- The main function of Common Language Runtime (CLR) is to convert the Managed Code into Native code and then execute the Program.
- The Common Language Runtime (CLR) uses Just In Time (JIT) compiler to converts Intermediate Language (MSIL) to Native code/ Machine code.
Functionality of CLR
- Memory management
- Thread management
- Security management
- Garbage Collection (GC)
- Runs the code on different platform
BCL – Base Class Library
BCL provide the fundamental building blocks for any application you develop, Web application or Windows application.
The .NET framework provides a set of base class libraries which provide functions and features which can be used with any programming language which implements .NET, such as Visual Basic, C# (or course), Visual C++, etc.
Base Class Library Namespace
- System.Data – Is the namespace for ADO.NET
- System.IO – Provides connection to file system and the reading and writing data.
