How to tell开发者_如何学运维 if .net app was compiled in DEBUG or RELEASE mode?

Hi,

If I have third party pre-compiled code, how can I tell if the .dll's provided are release or debug versions?

If the .pdb files exist alongside the .dll's, does that mean the dll's are debug versions?

Thanks Nic

Not necessarily - there can be .pdbs transferred as well - you could look at the dll using reflector and check that the assembly information - if there is a Assembly: debuggable information like below

then its debug
