  • Job Description

.NET Core is a lightweight and user-friendly framework. You can incorporate it directly into the application or install it on the server. The framework is quite adaptive and runs faster than other frameworks such as Java Servlet and Node.js. Tasks such as running single queries, running multiple queries, and data updates can be performed quickly. 

You can deploy a .NET core application on Docker containers. It’s highly compatible with popular web-based frameworks, including React and Angular. As per this report, .NET Core is one of the most popular frameworks in the world. 

It’s also a very safe and reliable framework. It has authentication and authorization features that ensure data protection. In addition, this framework can prevent XSRF/CSRF, XSS attacks and uses CORS security management to ensure restricted access to webpage resources. The framework also uses HTTPS and IP safelist to protect itself from malicious users.


Relevance of .NET Core in the present industry.

.NET Core is a very prominent framework. It’s very popular in the IT industry thanks to its wide compatibility and flexibility. In addition, the framework hails from Microsoft, which adds more credibility to it. .NET Core finds vast usage in gaming, machine learning, cloud development, and IoT. Many prominent companies such as Alibaba, Queue-it, LiteTube, and energy2market use this framework.

One of the biggest reasons why .NET Core is so popular is that it’s written in C++ and C#, which are easy to understand and use. And even though these are legendary languages, the framework itself is very modern. .NET Core 3.0 now supports Windows applications such as Windows Forms, WPF and XAML.

It also comes with the latest features such as pattern matching, assembly linking, and enhanced cryptography. It promises active built-in JSON support and IEEE floating-point improvements. 


Issues company face while hiring a perfect .NET Core developer

Often, developers are well-versed with the basic understanding of .NET Core but lack practical expertise to handle projects. For example, they may not know how to implement .NET Core supervision or create industry-level services.

Even though they may be great at application development, many developers don't have enough experience in debugging and bug fixing. Even issues such as application hang and server overload, which can be fixed easily, can create huge problems if left in the error queue. 

Sometimes, even though a candidate has full knowledge of .NET Core, they may face difficulty when using newer versions. These versions may still be in the development phase, which can make it challenging to adapt to new features.


How to select an ideal .NET Core developer?

Before selecting a .NET Core developer, you should ensure their proficiency in C++ and C# development. They should know about ReadytoRun images and should be able to perform Ahead of Time (AOT) compilation through them.   

They should know about .NET core API and standard libraries. The developer should be experienced in application deployment, assembly linking, and cross-platform restrictions. Furthermore, they should be knowledgeable about .NET Core architecture and design principles.  

They should also know about frontend/UI development through Blazor. They should be comfortable with Linux and should be able to work with its serial ports and versions (ARM64 and ARM32).


Conclusion

.NET Core is an amazing app development framework that allows you to create modern applications. This framework is cloud-enabled and allows you to easily scale your projects. You can use it to create cross-platform applications that can be deployed via containers. What’s more - its compatibility and flexibility make it one of the best frameworks for a multitude of web projects. 

Here are some questions you can ask .NET developers before hiring them: 


What is CTS in .NET Core? 

Common Type System is a characteristic feature that determines how the type descriptions and specific values are stored in computer memory. This feature enables programs written in different programming languages to share data. 


What are Metapackages?

A metapackage encloses all the support packages that a .NET core developer requires. It doesn't have any actual code but rather a series of dependencies for different packages.

By adding this package, you bring all the relevant packages and their dependencies into a single project. This feature assists in performing quick application development by eradicating the need to import individual packages.


Describe the function of appsettings.JSON file in .NET Core

It’s an application configuration file that you can use to store and categorize configuration settings. It stores important information such as database connection strings—global variables, information warnings, etc. 


What are the differences between SDK and Runtime in .NET Core?

The runtime has all the tools required to run a .NET core application. It can't compile a program.    

SDK is a collection of libraries and tools that enable developers to build .NET Core applications and libraries. It includes all the essential components required to assemble and run applications (CLI and compiler). The runtime is also a part of the SDK.  


List a few differences between .NET Core and .NET Framework

NET Framework allows application development only on Windows, whereas .NET Core allows cross-platform development on Windows, macOS, OS X, and Linux. If you need to work with Docker containers and microservices or cloud, you should use .NET core.

However, many functions aren’t available in .NET Core, such as NuGet. In those situations, you can use the .NET framework. You can also port your application .NET framework to the .NET core if you require.
