I created a C++/CLI assembly that creates a wrapper around native C++ code. The resource compiles and the assembly loads fine into my C# project when I add it as a resource. I can access my objects and intellisense from within my application, but when attempting to build, it crashes with the exception:
BadImageFormat
Could not load file or assembly
'MyCLI, Version=1.0.3680.28432,
Culture=neutral, PublicKeyToken=null'
or one of its dependencies. An attempt
was made to load a program with an
incorrect format.
I load it into my form load event:
MyCLI.myCLI z;
… and when I compile, it crashes on this line in my main constructor in C#
Application.Run(new Form1());
Does anyone have an idea of what could be causing this exception?
Thanks

You are trying to run this code on a 64-bit operating system. Your C# code will get nicely compiled to 64-bit machine code. But you'll hit the wall when it tries to load a 32-bit C++/CLI assembly.
In the C# project, use Project + Properties, Application tab, Platform Target = x86. Creating a 64-bit version of your C++/CLI assembly is possible too, use Build + Configuration Manager. Using Platform Target is the better solution.
