 What is managed and unmanaged code in c#?

In C#, managed and unmanaged refer to two different types of code and resources:

1. Managed code: This refers to code that is executed by the .NET runtime, which provides services such as memory management, security, and exception handling. Managed code is written in languages such as C# and VB.NET and is compiled into Microsoft Intermediate Language (MSIL) code, which is then executed by the .NET runtime. The .NET runtime provides a managed environment that abstracts the underlying hardware and operating system, allowing developers to write code that is platform-independent.

2. Unmanaged code: This refers to code that is executed outside the .NET runtime and does not rely on the services provided by the .NET framework. Unmanaged code is typically written in languages such as C or C++ and is compiled directly into machine code that can be executed by the operating system. Because unmanaged code does not rely on the .NET runtime, it can interact more directly with the underlying hardware and operating system, but it also lacks the services provided by the .NET framework, such as memory management and exception handling.

In addition to code, resources such as memory and file handles can also be managed or unmanaged. In general, resources that are allocated by the .NET runtime are considered managed, while resources that are allocated outside the .NET runtime are considered unmanaged. The distinction between managed and unmanaged resources is important because the .NET runtime provides automatic memory management for managed resources, but unmanaged resources must be explicitly managed by the application to avoid memory leaks and other problems.
