In contrast to the previous GlobalUsings.cs file, these global imports work on the MSBuild project level. For instance, when using, you’ll get the following namespaces imported: There is also a new project-level property called ImplicitUsings to add a set of common namespaces that depend on the SDK chosen in your project.

Just as with any other using directive, ReSharper and Rider will highlight any unused global using directive, so that you can keep your code clean and minimal: Remove redundant Global Using Directive Global using Console= Ĭonsole.MarkupLine($'Max input: ') Global usings also work in other variations, such as static usings and using aliases, which makes them really convenient to use the Math static class in computational code or to replace commonly used types with better implementations: // GlobalUsings.cs If you’re looking for a great test assertion library, remember, we had a great OSS PowerUps session with Dennis Doomen about Fluent Assertions ! This will let those namespaces be automatically imported in every project ending with the Tests postfix:

You can even go one step further, and define a with all the test-relevant namespaces, and create a in the root of your repository. With C# 10 you can use global using directives that the compiler will consider for the whole project: // GlobalUsings.cs At the same time, it can be very annoying if your file templates don’t have these included and you have to import them over and over again. How many times does your codebase contain the lines using System or using System.Linq? Among individual other namespaces, some are just very common to import in every file throughout your solution. Now, have fun and be amazed! Global Usings Psst! ReSharper and Rider support them both.

In this post we will look at the different ways the new global usings can help. Improvements and Optimizations for Interpolated Strings.NET team has implemented, and how ReSharper and Rider make it easy to adopt them in your codebase. Welcome to the third part of our series, where we take a closer look at the new C# language features the.
