I am developing an application which references and uses some third party assemblies from a certain Vendor; in development box I have these 3 assemblies in a reference folde
Use SN.exe : SN -T VendorAssembly.dll, this will return a hex number that is the public key token, then, reference the assembly from app.config. To get the version right click your vendor assembly and use that for the codeBase version value, the href=path you mentioned.
