It's possible to use Web.config Transformations for App.config files through a workaround.

You simply have to invoke the appropriate MSBuild tasks at the right stage in your build process.
Add this code snippet to your project file:

    
    
    
    
        
        
            $(TargetFileName).config
        
    

Then add additional App.config files to your project for each build configuration where you wish to apply a transformation. For example:

    
    
        App.config
