NT Service BadImageFormat, but works under forms app

Question

We have a legacy forms application that runs a bunch of 32 bit C++ code along with managed code most of which is built x86 ( but not all.) The forms application works fine. We are porting the functionality/code into a windows service. The service is throwing a bad image format exception when it attempts to execute a particular code path.

We don't have access to all the managed code builds.

Any suggestions on how to attack this problem.

Thanks in advance bille

Answer 1

Solved the problem.

There were two problems with the service side. The actual service executable was built AnyCPU . Also, when building services I always put the main code in a dll to allow console/form app to test drive it. The dll was also built AnyCPU. The form app that is working was built x86.
