c# - Automapper Ignore Auto Flattening -

i have entity in legacy system has format

public guid id {get;set;} public int duration {get;set;} public bool durationtype {get;set;} 

in viewmodel have following

public guid id {get; set;} public int duration {get;set;} 

mapping entity view model works fine, when try , map viewmodel entity dies.

what appears doing trying call non existing property duration.type in reverse mapping (i.e it's trying auto-flatten). results in error cannot map int32 bool.

does have suggestions on how disable auto-flattening in automapper or manually set fields maps happen using attributes.

to have ignore durationtype property when mapping viewmodel entity add mapping configuration:

mapper.createmap<viewmodel,entity>()       .formember(dest => dest.durationtype, options => options.ignore());
