How to: Determine an Assembly's Fully Qualified Name
There are several ways to discover the fully qualified name of an assembly in the global assembly cache:
View the global assembly cache directory.
To view the fully qualified names of assemblies in the global assembly cache using the .NET Framework Configuration tool
Click the Start button, point to Administrative Tools, and then click Microsoft .NET Framework Configuration.
Click Manage the Assembly Cache, and then click View List of Assemblies in the Assembly Cache.
For information about using the Global Assembly Cache tool to view the fully qualified names of assemblies, see How to: View the Contents of the Global Assembly Cache.
For assemblies that are not in the global assembly cache, you can use code to output the information to the console or to a variable, or you can use the MSIL Disassembler (Ildasm.exe) to examine the assembly's metadata, which contains the fully qualified name.
For more information about setting assembly attributes such as version, culture, and assembly name, see Setting Assembly Attributes. For more information about giving an assembly a strong name, see Creating and Using Strong-Named Assemblies.
