I have a project set up where I want to put some code to validate some business objects. This is a NON UI project (No Form) so I have included a reference to my BusinessObjects DLL in this project. All works fine in the code , and BO are referenced  correclty , but when I go to compile the project, I get an error :

---> Error 1 Assembly generation failed -- Referenced assembly 'Kernel_BOLibrary' does not have a strong name KernelCommonMethods

I have the same Business Objects DLL in another project and its workoing fine. Tries rebuilding etc but to no avail

Any ideas ?
