The basic Dot Net Interview Questions and Answers 

These are the most frequently asked Dot Net Interview Questions and Answers that will help you to prepare for your interview.


1)What is .NET?

.NET is a free, open-source, cross-platform framework for building a wide variety of applications using different programming languages. It was developed by Microsoft, and provides a common set of libraries and tools that can be used to create and run applications on different platforms, including Windows, macOS, and Linux. It includes a runtime environment called the Common Language Runtime (CLR), which manages the execution of code, and a large library of pre-written code called the Framework Class Library (FCL), which can be used to perform common tasks such as data access, encryption, and networking.

2) What is .Net framework?

The .NET framework is a software development framework developed by Microsoft. It includes a large library of pre-written code and a runtime environment that allows developers to create Windows and web applications, as well as other types of software, in various programming languages such as C# and Visual Basic. The framework provides a common set of tools and libraries that can be used to create and run applications on different platforms, including Windows, macOS, and Linux. The latest version of the .NET framework is .NET 7.

3) What languages does the .NET Framework support?

.NET supports various programming languages such as C#, F#, and Visual Basic. It also has been evolving to be more cloud native, open, and cross-platform. The latest version of .NET is .NET 7.

4) What are the most important aspects of .NET?

.NET is a software framework developed by Microsoft that allows for the creation of applications for Windows, the web, and mobile devices. Some of the most important aspects of .NET include:
  1. Common Language Runtime (CLR): This is the virtual machine that manages the execution of .NET applications, providing features such as memory management, security, and exception handling.

  2. Class Library: This is a collection of pre-written code that can be used by developers to perform common tasks, such as reading and writing files, connecting to databases, and creating user interfaces.

  3. C# and Visual Basic: These are the two main programming languages supported by .NET, both of which are designed to be easy to learn and use.

  4. Platform independence: With .NET 5 and later, it allows developers to build applications that can run on multiple platforms like Windows, Linux, and macOS.

  5. Interoperability: .NET allows for seamless interaction between different programming languages and libraries, enabling developers to use the best tools for the job.

  6. Security: .NET provides built-in security features such as code access security and role-based security, which help to protect against common security threats.

  7. Scalability: .NET is designed to scale to meet the demands of large, complex applications, and it can be easily integrated with other technologies such as Azure for cloud computing.

 

5) Explain Object Oriented Programming and its relation to the .NET Framework?

Object-oriented programming (OOP) is a programming paradigm that is based on the concept of "objects", which are instances of classes that encapsulate data and behavior.

The key principles of OOP include:

  1. Encapsulation: This refers to the practice of keeping an object's internal state and behavior hidden from the outside world, and only exposing a public interface for interacting with the object.

  2. Inheritance: This refers to the ability for a class to inherit properties and methods from a parent class, allowing for code reuse and abstraction.

  3. Polymorphism: This refers to the ability for different objects to respond to the same method or property in a way that is appropriate for their specific type.

The .NET Framework is built on these principles of OOP, and it provides a rich set of classes and libraries that can be used to create object-oriented applications. C# and Visual Basic are the two main programming languages supported by the .NET Framework, both of which are designed to be easy to learn and use, with OOP concepts and syntax.

Many of the classes in the .NET Framework are designed to be inherited from, and they use polymorphism to allow for a high degree of flexibility and extensibility. The framework also provides a number of built-in features that support OOP, such as garbage collection, which automatically manages the memory used by objects, and reflection, which allows for runtime inspection of objects and their properties.

In summary, OOP is a programming paradigm that is based on the concept of objects and the .NET Framework is a software framework which is built on this paradigm and provides a rich set of classes and libraries that can be used to create object-oriented applications.

SOLVED: Trusted Platform Module Has Malfunctioned - Error Code 80090016

Problem Summary: 
Your computer's Trusted Platform Module has malfunctioned. If this error persists, contact your system administrator with the error code 80090016.
Solutions: 

For Teams: 

Generally Trusted Platform Module (TPM) technology is designed to provide hardware-based, security-related functions. So if any issue occurs with system hardware, security, firewall, and Installed Apps, it should be possible that this type of error message occurs. 
Uninstall the Trusted Platform Module in Device Manager or ON/OFF it and Restart the computer. 
You can also try to create a new Windows profile to check if it helps to resolve this type of issue. 

For Outlook: 

Solution 1: 
Shut down Outlook and set the following registry key. HKCU\SOFTWARE\Microsoft\Office\16.0\Common\Identity\ 
REG_DWORD 
EnableADAL 
0

Solution 2: 
Try Clearing the Trusted Platform Module (TPM) resets the TPM to an unowned state. Note: Clearing the TPM can result in the loss of data. To avoid data loss, make sure you have a backup or recovery method for any data protected or encrypted by the TPM.

How to generate pkcs12 certificate on windows?

Open a command prompt and go to the bin directory under the installation directory.

To create the private certificate type: “openssl genrsa –out private-key.pem 1024” and press [Enter].

For the public certificate type: “openssl req –new –key private-key.pem –x509 –days 365 –out public-cert.pem”
Now it will ask you to enter some information, you can just skip them by pressing [Enter].

Now we need to create the p12 file. Type the following in the prompt: “openssl pkcs12 –export –in public-cert.pem –inkey private-key.pem –out my_pkcs12.p12” followed by [Enter].

Razor Code and Configuration for Umbraco Examine Search

Examine allows you to index and search data easily and wraps the Lucene.Net indexing/searching engine. Lucene is super fast and allows for very fast searching even on very large amounts of data. Examine is provider based so is very extensible and allows you to configure as many indexes as you like and each may be configured individually. Out of the box our UmbracoExamine library that is shipped with Umbraco gives you Umbraco based implementations for indexers and searchers to get started quickly.

Configuration:
 
Step 1: Open the ‘ExamineSettings.config’ file from the ‘config’ folder.
 
Step 2: Create a new Index Provider in the ExamineIndexProviders section:

<add name="MyIndexer" type="UmbracoExamine.UmbracoContentIndexer, UmbracoExamine"/>

Step 3: Create a new Search Provider in the ExamineSearchProviders section:

<add name="MySearcher" type="UmbracoExamine.UmbracoExamineSearcher, UmbracoExamine"/>

Step 4: Open the ‘ExamineIndex.config’ file from the ‘config’ folder.
Create a new Index Set in the ExamineLuceneIndexSets section:

<IndexSet SetName="MyIndexSet" IndexPath="~/App_Data/TEMP/MyIndex" />

Code:
 
@using Examine;
@{
  var searchTerm = Request.QueryString["search"];
}
<ul class="search-results">
  @foreach (var result in ExamineManager.Instance.Search(searchTerm, true))
  {       
    <li>
        <span>@result.Score</span>
        <a href="@umbraco.library.NiceUrl(result.Id)">
            @result.Fields["nodeName"]
        </a>       
    </li>   
  }
</ul>

Solved: Handler “PageHandlerFactory-Integrated” has a bad module “ManagedPipelineHandler” in its module list

It turns out that this is because ASP.Net was not completely installed with IIS even though I checked that box in the "Add Feature" dialog. To fix this, I simply ran the following command at the command prompt

%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i

If I had been on a 32 bit system, it would have looked like the following:

%windir%\Microsoft.NET\Framework\v4.0.21006\aspnet_regiis.exe -i
