How to Hire a C# Developer

There are plenty of reasons why you might want to hire a C# developer. It is a very flexible and powerful language that can be used to program many different types of applications. C# is also the best language to write Microsoft .NET applications, as Microsoft developed it.

This language was designed to be more straightforward than other, similar programming languages by abstracting the majority of the intricate details so your C# developer can focus on the code rather than the details behind it. However, this isn’t to say you can hire any C# developer. The language has its complexities and needs to be understood by an expert.

Once you hire a C# developer who has plenty of experience and knowledge, there aren’t many limits to what you can achieve as it is a very flexible language. It’s also statically-typed, meaning that errors will usually be discovered before they are built into the application. Because of the way this language is organized, errors are more simple to find, and the codebase is typically very maintainable and scalable.

In addition to helping stop errors, C# being statically typed means that it can often run faster than dynamically typed languages.

Another benefit to C# is that it has a huge community because it is such an accessible language. This means that when you hire a C# developer, they’ll have an easier time finding support for issues and bugs. Additionally, there are plenty of tools that work with C# to make your and your developers’ lives easier.

Additionally, this language is probably here to stay. Because it was developed by Microsoft to build apps on their platform, they will likely continue to update it and make sure this useful language stays relevant. C# is also used on the game development platform, Unity. Because Unity is very popular, too, this language probably isn’t going anywhere.

Why hire a C# developer?

Built from the ground up by Microsoft

This language, as the name implies, is related to C and C++. Microsoft took a look at these to help establish the base of C#, then added new features that they believed would make the language better and more accessible to program with.

They focused on making C# simple, modern, and object-oriented. Because of this, it’s a dominant, flexible language that doesn’t require much verbosity.

Large community

It’s hard to overstate how important a community is for developers. Even if you hire a C# developer who truly knows the language, they can get stuck sometimes. With this language, though, they can post in multiple very active forums or places like StackOverflow to find solutions to any problems or issues that they are stuck on.

Additionally, there are numerous tools related to C# that can help speed up and perfect your development.

Top C# Interview Questions of 2018

Now that you know precisely why you’d want to hire a C# developer, you need to know what interview questions to ask them. If you’re going to skip the hard work of finding great talent, let DistantJob do the job for you and send you a highly vetted, guaranteed expert to join your team.

Explain Boxing and Unboxing.

There are both significant concepts that your C# developer should understand. They are both used for type conversion, but there is a difference between them.

According to the Microsoft programming guide, “boxing is the process of converting a value type to the type object or to any interface type implemented by this value type.” For the CLR to box a value type, it wraps this value inside a System.Object and then stores it on the managed heap.

Unboxing, on the other hand, extracts the value type from the object. Your potential developer should be able to explain that boxing is implicit, whereas unboxing is explicit. As Microsoft explains, “the concept of boxing and unboxing underlies the C# unified view of the type system in which a value of any type can be treated as an object.”

Let’s take a look at an example given in the docs in which the integer variable i is boxed and assigned to object o:

int i = 123;

// The following line boxes i.

Object o = i;

Then, this object o can be unboxed and assigned to integer variable i:

o = 123;

i = (int)o; // unboxing

Explain the difference between the “continue” and “break” statements in C#.

With the break statement, the closest enclosing loop or switch statement in which it appears is terminated. Control is then passed on to the statement that follows the terminated statement, if any.

Instead, the continue statement passes control on to the next iteration of the enclosing while, do, for, or foreach statement in which it appears.

Essentially, “Using break statement, you can ‘jump out of a loop,’ whereas by using continue statement, you can ‘jump over one iteration’ and then resume your loop execution.”

Let’s take a look at an example of each. In this first example given by Microsoft, the conditional statement contains a counter that is supposed to count from 1 to 100, but the break statement terminates the loop after just four counts:

class BreakTest
{
   static void Main()
   {
       for (int i = 1; i <= 100; i++)
       {
           if (i == 5)
           {
               break;
           }
           Console.WriteLine(i);
       }

       // Keep the console open in debug mode.
       Console.WriteLine(“Press any key to exit.”);
       Console.ReadKey();
   }
}
/*
Output:
   1
   2
   3
   4
*/

In an example of the continue statement also located in the Microsoft documents, a counter is initialized to count from 1 to 10. By using this statement with the expression (i < 9), the statements between the continue and the end of the for body are skipped:

class ContinueTest
{
   static void Main()
   {
       for (int i = 1; i <= 10; i++)
       {
           if (i < 9)
           {
               continue;
           }
           Console.WriteLine(i);
       }

       // Keep the console open in debug mode.
       Console.WriteLine(“Press any key to exit.”);
       Console.ReadKey();
   }
}
/*
Output:
9
10
*/
