debug nhibernate original release

I downloaded the binaries of nhibernate from their original site, if i get the source code, can i debug their binaries??

what I mean : I don't wa开发者_如何学Cnt to rebuild the source code and take the binaries to the project and then debug them.

BTW they don't provide a pdb files with their binaries.

i just want to link my source code to the already exist binaries?

when i try to open the modules window and choose to load a symbol file : Nhibernate.Pdb i get this message :

A matching symbol file was not found in this folder.

Try getting the symbols from http://www.symbolsource.org/

PDBs are provided starting with NHibernate 3.0.
