Nifty C# Templates

New C# class, interface, record, enum, test and controller files with the right namespace, plus namespace syncing.

Maintained. No sign-in. No telemetry. Works in VS Code, Cursor, Windsurf, VSCodium and other editors that use Open VSX.

Features

Right-click the Billing folder, New C# Class, type a name in plain words and get InvoiceNumberGenerator with the folder's namespace

A new class in Services/Billing with the matching namespace

An exception class with the three standard constructors

Namespaces synced after moving files into a new folder

Right-click → New C# → Class (or Interface, Record, Enum) in the Explorer, type a name, done.
The namespace is always right. It's built from the nearest project's RootNamespace (or the project name) plus the folder path: a file in Shop.Api/Services/Billing gets namespace Shop.Api.Services.Billing;.
Modern by default. File-scoped namespaces (namespace X;) for .NET 6+ and C# 10+, block namespaces for older projects.
More templates under New C# File…: record struct, struct, static class, abstract class, exception (with the three standard constructors), xUnit test class, NUnit test class and ASP.NET Core API controller.
Naming conventions applied. repository becomes IRepository for interfaces, NotFound becomes NotFoundException, Orders becomes OrdersController, and Calculator becomes CalculatorTests.
Sync Namespace with Folder. Moved files around? Right-click a file or folder to fix every namespace to match its location.
Works without C# Dev Kit, including in Cursor, Windsurf and VSCodium.
Works in the browser on vscode.dev and github.dev.
