Capitalize on C# time⁠-⁠tested strengths with *instinctools

Bet on technologies that advance with your industry standards and make your infrastructure immune to disruptions and risks.

Cross-platform support

Build once, deploy everywhere. C# multi-platform development allows you to build cross-platform applications from a single codebase, saving you time and money on native development.

Strong typing
Thanks to its predictability and maintainability, C# code ushers in more structure into your applications. This makes it faster and easier for software engineers to spot and eliminate bugs early in the development.
Modern language features

Each version of C# takes in new features to support emerging workloads and software design practices. From collection expressions to default lambda parameters, the language evolves to simplify building innovative, future-proof applications.

Rich library support

As a part of the .NET framework, C# comes with a raft of canned features. Mobile apps, desktop apps, cloud-based services, or enterprise software — C# gives you a head start on any of these projects.

Great tooling

From user interface tools and frameworks to IDEs and testing tools, there is a slew of C# tools developers can call at a whim to simplify software development, facilitate testing, and build automation environments.

Versatility for various types of applications 

The technology enables you to target applications running on mobile platforms, desktop devices, enterprise servers, and microservices. No need to juggle tech stacks, just build on top of the .NET core.

Security and performance

With built-in mechanisms such as encryption libraries and type safety, C# helps developers catch app security threats early and validate user input, making your applications more secure and cyber-resilient.

Grow your business on a solid foundation of C# and .NET

Awards and recognition


What is C# best used for?

C# is a general-purpose language, which means it’s highly applicable across application domains. Thanks to inbuilt garbage collection, C# improves overall program stability — an edge especially important for large-scale, enterprise systems. C# rapid application development puts companies up for a quick start on their project, while C# backend development is a go-to option for building a simple, readable, and high-performance foundation for digital solutions.

You can also use .NET and C# mobile app development to develop native apps for the millions of Android, iPhone, and iPad devices around the world.

Is C# good for mobile development?

Due to its similarity with Java, C# mobile development is ideal for powering Android mobile applications. Along with C# Android app development, the language is compatible with iOS mobile development software, allowing you to implement native code for your mobile apps regardless of their platform. Moreover, Unity and C# mobile game development is one of the most widely used combinations for developing new titles. 

Can I use C# with HTML and CSS?

Yes, you can combine C# and .NET to develop fast and secure websites based on HTML5, CSS, and JavaScript.
