• Project wizard — webview UI with theme-aware styling, real-time name/path validation, recent projects, recommended (★) and LTS framework badges, full keyboard navigation.
• Every modern .NET template — Console, Class Library, Web API, MVC, Blazor (Server / WebAssembly), Worker Service, MAUI, Razor Class Library, gRPC Services, .NET Aspire (aspire, aspire-starter), test projects (xUnit, NUnit, MSTest), and more.
• Multi-project Clean Architecture scaffold — Domain, Application, Infrastructure, WebApi with the correct <ProjectReference> graph and conventional folders.
• Multi-project DDD scaffold — five-project layout with a dedicated SharedKernel, plus aggregate / value-object / specification folders.
• Add project to solution — pick a template + framework, attach to the current .sln.
• Fail-fast command sequencing — a failed dotnet new aborts the chain with a single clear error instead of cascading into "could not find project" noise.

Create Class, Create Interface, Create Struct, and Create Record read <TargetFramework> from the nearest .csproj and emit code that matches your project's actual C# language level.

On .NET 6+ (modern templates):

namespace Acme.Domain.Orders;

internal class Order
{
}

namespace Acme.Domain.Orders;

public sealed record Order(Guid Id, string CustomerName);

On net5.0 / netstandard* / netcoreapp* the classic block-namespace template is used so older codebases stay consistent.

Open any C# file, press Ctrl+., and pick from:

• Insert: Result<T, E> — railway-oriented success/failure type
• Insert: Option<T> — null-safe optional value
• Insert: Generic Repository — IRepository<T> + base implementation
• Insert: CQRS handler — IRequest<T> + IRequestHandler<T>
• Insert: Specification — composable predicate pattern
• Insert: Fluent Builder — chainable construction with validation
• Insert: Unit of Work — transactional aggregate of repositories

Each snippet is a fully-formed, modern C# implementation — not a TODO comment.

Run C# Toolbox: Quick Add NuGet Package, type a few letters, pick the .csproj to add it to. Curated default list of 26 popular packages including:

Serilog · Polly · MediatR · FluentValidation · AutoMapper · Mapster · Refit · MassTransit · Microsoft.EntityFrameworkCore · Npgsql · MongoDB.Driver · Hangfire · Quartz · NodaTime · OpenTelemetry · Swashbuckle · FluentAssertions · NSubstitute · Bogus · BenchmarkDotNet · …

Edit the list any time via csharp-snippet-productivity.nuget.popularPackages in your settings.

Run C# Toolbox: Analyze Solution to print a project-reference graph to the C# Toolbox Output channel and surface:

• Circular project references
• Orphan references (csproj-to-csproj entries pointing at non-existent projects)
• Project-by-project dependency lists

Useful before a refactor or when onboarding to a new codebase.

Tagged single-line comments are coloured automatically — no extra extension needed. 14 default tags:

All tags are configurable via csharp-snippet-productivity.tags.

• General productivity — cw, cwi, prop, func, try, class, ctor, instantiate, lst, dic, enum, switch, for, foreach, …
• Modern C# 11 / 12 / 13 — collection expressions, primary constructors, params collections, raw string literals, required members, list patterns, file-scoped types, UTF-8 string literals, generic attributes, static abstract members, default lambda parameters, inline arrays, ref readonly parameters.
• Architectural patterns — Result / Either, Option / Maybe, generic Repository, CQRS handler, Specification, Fluent Builder, Unit of Work, lightweight Mediator, Minimal API endpoints & route groups.
• GoF design patterns — Singleton, Factory Method, Adapter, Observer (commented reference implementations).
• XML documentation — full xml-summary / xml-remarks / xml-returns / xml-param / xml-typeparam / xml-exception / xml-see / xml-list / … set.

Full catalog with prefixes and expansions: docs/SNIPPETS.md.

All commands are also reachable via Ctrl+Shift+P. Default chord shortcuts:

• Ctrl+Alt+/ then p — Create Project
• Ctrl+Alt+/ then c — Create Class
• Ctrl+Alt+/ then i — Create Interface
• Ctrl+Alt+/ then r — Create Record
• Ctrl+Alt+/ then s — Create Struct
• Ctrl+Alt+/ then a — Add Project to Solution
