CS0246: The type or namespace name "ProductDto" could not be found(are u missing a using directive or an assembly reference?)

Question

hey anyone give me the solution of this issue https://github.com/GavinLonDigital/ShopOnlineSolution/issues/1

Answer 1

I guess that you copied the source code written by somebody else and the definition of ProductDto class is included somewhere else. If so please find the source code that include the definition of ProductDto class.

I understand that the Dto stands for Data Transfer Object as described in the following Microsoft document:

Create Data Transfer Objects (DTOs)
https://learn.microsoft.com/en-us/aspnet/web-api/overview/data/using-web-api-with-entity-framework/part-5

It is likely defined in a separate .cs file.

Hi @DEBASIS PAUL (Zhýralý Pāvils) #BlackLivesMatter ,

CS0246: The type or namespace name "ProductDto" could not be found(are u missing a using directive or an assembly reference?)

If you check the Yotube video or check the source code, you can see that in the solution, there have three projects: ShopOnline.Api, ShopOnline.Models and ShopOnline.Web.

The ProductDto class was in the ShopOnline.Models project, and in the ShopOnline.Api and ShopOnline.Web project, they will add the ShopOnline.Models project reference.
For example, in the ShopOnline.Web project, right click the Dependencies option => click the Add Project Reference... => in the popup window select the ShopOnline.Models project => Finally, click the Ok button. Then, in the ShopOnline.Web project, you can add the ShopOnline.Models project reference:

Hi, Check your Web(ShopOnline.Web) project references and add the Model project in the references. Maybe you are missing to add model project (ShopOnline.Models) in ShopOnline.Web project.
