Managed code is code that is executed by the Common Language Runtime (CLR). The CLR provides services such as memory management, security, and exception handling for managed code.
What is Unmanaged Code?
Unmanaged code is code that is not executed by the Common Language Runtime (CLR). It is typically written in C or C++ and is compiled directly into machine code.
What is Microsoft Intermediate Language (MSIL)?
Microsoft Intermediate Language (MSIL) is a low-level, platform-independent language that is used by the Common Language Runtime (CLR). .NET code is compiled into MSIL, which is then executed by the runtime environment.

ASP.NET is a framework for building web applications using .NET, while ASP.NET Core is a cross-platform, open-source framework for building web applications using .NET. ASP.NET Core includes many of the same features as ASP.NET, but it is designed to be more lightweight and modular.
What is the .NET Core Runtime?
The .NET Core Runtime is the runtime environment that manages the execution of .NET Core applications. It includes a just-in-time (JIT) compiler, which compiles .NET Core code into machine code at runtime.
What is the .NET Core SDK?
The .NET Core SDK is a set of tools for building and deploying .NET Core applications. It includes a compiler, a runtime environment, and a set of libraries for building applications.
What is the difference between the .NET Framework and .NET Core?
The .NET Framework is a software framework developed by Microsoft that provides a runtime environment for executing applications on Windows. .NET Core is a cross-platform, open-source framework for building modern applications that can run on
