This is a somewhat undocumented function but if you are familiar with the class BusinessManager in the Mediachase.BusinessFoundation.Data.Business namespace things become quite easy. To demonstrate this I created a customer called Test Testson
Snippet
To remove this customer contact programmatically with c# the following code is required
// Fetch the user Mediachase.Commerce.Customers.CustomerContext customerContext = new Mediachase.Commerce.Customers.CustomerContext(); Mediachase.Commerce.Customers.CustomerContact testTestson = customerContext.GetContactById(new Guid("1c8279d8-85bd-4063-a018-a627f98c99cb")); // Delete Mediachase.BusinessFoundation.Data.Business.BusinessManager.Delete(testTestson);
