Unmanaged Code Definition:
Unmanaged code is often known as unsafe code. Because it is aimed at the processor architecture, unmanaged code is reliant on the modern computer, in C#.
The CLR handles tasks such as stack management, memory allocation, and release, among other things, so the programmer is free to focus on other things.
Whenever a computer uses the word “unsafe,” the system recognizes he or it will be in control of the program. However, problems like buffer overflows can occur if a coder creates faulty code.
When the .NET framework was released, it was necessary to facilitate calling and integrating unmanaged code into C# programs. This one was applicable to any language that used the .NET framework, not even C#.
There are two main services that provide this assistance. The first one is InteropServices, and the second is Platform Invoke Technologies.
To ingest unmanaged code, you must match one of four factors to be identified;
- (specify the function name and the DLL which holds it).
- Make a class that holds and groups DLLs.
- Prototypes should be written in managed code.
- Make a call to a DLL function.
Advantages Of An Unmanaged Code:
- Unsafe code enhances the validity and reliability of the program.
- The coder is accessible at a low level.
- Unsafe code is used to communicate with the storage.
Disadvantages Of Unmanaged Code:
- There is no safety in the app.
- Errors must be dealt with by the programmer.
- Garbage disposal is not implemented automatically.
- When unsafe code is used, data validation is skipped, which might result in errors.

Managed Code Meaning:
Managed Code means a scheme applied by Microsoft to some high-level programming languages. This is done to have their execution managed by the .Net Framework Common Language Runtime.
Basically, it is a computer programme code that facilitates the system’s smooth operation.
Managed Code helps or facilitates contract of cooperation between the runtime and the natively executing code which states that the runtime may stop an executing CPU to retrieve the information which is specific to that current address the CPU is executing.
Functions of Managed Code:
Managed Code has several functions primary among them being:
It runs in the Common Language Runtime (CLR), which provides services such as automatic memory management, platform-neutrality, and cross-language integration.
Managed Code is applied to ensure type safety, array bound and index checking, garbage collection and exception handling.
Main Features of Managed Code:
1) Managed Code helps us avoid many typical programming mistakes. This is done by using Managed Code through compilation in the managed execution environment.
2) Managed Code supports the programming languages like:
3) Ensures that the code is valid managed code
4) Managed Code changes the entry point in the image to an entry point in the runtime.
5) It is the compiler output of source code written in one of over 20 high-level programming languages.
Conclusion:
There exist differences or distinctions between Managed Code and Unmanaged Code. It is prevalent and only relevant when developing applications that interact with CLR implementations. Many older versions of programming languages have been ported to the CLR. As a result, differentiation is needed to identify managed code, especially in a mixed setup.
