After installing Windows, my next job is to install Net Framework and then other software.

When you download a certain software or tool from the internet and ask to install more Net Framework (NF). So why install NF and what is NF? Let’s find out together:

.NET Framework is a programming platform and also an application execution platform mainly on Microsoft Windows operating system developed by Microsoft. Programs written on the .NET Framework will be deployed in a software environment (as opposed to .) hardware environment) is known as the Common Language Runtime (CLR). This software environment is a virtual machine which provides services such as software security (security), memory management (memory management), and exception handling (exception handling).

.NET framework includes a large set of programming libraries, and these support the construction of software programs such as programming interfaces; access, connect to the database; web application; algorithms, data structures; network communication… The CLR along with this set of libraries are the two main components of the .NET framework.

.NET framework simplifies application writing by providing many pre-designed components, programmers just need to learn how to use and be creative to tie those components together. Many tools are created to support building .NET applications, and IDEs (Integrated Development Environment) is developed and supported by Microsoft itself as Visual Studio.

This is the latest version of Net Framework 4.5.2 from Microsoft, compatible with the following operating systems:

• Windows Vista SP2
• Windows 7 SP1
• Windows 8
• Windows 8.1
• Windows Server 2008 SP2
• Windows Server 2008 R2 SP1
• Windows Server 2012
• Windows Server 2012 R2

Today we will try to learn about how to hijack Server Bootrom, cash registers, Routers to redirect DNS, install spyware by TPress the Bootrom system of the net shop

Tools needed:

• 1 DDNS or No-ip account (Articles about DDNS, No-ip You can find a lot of tutorials on the website DDNS, NO-IP ).
• Nmap (Download Nmap)
• 1 thinking investment

Let’s start practicing:

Step 1:

First, you need to determine the IP range allocated to the workstation and its Gateway. To determine the IP range for workstations and Router’s Gateway, go to cmd and type the command ipconfig then Enter

IPv4 Address is the IP of my machine: 192.168.1.108

Default Gateway of the system is: 192.168.1.1

Usually, the focus will divide the system into 2 IP ranges

• 1 series for Bootrom machines (192.168.1.2 -> 192.168.1.99)
• 1 array of workstations. (192.168.1.100 -> 254)

Step 2:

Install Nmap software. Just click Next and you’re done.

After the installation is complete, open Nmap and scan the IP ranges and ports of the net shop

• In the Target section: is the network range to be scanned: 192.168.1.0/24.
• Under Profile: select Intense Scan, all TCP Port.
• Then click Scan

Wait for the results to appear (a bit long)

In the result we have 10 hosts that are online:

• 1 host can be Linux,
• 8 hosts are Windows
• What is an unknown host?

Shown above Getway of Router is 192.168.1.1, in the picture after scanning we see that it is a Linux host. Maybe this host is the Router because usually Router devices will run on Linux source code

In the results of Nmap, we see that the Router is opening 2 ports, 53 and 80 (web port).

We try to enter a web browser and type the router’s IP: 192.168.1.1

The user and password are often changed by the net shop owner because it will be troublesome if they do not have IT knowledge, and when the technical staff comes to handle the problem, it will be more complicated. So they usually leave the default user/password

Now we try user: admin, pass: admin.

Wow, so you can access the router’s configuration page. They use TotoLink equipment

We are already half way here. Should not continue at the net shop, now find a way to go home and still access this Router. So we use the DDNS function to assign the domain name to the static ip of the net shop through the Router

This is how I can remotely remote into the Router. Go to menu: Management -> DDNS.

Select No-IP, then type the domain name registered on No-ip. Login information then save and reboot Router

Finished 1 child: 192.168.1.1

The next time we see what is the IP 192.168.1.2 of the net shop? (it runs Windows operating system, open port 3389 (port remote desktop) So we can remote computer 192.168.1.2 according to speculation this will be Bootroom server

Try Remote Desktop.

• Into the run type command mstsc.
• Enter Computer: 192.168.1.2

A dialog box asking for a Remote account appears

Now we have to use the guessing method, usually simple passwords such as the owner’s name, password, 123456, 123@abc … Good luck

If successful, the image below will appear

Remote can enter Bootrom, what to do next is up to you!

UDP Flood Attack Tool

This tool attacks the victim’s IP according to the port of choice, I tested it for 1 customer and the network went down at the net shop the customer was sitting in, and it was reported that I had to wait for nearly 10 minutes to contact the customer.

It can be said that this is a somewhat powerful tool, you should use it for learning purposes, not to destroy it.

Finally, the first Windows 11 error has appeared. This is one of The reasons I don’t like Windows 11 there. Fortunately, this error is not too serious and I can guide you to fix it. Who is wrong? 0x800F0950 When installing .Net Framework from 2.0 to 3.5, read on.

Fix Windows 11 error that cannot install .Net Framework 3.5

Since the current Windows applications are all written on the .Net Framework, installing the .Net Framework 3.5 is very important to play games or use software on Windows. On Windows 11 you can’t install .Net Framework by going to Control Panel -> Programs -> Programs and Features and turning on -> Turn on Windows Feature on or off, so when installing you will get an error 0x800F0950 . Instead we have to set it manually through the command line.

This article will guide you to fix the error 0x800F0950 when installing the .Net Framework 3.5 of Windows 11.

First, right-click the Windows 11 ISO file and select Mount. Those of you who still have the Windows 11 installation file do not need to download it. And those of you who do not have the Windows 11 installation file? Download here.

Please notice the Mount drive symbol. My Mount drive is drive E.

Next, you open cmd with admin rights by pressing Start Menu, enter cmd and select “Run as administrator”.

Then enter the following command: Dism /online /enable-feature /featurename:NetFX3 /Source:(drive letter):\sources\sxs /LimitAccess

Replace (drive letter) to your Mount drive letter. Drive example Mount Mine is drive E:.

So you have successfully fixed the first Windows 11 error. I wish you a successful installation of .Net Framework. Also, if you want to know more new features of Windows 11 then read this paragraph Please.

Do you want to check the version .NET Framework on Windows 10 using the PowerShell command or using File Explorer to check the .NET version. And here’s how.

Use Powershell to see the .NET Framework version

A quick and easy way to check your .NET Framework version is to use PowerShell. Run the command below to list all the framework versions installed on your PC.

First, open PowerShell by opening the Start Menu, searching for “Windows PowerShell” and clicking on the first result.

On the PowerShell window, type the following command and press Enter:

Get-ChildItem 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP' -Recurse | Get-ItemProperty -Name version -EA 0 | Where { $_.PSChildName -Match '^(?!S)\p{L}'} | Select PSChildName, version

PowerShell will display a list of .NET Framework versions installed on your system. Here, the highest number is the latest framework version available on your PC.

So you have seen the .NET framework version using Powershell already.

Check .NET Framework version in File Explorer

You can also view the version of the .NET framework that you have installed from File Explorer. You need to go to the folder C:\Windows\Microsoft.NET\Framework on your PC.

To quickly open the “Framework” folder in File Explorer, open Run by pressing Windows + R.

In the Run box, type the following path and press Enter. If you installed Windows 10 in a drive other than the C drive, replace “C” with the letter of the Windows installation drive in the path below.

C:\Windows\Microsoft.NET\Framework

In the Framework folder window, find the folder that shows the highest version and open it.

In the screenshot below, “v4.0.30319” is the highest numbered folder and I will open this folder.

Note: The other folders here represent different versions of .NET Framework installed on your PC. Remember that your PC may have multiple versions of the .NET Framework installed.

Find the file “Accessibility.dll”.

Right click on “Accessibility.dll” and select “Properties”.

On the “Properties” window, click the “Details” tab at the top.

The “Details” tab will display various information about the file you selected. Here, look for the value next to “Product version” because it is the latest Framework version installed on your PC.

In the image below, that value is 4.8,4084.0.

So you have checked the Framework version with File Explorer already. You must feel lucky for the first mistake above Windows 11 It is not possible to install the .NET Framework.

Python is an open source, interpreted, and general-purpose programming language. It follows Java and C functionally. Python is easy to learn, and as a language with high-level programming capabilities, some sites that use Python are Reddit, Pinterest, YouTube, and Instagram. As one of the most popular programming languages, Python is heavily used in modern development trends such as machine learning. Also, if you are new to programming, Python is where you should start your programming journey.

Every passing day brings new advancements in technology, and now times have changed that only the oldest companies can thrive. Along with that, the capacity and quality of specialized languages ​​is also growing at a rapid pace. That’s one of the main reasons why it’s so difficult to choose the most appropriate programming language for your next project. It is difficult to pick one out of all the technologies and that is why this article will discuss the two most popular programming languages, .Net and Python.

Python and .Net are both popular programming languages ​​in 2021. Both are based on OOP (object-oriented programming) concept, easy to learn and code, and offer fast and efficient development. great capacity. Each of these languages ​​has its own advantages. Now, let’s discuss which language is best for your next project and why? Python vs .Net. But before diving into the differences, let’s give a quick introduction to both languages.

Overview of .Net

C# or C-Sharp is a powerful and high-level programming language that strictly adheres to traditional C++ and C constructs; however, it has improved and is easier to learn. It is used to develop a large number of complex and large-scale applications. C# code can be compiled on different platforms; This object-oriented programming language has structural similarities, much more in common with Java. You’ll find C# in cutting-edge technologies like Microsoft HoloLens and sites like Stack Overflow.

Advantages of C#:

C# is a multi-paradigm programming language; Here, classes are grouped into one or more namespaces allowing you to create a set of reusable libraries.

1) Cross-platform app:

Microsoft has released a new version of the C# .NET framework, which is compatible with Linux, Windows and MAC operating systems. .NET Core provides forward-looking development, an enhanced version of .NET, improved adaptability and scalability. Improvements are updated in each subsequent version of this language.

2) Overload

C# offers flexibility in overriding functions, which means having the same name but different parameters to meet other application requirements.

3) Garbage collection

Garbage Collector automatically maintains memory in .NET applications. It continuously removes and cleans all the garbage. Every time an object is called by a function, the CLR (Common Language Runtime) allocates memory with an updated graph.

4) Language .Net

C# is also known as .Net language. That’s because it promotes interoperability, i.e. it can access any code written in the .Net framework. In addition, you can also access COM components, which is easier to do than in any other language.

5) Abstraction

The general purpose of abstraction is not to be tied to a concrete member. In C#, this idea means that a class or method need not be associated with a particular instance.

6) Security

ASP.NET Core allows developers to quickly configure and manage the security of their applications. It includes features for maintaining authentication, authorization, HTTPS enforcement, data protection, application confidentiality, CSRF/XSRF prevention, and CORS management. These security features allow you to develop powerful yet secure ASP.NET Core applications. ASP.NET also provides the following authentication and authorization: Windows authentication, forms-based authentication, passport authentication, etc.

7) LINQ

The Microsoft partnership has provided LINQ as a powerful component with C#. LINQ is a .NET element that allows native query processing directly in C#.

Main features:

• Simple, powerful and extensible.
• High-level structured programming language.
• Integration with the .NET framework. Modern syntax, easy to learn.
• Extensive standard library.
• Code safe, C# doesn’t allow untrusted casts.
• Fast compilation and execution times.

Applications of C#:

• Games using Unity
• Class Library
• Web Application, Client-Server Application
• Windows applications that run on the desktop
• Console Application
• Web service application

Python Overview

Python is an open source, interpreted, and general-purpose programming language. It follows Java and C functionally. It’s easy to learn, and it’s a high-level programming language — sites that use python are Python Reddit, Pinterest, YouTube, and Instagram. As the most popular programming language, Python is widely used in modern development trends such as machine learning. Also, if you are new to programming, Python is the language you should start your programming journey with.

Advantages of Python:

1) Data structure: Python handles the conversion of data types at runtime when the application starts. Thus, it provides the dynamic execution of a program, making it easy for programmers to understand.

2) Readability: Python has the potential for exceptional readability, resulting in properly written code. Python includes PEP 8 documentation available for programming language formatting.

3) Integration of third parties: With the help of the Python Package Index (PyPI), Python can integrate a large number of third-party modules.

4) Open source code: Python has an active support community that contributes significantly to stabilizing and deeply exploring a language. Furthermore, it is free to use under the GPL (a free software license).

5) Mobile: In the case of system-dependent functionality, this program can run on different platforms without modifying the code.

6) Supports major libraries: Python has a vast library and you can experience most of the necessary functions there, such as string processing, web service stuff, internet, etc.

Main features:

• Python is developed under an open source license.
• Supports both structured and functional programming and object-oriented programming.
• Easy to code, maintain, and read.
• A solid, compatible and portable standard library on different platforms like Windows, Unix or Mac.
• It also supports garbage collection.

Python applications:

• Prototyping
• Software development and language development
• GUI-based desktop applications
• Graphic design and games
• Image processing applications
• Commercial and Enterprise Applications

Comparison between C# and Python

Now that we have a basic understanding of these two languages, let’s compare them in more depth to understand some of the key differences:

1) Easy to use

C#

C# developers often need to have a basic knowledge of the structure of the language in the form of functions and classes. So, C# is a perfect choice for those with Java experience.

Python

Python does not need to know the different constructs of the language. Because Python developers can learn and understand more in the process of coding.

2) Speed ​​of programming and development

C#

C# provides a set of predefined libraries that can be used in a particular syntax. You can also use some tips and tricks to speed up programming in C#.

Python

Python is an extremely readable programming language that places more emphasis on coding than learning the syntax. It has simple syntax and doesn’t require extra semicolons in each line of code to separate line statements.

3) Dynamic and Static

C#

C# is a static programming language. Therefore, it should compile the written code before running any program and identify compilation errors. For example, data types must be defined before execution. Otherwise, the program will throw an exception and fail to compile.

Python

Python is a dynamic programming language. It does not require any variable declaration, which means that the data type of the calling variables will be determined at runtime. In Python, the process is simpler and faster – it runs instantly.

4) Performance

C#

C# is a programming language compiled to extend the compile time of a program. As a result, writing code takes more time and effort, but produces more efficiency in execution.

Python

Python is an interpreted language; so its speed depends on the coder. However, it also runs very fast when the program starts.

5) Applications

C#

C# is an object-oriented programming language used to develop applications ranging from desktop to game development. However, when it comes to implementing machine learning applications, C# is still limited in terms of libraries.

Python

Python is an open-source, multi-paradigm language, and an extremely popular choice for machine learning. It is used to develop highly scalable applications with well-known libraries like NumPy, Pandas, TensorFlow, etc.

6) License

C#

C# has an official IDE i.e. paid Microsoft Visual Studio software for large businesses and organizations. It also has a free version for small communities and individual developers but with limited functionality.

Python

Python is a general-purpose programming language licensed under the GPL. It is open to anyone and can be added to the Python community. It is significantly cheaper than C#, which requires licensing costs to build .NET applications.

Conclusion

Now that we’re done with this article, we need a bit more clarification on the same question: Python versus .Net (#C)? It is not easy to choose which is best. Furthermore, it is difficult to compare because these tools are extremely different and serve different purposes. These two high-level programming languages ​​are easy to learn and code. They provide high performance and allow implementation of object-oriented concepts. C# is widely used in business applications, while Python is more flexible and easier to learn.

Python seems more great for data analysis, machine learning, while .NET is ideal for developing scalable and powerful business applications. In terms of community support and some interesting open source projects, Python is better. However, Microsoft offers more interesting features in terms of productivity and optimization, especially with .Net Core, which is very popular.

Python can be the optimal choice if your project depends on high speed and performance. It is easy to learn, provides options for smooth cross-platform development, and provides developers with a useful open source library that speeds up the development process. However, if your project needs top performance, Microsoft integration and depends on standard libraries and syntax, then C# is the better choice.
