I am getting System.BadImageFormatException : The operating system cannot run exception while running unit tests

I am working on a Winforms project. Currently I am facing a problem that running some of the test cases throw 

    System.BadImageFormatException : The operating system cannot run . 
(Exception from HRESULT: 0x800700B6)

exception. This happens only if I run tests through NUnit. However, if I run the application through the code, it works fine.

Remoting is being used in the application. Can that be an issue?

I had similar issue but in my case configuration file for application helped . This file contained following entries:

<configuration>
    <startup useLegacyV2RuntimeActivationPolicy="true">
        <requiredRuntime version="v4.0" />
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0" />
    </startup>
</configuration>

Make sure both NUNIT and your code are compiled to the same platform - x86 or x64. The easiest thing to set the platform to 'Any CPU' on your code.
