Hey Node.js... have you tried .NET?

Easy-to-understand and familiar concepts

As a Node developer, you'll feel right at home with .NET and C#. Since .NET delivers similar features and functionality on any OS, you'll have no trouble at all getting started. C# supports callbacks, async, and easy access to web services via HTTP.

private DamageResult CalculateDamageDone()
{
    // Code omitted:
    //
    // Does an expensive calculation and returns
    // the result of that calculation.
}


calculateButton.Clicked += async (o, e) =>
{
    // This line will yield control to the UI while CalculateDamageDone()
    // performs its work.  The UI thread is free to perform other work.
    var damageResult = await Task.Run(() => CalculateDamageDone());
    DisplayDamage(damageResult);
};

// And that's it! This code cleanly expresses the intent of
// the button's click event, it doesn't require managing a background
// thread manually, and it does so in a non-blocking way

Asynchronous programming at scale with C#'s async and await

While Node.js uses a single threaded event loop model, ASP.NET is async and multi-threaded, making it better suited for CPU intensive workloads.

ASP.NET can utilize the full capabilities of your hardware. Instead of running 8 separate instances of Node.js process on your 8-core machine and adding a load balancer to handle routing requests, ASP.NET handles the synchronous portions of 8 requests simultaneously in one process.

C#'s mature and widely adopted async/await support allows you to write natural async code and avoid callback hell when adding logic retries, implementing exception handling, or diagnosing error stacks.

Open source, cross-platform, and vibrant ecosystem

The .NET open source ecosystem is governed by the .NET Foundation and your code is backed and supported by Microsoft. This gives you the best of both worlds - offering openness and speed while providing stability and governance from a company you trust. As a Linux, Mac, or Windows developer, you can be confident that your applications will be supported as they grow in years to come.

Performance where it matters

.NET is fast. Really fast! That means applications provide better response times and require less compute power.

The popular TechEmpower benchmark compares web application frameworks with tasks like JSON serialization, database access, and server side template rendering - .NET performs faster than any other popular framework.

Enterprise-ready, secure, and cross-platform standard libraries

With C#, you can use a vast standard set of enterprise-ready, secure, and well-documented libraries. All your core needs are met out-of-the-box without any extra package downloads.

Native modern apps using existing skills, teams, and code

C# can be used for web, mobile, desktop, games, machine learning, and IoT applications. From Raspberry Pi to Xbox and Android to Apple Watches, .NET is on every platform.

Build your games with Unity or cross-platform mobile apps with .NET - all with exceptional quality, presentation, and a native look and feel on any platform.

Increased productivity through rich code editing in C#

Since C# is a statically typed language, more information about your code is known at design time. .NET's Intellisense feature is much more than "autocomplete" - it helps you identify and fix errors at design time instead of waiting for a full edit-build-run cycle in Node.js

Static typing also enables advanced code refactoring and understanding in tools you know and love like Visual Studio Code and Visual Studio.

Platform of choice for the top 100K websites

More websites have been developed with ASP.NET than Ruby, Java, Python, Node.js, and Go combined.

Why do companies like Stack Overflow, UPS, and Chipotle choose .NET? For better performance, increased flexibility, and higher compatibility.
