The Ignore method of the FluentMappingBuilder class allows you to specify a class or complex type to exclude from the mapping generation process.
builder.Ignore<ProductCategory>(); builder.Ignore(typeof(ProductCategory)); builder.Ignore(Type.GetType("CrmDemoContext.ProductCategory")); var types = Assembly.GetCallingAssembly() .GetTypes() .Where(type => type.Namespace == "UserNamespace"); builder.Ignore(types);
