What is C#, and what is it used for?

C# is a programming language developed by Microsoft in 2000. It’s object-oriented, and it was designed to use the best features of C++ and Java. Today, it has a wide range of uses – but its main one is the development of server-side web apps and, sometimes, game development. ASP.NET, Microsoft’s server-side framework for dynamic web pages, uses C# – so you can use the language to create web services, web applications, and a website. Apart from that, some of the most popular game engines used in today’s gaming industry run on C# – such as Unity. Around a third of all modern games were built with Unity for a diverse audience numbering hundreds of millions of people. Plus, Unity provides exceptional support for VR platforms, such as the Valve Index or the Oculus Rift. Overall, C# has an extensive library providing plenty of high-level functionalities – more than C++ and Java.

What is C# particularly good for? When is it the right choice for a project?

There are plenty of reasons why a freelance C# developer is in high demand these days – for example, the fact that C# is an easy language to start with if you’re a junior software developer. It’s a high-level language, and while it’s in the same family of popular object-oriented languages as C++, Java, and C, it's easier to learn than most. Today, C# is frequently used for developing desktop and web applications. And seeing as it was created by Microsoft, it’s understandable why it’s still a go-to language for creating Microsoft apps. Also, it’s worth remembering that a programming language is easier to learn and master if it has a large community of developers – which is definitely the case with C#. However, the question of whether it’s right for your project depends on what you’re working on. Web development and desktop projects are routinely developed using C# because it’s a higher-level programming language. However, if you’re working on a project that includes software for embedded systems, driver software, or pretty much anything low that’s close to machine-level code – you’ll probably be better served with a lower language like C++. It’s not as easy to work with or learn because C# usually handles a lot of “overhead” that the programmer would otherwise have to take care of manually in C++.

How long do C# projects normally take?

The length of a project depends on many factors, including the scope of your project and the technical complexity of it. When you post a freelance C# project request on Codementor, you’ll have the option to indicate when you’d expect the project to be completed. We suggest chatting with the interested developers to ensure both sides are on the same page. For more information on how to post a freelance C# request on Codementor, check out our article.

How much does it cost to hire a freelance C# developer?

We don’t charge anything when you post a freelance hiring request for C# developers! You’ll have the chance to determine what the budget for your project is when you post the request. You’ll only need to pay the developer if you’re 100% satisfied with their work. Please know that Codementor charges a small service fee when a developer completes the job.

What skills should I look for in a C# programmer candidate?

Most C# developers work on programs and apps for the Windows OS, usually within the .NET framework. Their tasks include designing and creating user interfaces, writing and debugging code, and maintaining programs. A successful freelance C# programmer must possess in-depth knowledge of the .NET framework and C# itself, along with high-level coding and problem-solving abilities. Ideally, a freelance C# candidate will be capable of full-stack development. In practice, this usually means a bachelor’s degree in information technology, computer science, computer programming, or other related fields, with a Microsoft Visual Studio certificate and relevant experience with .NET 3.5 (minimum) and C#. If you’re looking for a senior or mid-level candidate, at least 2 years of work experience as a freelance C# developer is required. Also, knowledge of C++, C, Java, or any other programming languages is a plus. In terms of “soft skills,” someone with excellent verbal and written communication capabilities is a good candidate – and being able to complete tasks with little to no supervision is excellent too.

What makes Codementor C# developers different?

We do a comprehensive technical and communications screen of all C# developers at Codementor. Our network includes book authors, popular open source contributors, top Stack Overflow users and engineers at top tech companies. In addition, to continually ensure the quality of our freelancers, we regularly check in on existing C# developers’ user satisfaction rates.

What C# interview questions should I ask freelance applicants?

Here are a couple of common C# interview questions to ask your prospective contract C# developer: What are the four basic classes in C#? Describe C# garbage collection. Explain Common Language Runtime (CLR) architecture. Compare C# and C++. Compare C# and C. Explain multiple inheritances and whether it works in C#.

What happens if I’m not happy with the freelancer’s work?

As a platform, we strive to ensure you’re always happy with your C# project’s results. If you’re unsatisfied with the results, you can choose to get a refund for the project. Additionally, you can contact our support team should you need any further assistance with your project.

5+ Yrs Unity 3D Game Development, C#, .NET Core, API / Web / Desktop / Mobile Developer, MVVM/MVC, SQL, Entity Framework, Code First

Being a software developer is more than just learning to program in a computer language. I have been building multiplayer games since 2015, primarily in Unity 3D using Photon Bolt or Photon Fusion (server-authoritative). In the past I have also designed several larger web sites from concept to deployment, some high-profile projects. I have served as a Lead Developer or Senior Developer for years, mentoring other developers and encouraging them to use the latest technologies and best practices. For tutoring, I would focus on teaching patterns, using events, and reusable methods for designing applications and reinforcing the need to stay current as new technologies are released. I can give advice on how to focus your learning efforts to target specific types of development positions, and interviewing advice for finding a position within a software company. I had been a developer in C++ for about 10 years prior to using C# and focused on web technologies, which I have now been doing for another 10 years. While I have primarily been using Unity 3d, Microsoft .NET / C#, I have also utilized VB and VB.NET, touched on Linux/PHP/MySQL from time to time, and worked with the Microsoft SQL Server/Express/CE products for 10+ years. I originally started building a Unity 3D game about 5 years ago, which passed Steam Greenlight and I am currently working on multiple Unity mobile and desktop games. Domain Driven Design is a basis for each of my projects' structure, and I reinforce the need to use best practices when coding. I can also explain SCRUM, which is used by many companies for handling team project management. For Unity 3D multiplayer networking projects I typically work with and recommend Photon Fusion along with PlayFab, PlayFab Matchmaking, and PlayFab Servers. I recommend and use PlayFab in most all of my projects. If your final senior project is a "Concept to POC" type of project where the Proof of Concept is the working software required for a grade ,then I will also teach you to use Azure DevOps with a Git repository to manage the project (or Plastic for Unity projects), and Invision to wireframe your ideas before we begin developing any code. I can help you document the Project Scope, Functional Specs, create Design Documents, and build the presentation for your senior college project. We can build completed projects in a short time, both the user interface and the server components as needed. My focuses are Unity 3D, C#, .NET Core, HTML5 / CSS3, jQuery, Object Relational Mapping (Entity Framework or nHibernate), Microsoft .NET, Web Services, Azure, Photon, PlayFab, SQL Server, SQLite, Cosmos DB.
