest, srcMember) => srcMember != null)). Members whose source value is null are then skipped, and whatever...
In this article, we will look at keyed services - a new feature in .NET 8 that allows us to retrieve services by a given key. [sc name="github"...
The unit of work pattern groups every change a business operation makes and saves them together, in one transaction, so they all succeed or all fail. We will discover its advantages and disadvantages, and build an example implementation with Entity Framework Core....
In this article, we will discuss the recently added Table Per Concrete Type (TPC) inheritance mapping strategy in EF Core 7. In .NET applications, Entity Framework Core (EF Core) has transformed how we communicate with databases by linking object-oriented domain...
To find a substring while ignoring case in C#, pass a StringComparison value: source.Contains(needle, StringComparison.OrdinalIgnoreCase). Without that second argument, Contains() is case-sensitive, and there is no other switch that changes it. [sc name="github"...
A line break in C# is not one character. It is any of seven sequences, and ReplaceLineEndings() is the one method that matches all of them: text.ReplaceLineEndings("\n") normalises a mixed string in a single call. String.Replace() and Regex.Replace() also do the job,...
MediatR handles exceptions through IRequestExceptionHandler<TRequest, TResponse, TException>. We implement it once with open generics, register it in the container, and any exception thrown inside a handler is caught, logged, and turned into a response instead...
Convert.FromHexString() turns a hexadecimal string into a byte array in one line on .NET 5 and later. It accepts uppercase and lowercase digits, and it throws a FormatException for an odd length, a 0x prefix or any character that is not hex. In the rest of this...
In this article, we will explore refactoring dispensables in C#. We'll focus on identifying code smells and enhancing our code through practical refactoring techniques. [sc name="github"...
XPath is a path language for XML, and .NET exposes it through two methods on XmlNode: SelectSingleNode() returns the first node an expression matches, and SelectNodes() returns every one of them. An expression reads like a file path. /catalog/book walks down from the...
In this article, we'll look at TimeProvider - a new feature coming to C# 12 and .NET 8 that provides a built-in way to deal with and test time-dependent code. [sc name="github"...
