To help, we’ve put together a 10 Essential .NET Developer Interview Questions Checklist with background and sample responses for a recruiter, as well as a few other tips to help make IT recruitment more successful. 

The Most Popular Interview Questions

What is the .Net Framework?

This platform is responsible for creating various applications.It has a list of built-in functionality in the form of classes, libraries, and APIs which are used to build, deploy and run web services and various applications. It supports various languages like C#, VB .Net, Cobol, Perl, etc.

This framework supports the object-oriented programming model.

What is OOP and What does it Mean on the .NET Platform?

OOP stands for Object Oriented Programming. A good answer to this question should point out that OOP languages such as Visual Basic .NET, C#, and C++ are the main languages supported by the .NET Framework (there is also support for functional programming in the form of F#)

OOP allows .NET developers to create classes that contain methods, properties, fields, events, and other logical modules. It also allows developers to create modular programs that they can assemble as applications. OOP has four main features: encapsulation, abstraction, polymorphism, and inheritance.

What is CTS?

CTS stands for Generic System. It has a set of rules that define how a data type should be declared, defined, and used in a program. It describes the data types that should be used in the application.

We can design our own classes and values following the rules contained in CTS. The rules are designed so that a data type declared using a programming language can be called by a program written using another language.

What is a Delegate in .NET?

Delegate objects can then be passed to code that calls the method according to the method’s signature, meaning the developer doesn’t need to know at compile time which method is being called. Delegates are similar to function pointers in C/C++ and have the advantage of being type-safe.

Talking about the perks of working with .NET, it has a high-paying capacity for workers, .NET developer salary guide can be found here:https://devoxsoftware.com/blog/net-developer-salary-guide-based-on-experience-and-location/.

 What is JIT?

JIT stands for Just in Time. A JIT is a compiler that converts an intermediate language into native code.

At runtime, the code is converted to the native language. Proprietary code is nothing more than specifications that can be read by the CPU. You can save your own code so that it is available for future calls.

What is MSIL?

MSIL stands for Microsoft Intermediate Language. MSIL provides instructions for calling methods, initializing and storing values, and operations such as memory handling, exception handling, and more. All .Net code is first compiled into IL.

What Is Meant By Managed And Unmanaged Code?

CLR-managed code is called Managed Code. This code runs inside the CLR. So, to install managed code, you need to install the .Net framework. The CLR manages memory through garbage collection and uses other functions such as CAS and CTS to manage code efficiently.

Unmanaged code is any code that does not depend on the CLR to execute. This means that it is developed in any other language independent of the .Net framework. 

Explain State Management In Asp .Net.

State management means maintaining the state of the object. The object here refers to the web page/control.

The terms “client-side” and “server-side” refer to different forms of state management.

• Client-side – Storage of information on the Page or in the Client’s system. They are reusable, simple items.
• Server side – Storage of information on the Server. It is easier to keep information on the Server than to depend on the client to save the state.

What is Caching?

Caching refers to temporarily storing data in memory so that an application can access the data from the cache instead of searching for its original location. This increases the performance of the program and its speed. The System.Runtime.Caching namespace is used to cache information in .Net.

What is GAC?

GAC stands for Global Assembly Cache. Whenever the CLR is installed on a machine, the GAC is included. The GAC specifically stores those assemblies that will be used by many applications. A developer tool called Gacutil.exe is used to add any file to the GAC.
