“Bad binary signature” in ASP.NET MVC application

Question

We are getting the error above on some pages of an ASP.NET MVC application when it is deployed to a 64 bit Windows 2008 server box. It works fine on our development machines

Answer 1

BadgerB in this thread might be on to something:

Am I mistaken or is this error supposed to be caused when a dll is changed in a significant way (the signature of a method call is changed) without recompiling the code that uses the dll to take the new signature into account.

It sounds like the difference between the working and not-working scenarios is the machine/environment used to build the binaries. Could it be that when building with TeamCity on a 64-bit machine, the interface or signature of some method is changing which is then causing this error?

Can you post the full call stack of when this exception occurs? Are there any COM objects or P/Invoke calls to native code? Are you using any native code?
