[Insight-users] ManagedITK: cannot load assembly (System.BadImageFormatException)

[Dan Mueller]

Hi Charles,

MSDN documentation has the following statement:
    In particular, the exception is thrown under the following conditions:
    * A DLL or executable is loaded as a 64-bit assembly, but it contains
    32-bit features or resources. For example, it relies on COM interop
    or calls methods in a 32-bit dynamic link library.

I suspect this is the culprit (seeing you list your machine as Windows
7 64-bit).

Some questions:

1. Are you using the x86 pre-compiled binaries?
   FYI there are some older x64 binaries here:
   http://manageditk.googlecode.com/files/ManagedITK-bin-x64-3.10.0.1.zip
   (I no longer have access to a 64-bit machine, so can't pre-build
these binaries anymore.)

2. Is the .NET program you are calling ManagedITK from the same build
type as the binaries (ie. if using x86 ManagedITK binaries, your
program should be x86, or vice-versa).

3. Perhaps you could post a minimal example (ManagedITK.Common.dll, C#
console program, VS solution/project file)?

Cheers, Dan
