Code before the changes:

List<ProductBrandModel> model = brands.Select(item => Mapper.Map<ProductBrand, ProductBrandModel>(item)).ToList();

Code after the improvement:

List<ProductBrandModel> model = brands.Select(Mapper.Map<ProductBrand, ProductBrandModel>).ToList();

    Since you’re directly passing the parameter of the lambda expression to the Mapper.Map method, it is exactly equivalent to specifying this method directly as the projection for Select. The signature of Mapper.Map is compatible with the Func<TSource, TResult> delegate, so R# suggests to use the method group directly rather than a lambda expression.
