- 4. Microsoft Intermediate Language- Meta Data MSIL is a (IL) Intermediate Language, also Known as (CIL) Common Intermediate Language, or popularly the (MSIL) Microsoft Intermediate Language, is the Core of the .NET Framework. Microsoft Intermediate Language converts the source code into intermediate language and then machine code by JIT Compiler 4
- 5. Microsoft Intermediate Language- Meta Data All .NET source codes written in any .net supportive language (C#, VB.net etc), when compiler are converted to MSIL. This MSIL at the Runtime, gets converted to machine code. The Runtime convention of MSIL code to the machine code is handled by a component called as the Just In Time (JIT) Compiler. 5

- 7. Microsoft Intermediate Language- Meta Data In other words, when we compile the code that uses the .NET framework library we don’t immediately create operating system specific code, we compile our code into IL. This IL is not specific to any O/S and also is not specific to any language supported by the .NET languages e.g. VB.NET, C#, J#, VC++ etc. IL is also a language, which is converted into machine code JIT (just in time) compiler. IL is independent of the O/S machine. 7
- 8. META DATA 8 Data about data is known as metadata, example, name, size, version of a file is metadata about that file Information produced by an application to describe the properties. The metadata holds the interface definition of the classes, fields, methods and other program elements. The CLR uses metadata to load and run applications.
- 9. Microsoft Intermediate Language- Meta Data .NET metadata, in the Microsoft .NET framework, refers to certain data structures embedded within the Common Intermediate Language code that describes the high-level structure of the code. Metadata describes all classes and class members that are defined in the assembly, and the classes and class members that the current assembly will call from another assembly. The Mr. Sanjay Tejasvee(9251933560) MIT 402: .Net Framework and Programming in ASP.Net 9
- 10. Microsoft Intermediate Language- Meta Data metadata for a method contains the complete description of the method, including the class (and the assembly that contains the class), the return type and all of the method parameters. A .NET language compiler will generate the metadata and store this in the assembly containing the CIL. When the CLR executes CIL it will check to make sure that the metadata of the called method is the same as the metadata that is stored in the calling method. This ensures that a method can only be called with exactly the right number of parameters and exactly the right parameter types. 10
