OK, by removing all copies of \bin\System.Web.\* from my app’s  
path, I  
whittled the exception down to this:

Handling exception type TypeInitializationException  
Message is An exception was thrown by the type initializer for  
System.Web.Configuration.WebConfigurationManager  
IsTerminating is set to True  
System.TypeInitializationException: An exception was thrown by the type  
initializer for System.Web.Configuration.WebConfigurationManager
