Want to hire freelance C# developers on your own? Here are the skills you must look for while hiring a C# freelancer

Hiring freelance C# developers might be an intricate task for you if you are a non-technical manager. C# is one of the most demanding skills of 21st century. C# is used for various purposes like cloud applications, console applications, game development, dynamic website development, and much more.  But, hiring the most skilled freelance C# developers among  thousands of developers is challenging for anybody. So, here UltraGenius comes to assist you while recruiting the top freelance C# developers on your own. UltraGenius understands your job requirements and gets you only the top freelance C# developers who have professional experience in C# development.

The following skills you must look for while hiring a freelance C# developer – 

Proficient using C# and well-versed with its ecosystem

C# is a high-level object-oriented programming language similar to C++, Python, and Java. C# freelance developer must be aware of databases, language syntax, regular expressions, framework classes, HTTP protocol, etc. The developers must know about handling events, performing asynchronous operations, programming an UI, and have a skill of writing reusable C# libraries.

Firm understanding of Object-Oriented Programming concepts

C# is widely used as an Object Oriented Programming language. OOP helps to implement real world entities. For example, if you want to design a messaging app, you have to first design a message class that contain all the information about sender,  message content, receiver, and message identity all inside a single class. The freelance C# developer must know about Encapsulation, Inheritance, Polymorphism, and Abstraction. Check whether the freelance C# developer knows about early or static binding (Compile-time Polymorphism), dynamic binding or late binding (Run-time Polymorphism), various types of inheritance, etc.

Familiarity with C# concurrency patterns

C# provides a thread pool for enabling parallel processing of tasks. It allows multiple threads to run concurrently and enables multi-threading by utilizing more than once processors. Due to the concurrency patterns, the throughput of the work is increased as it saves the idle time of CPU.

Knowledge of C# software architecture and design patterns

C# is a high-level modern programming language promoting object-oriented way of software development. C# offers semantic and syntactic constructs which are directly aligned with Object Oriented Design. C# embeds the patterns like Singleton, Decorator, Strategy, Composite, and more. The software architecture of C# is based on the SOLID principles. IT helps developers to avoid creating a class with multiple responsibilites.

Experienced in working with Version Control System (VCS)

Freelance C# developers must know how to use add, push, pull and commit commands in Git. It is the version control system that helps teams work by collaborating their code and maintaining change frequency of the code (mostly with frequent changes). The developer also needs expertise on branching as it allows them to work independently on a specific project’s history.

Knowledge of C# frameworks and libraries

Familiarity with C# frameworks helps freelance C# developers greatly. Microsoft .NET, ASP.NET, ASP.NET Core, Mono, ADO.NET, Blazor are some of the popular C# frameworks. C# also provides a vast collection of libraries like AForge.NET, Accord.NET, Meta.Numerics, Math.NET Numerics, ALGLIB and also an Open Toolkit (Open TK) which provides a low-level binding for OpenAL, OpenGL, and OpenGL ES, etc. 

Experience working with .NET framework

.NET is widely used C# framework for developing various types of applications. It provides the developers an advantage of language interoperability. .NET framework eases the software development with its Framework Class Library (FCL) , which provides numeric algorithms, web application development, user interface, database connectivity, data access, etc.

Understanding of SOLID principles

Understanding SOLID principles is the core skill required for any Java developer. Java is designed to reduce dependencies among classes so that software engineers can work in modules easily and change one part of software without affecting the other. SOLID stands for – Single Responsibility Principle, Open/Closed Principle, Liskov Substitution Principle, Interface Segregation Principle, and Dependency Inversion Principle. 

Knowledge of Dependency Injection (DI)

A Dependency Injection (DI) Container is a framework used for creating dependencies and automatically inject them into the code. DI is also referred to as Inversion of Control (IoC). DI creates the object based on the request and injects in the code whenever required.  It maintains the lifetime of objects. Castle Windsor, Spring .NET, StructureMap, Autofac, Unity, and Ninject are most useful DI containers.

Proficient in writing optimized and readable code

The freelance C# developer must have a strong problem solving skill as it helps developers to utilize existing solutions for the projects more efficiently, thinking abstractly, and enables them to write pseudocode for their project. The developer must know how to debug the code as well. Also, check if the freelance C# developer is able to write clean and concise code and can fluently communicate with other team members while explaining the code.

Knowledge of Common Language Runtime (CLR)

Common Language Runtime (CLR) is the run-time and service environment for executing the Common Intermediate Language (CIL) code. CLR implements the Virtual Execution System (VES). CLR increases portability by removing the need of re-compilation of the program. It also provides automatic garbage collection facility and enables faster creation of multi-threaded and scalable applications as the C# freelance developer doesn’t have to think much about memory management and security related stuff.

C# is used for various purposes like cloud applications, console applications, game development, dynamic website development, and much more. But, recruiting the best freelance C# developers is not an easy task when a large no. of C# freelancers are competing to grab the job opportunities.  

Top Interview Questions to ask while hiring a freelance C# developer

Common Language Runtime (CLR) is the virtual machine component for executing .NET programs. CLR internally includes a JIT (Just-IN Time) compiler which converts the Microsoft Intermediate Language (MSIL) code into the assembly or machine code which is further executed by the processor. 

CLR has the following benefits - 

  • It enables faster execution of programs as developers don't need to bother about memory and security related issues.
  • CLR uses delegates instead of pointers so comparatively more secure than C or C++.
  • CLR provides cross-language integration.
  • CLR has in-built support for the components that are developed in other languages of .NET framework.

The class is the blueprint of an object and encapsulates data members and member functions into a single unit. C# provides four types of classes - 

  • Static  - A static class doesn't allow any class to inherit it and inhibits itself from being instantiate. It uses the keyword static.
  • Abstract - An abstract class provide only the basic layout of the functionality which its child class needs to implement. It uses the keyword abstract.
  • Partial - Partial class provide its members the advantage to share or divide the (.cs) files. It uses the keyword partial.
  • Sealed - A sealed class doesn't allow inheritance. It uses the keyword sealed.

 

The managed code runs on the managed virtual execution system (VES) of Common Language Runtime. Managed code provides various services including faster program execution, more security, multi-threading, exception handling, garbage collector, etc.

The unmanaged code doesn't provide the high-level language services as it runs outside the .NET and is not a part of the CLR.

Indexers allows the class objects or struct instances to be indexed as an array. If a freelance C# developer defines an indexer for a class, that class will act as a virtual array. An array access operator ([]) is used to access the objects of a class using indexer. The C# freelance developer can also set or retrieve the indexed value without pointing a type member or an instance. 

Indexers differ from Properties as the accessor of an indexer takes arguments or parameters.

The equality (==) operator compares the reference of the object while applying while the equals() method compares the value of the object. 

The equality operator returns true if both the references are same and false if they are not pointing to the same object. While equals() method returns true of the value of both the objects is same. For example, int x = 10, y - 10; then x.equals(y) returns true in this case.

The core difference between the StringBuilder and String is that objects of StringBuilder class  are mutable while objects of String class are immutable. StringBuilder does changes to an existing object without creating a new object every time. While if the developer wants to make changes to a String class object then every time a new String object has to be created. 

For example,

string str = string.Empty;

for(i=0;i<500;i++){

str+=i.ToString() + " ";

}

Here, 1001 objects are created out of which 1000 are unuseful.

StringBuilder strb = new StringBuilder();

for(i=0;i<500;i++){

strb.Append(i); strb.Append(' ');

}

 

Generics is a class which gives the C# freelance developer the facility to create general class objects and specify their type at the run-time. Generics enable template programming and reduces the load of typecasting, boxing, and unboxing, and provides code reusability as the code is written for the general types. For example, 

GenericList<Features> list1 = new GenericList<Features>();

GenericList<Struct>list2 = new GenericList<Struct>();

GenericList<Float>list3 = new GenericList<Float>();
