I have a project that can build fine on my local machine, however, when I get TFS to build it, I receive the following error –

SGEN: An attempt was made to load an assembly with an incorrect format:

After reading through many other posts here on this topic, most people just say I need to change the build type to either x86 or Any CPU, rather than x64, but after trying countless combinations, this was not the solution. My program is also a windows service, so setting the App Pool to allow 32 bit applications (as suggested by others) is also not the solution.

    My problem was finally solved by this page – http://aplocher.wordpress.com/2012/10/12/sgen-an-attempt-was-made-to-load-an-assembly-with-an-incorrect-format-tfs-2010/

    Just in case that page ever disappears in the future, here are the steps involved –

    1. In Team Explorer, right click on your Build Definition and choose Open Process File Location
    2. Double click on the XAML file that is selected
    3. In the designer, select the container called Sequence (this is the top-level container that goes around everything else).
    4. In the Arguments list (typically at the bottom), change MSBuildPlatform from Microsoft.TeamFoundation.Build.Workflow.Activities.ToolPlatform.Auto to Microsoft.TeamFoundation.Build.Workflow.Activities.ToolPlatform.X86.
    5. Save and close the file.
    6. Check the file back in to TFS and try your build again.
