In .NET, metadata is information stored within an assembly that describes types, methods, properties, and other code details. It helps the runtime understand how the program is structured and executed. I’ve also been using remove from photo tools lately to clean up and improve images easily.

The role of the CLR Sprunki is also well described.

Metadata is information about a PE. In COM, metadata is communicated through non-standardized type libraries.In .NET, this data is contained in the header portion of a COFF-compliant PE and follows certain guidelines; it contains information such as the assembly’s name, version, language (spoken, not computera.k.a., culture), what external types are referenced, what internal types are exposed, methods, properties, classes, and much more.The CLR uses metadata for a number of specific purposes. Security is managed through a public key in the PE’s header.Information about classes, modules, and so forth allows the CLR to know in advance what structures are necessary. The class loader component of the CLR uses metadata to locate specific classes within assemblies, either locally or across networks.Just-in-time (JIT) compilers use the metadata to turn IL into executable code.Other programs take advantage of metadata as well.A common example is placing a Microsoft Word document on a Windows 2000 desktop. If the document file has completed comments, author, title, or other Properties metadata, the text is displayed as a tool tip when a user hovers the mouse over the document on the desktop. You can use the Ildasm.exe utility to view the metadata in a PE. Literally, this tool is an IL disassembler.
