How to rigister .Net 4.0 assemblies to the masterpage in sharepoint

Hi Everyone,

Am unable to register the assembly which was generated through the Visual Studio 2012.Because Those .dll files will be under the path "C:\Windows\Microsoft.NET\assembly\GAC_MSIL\test.dll". There is no public key token and version information in this folder.

How to find out the Version and public Key Token information for the .Net 4.0 assemblies.

Regards,
