I'm happy to announce the availability of AssemblyInfo version 2.0. AssemblyInfo is now a Reflector Add-in., adding a new language to Reflector.

In addition to what reflector already shows you, it will show

• General file information, such as size, creation date and last modified date
• All file version information embedded in the exe or dll
• The Authenticode X509 certificate used to signe the file, if any
• All useful information from the COFF and PE headers
• The sections and their characteristics,
• The native dll imports
• All useful information from the CLR header, if any (it works on unmanaged files too)

AssemblyInfo will also show you all information on other .NET metadata, such as types and their members, in a way as close as possible to the internal .NET structures. It's like looking at metadata the way the CLR looks at it, at least that was my intention ;-).

Download AssemblyInfo, unzip it to a location of your choice, and add it to Reflector via the View menu, Add-ins option. Select the AssemblyInfo language from the language dropdown and you're ready to go.

For example, here's the output on the AssemblyInfo.exe module:

// Module AssemblyInfo.exe

I could not have written this without the book Expert .NET 2.0 IL Assembler by Serge Lidin, a book that I can highly recommend if you want to know more about the inner workings of .NET.

Enjoy, and let me know what you think.
