Every assembly, whether static or dynamic, contains a
collection of data that describes how the elements in the
assembly relate to each other. The assembly manifest
contains this assembly metadata. An assembly manifest
contains all the metadata needed to specify the assembly?s
version requirements and security identity, and all metadata
needed to define the scope of the assembly and resolve
references to resources and classes. The assembly manifest
can be stored in either a PE file (an .exe or .dll)
withMicrosoft intermediate language (MSIL) code or in a
standalone PE file that contains only assembly manifest
information. It contains Assembly name, Version number,
Culture, Strong name information, List of all files in the
