How To Hire a .NET developer in 2018
.NET is a programming framework developed by Microsoft. If you hire a .NET developer, they can build many different types of applications, such as those for the Web, mobile, and more, using numerous different programming languages. If you’re in a hurry to do so, contact us today. If not, read on for the process!
Essentially, .NET is multiple libraries and utilities compiled into one framework so a programming language, mainly C#, can utilize and run on top of it. So, any developers who build their application on top of .NET or use .NET can utilize all of the useful features Microsoft implemented. Also, it’s often easier to interoperate with other applications or languages that are built on .NET.
Hiring a .NET developer can help you reduce development time and create applications more simply and securely. While many coding languages or frameworks go in and out of popularity quickly, .NET has been used in thousands of applications since it was released in 2002, and its association with Microsoft means it’s probably sticking around.
.NET consists of Common Language Runtime (CLR) and Framework Class Library (FCL). The CLR helps to manage memory and assist in the execution of threads and code. It also works to verify code safety. CLR helps make sure that your code is as secure as it can be through its type-and-code-verification infrastructure, the common type system (CTS). It also helps remove the potential of fragmented memory and enhance performance related to memory.
The FCL, on the other hand, is a set of multiple class libraries that execute common functions. These functions could include database interaction, graphics rendering, and more. You could hire a .NET developer to help considerably speed up your development time by letting the FCL accomplish everyday programming tasks, so your developer doesn’t have to.
By hiring a .NET developer, you will save time and money by being able to get the same results with less code. .NET developers come in handy for deployment as well. This framework has features such as controlled code sharing, side-by-side versioning, and more to help make sure that you have fewer conflicts in regards to your deployment and versioning.
This framework is also useful because it helps allow you to develop applications that can be used across different platforms and languages. It’s a language-independent framework, so your .NET developer to hire can be an expert on different compliant languages, such as C#, managed C++, and more, rather than just be restricted to one. Coders can develop applications for desktop, browser, mobile, or applications running on PDA.
.NET also integrates with legacy systems and can process all types of XML documents and write any format of file. Hire a .NET developer if you want a framework that helps you require less code, create projects with more speed, and have increased security.
Top .NET Interview Questions of 2018
What is the difference between a while and for loop? Give a .NET syntax for both types
Every developer you are looking to hire should know the difference between a while and for loop as they are very frequently used any time a unit of code must repeatedly be executed. The for loop is used when the number of iterations is known, whereas the while loop should be utilized until a given statement become true.
An example of this syntax in VB.NET is below.
While condition [is True]
For counter [ As datatype ] = start To end [ Step step]
Next [ counter ]
Explain what .NET web services are
Almost every single application that your .NET developer codes will need to access the web. .NET web services are “reusable components that allow developers to publish an application’s function over the internet to make it accessible and directly interactable with other applications and objects online.”
Web services use the standard web protocols and data formats, such as HTTP and XML, so they can connect across numerous platforms and languages. With ASP.NET your programmers can develop web services, and the .NET framework has built-in classes that are made to build and consume web services.
Explain what a delegate is in .NET
The .NET programmer who you’re interviewing should be able to explain that using a delegate lets the developer encapsulate a reference to a method inside a delegate object, similar to a pointer in C and C++. Then, the delegate object can be given code that can call the reference method without needing to know which method will be invoked at compile time.
Additionally, delegates can be used to create custom events within a class. Here’s an example:
public delegate void FooDelegate();
// custom event
Public event FooDelegate FooEvent;
FooClass FooObj = new FooClass()
FooObj.FooEvent += new FooDelegate();
What is the difference between managed and unmanaged code?
The main goal of this question is to understand if your potential .NET developer to hire understands CLR, which is a major portion of the .NET framework. The CLR provides functionalities that are important for development like memory management and garbage collection and runs managed code, like Visual Basic.NET.
Because of this, the manage code is platform-independent because it runs within the CLR instead of the operating system of the machine using the application. Languages like C or C++ produce unmanaged code, so the CLR doesn’t provide this functionality with them. However, unmanaged code is still used in .NET, such as in COM components, ActiveX interfaces, and Win32 API functions.
Simply Hire a .NET Developer
Now you understand that .NET can help make your developers write code much more quickly and efficiently, saving you time and, ultimately, money. It also assists with security and portability and has strong support because of its relationship to Microsoft.
These interview questions will help you make sure that you hire a .NET developer who can bring experience and skill to the table. However, interviewing about a language you don’t know can be confusing and tedious. Contact us to find a qualified, guaranteed expert without the pain of searching and interviewing to join your team.
