Some unit tests fail since my “upgrade” to Windows 8 64 bit coming from a 32 bit installation. The exception is shown below

System.BadImageFormatException: Could not load file or assembly ‘XXX SQLite’ or one of its dependencies. An attempt was made to load a program with an incorrect format.

I changed the Hosts setting as described here and everything works fine again.

The unit tests that failed were integration tests. Changing the environment should not have this impact on regular unit tests!
