> Thanks to [Masoud Nazari](https://github.com/MAS-OUD) for raising this [issue on 1 March 2023](https://github.com/markjprice/cs11dotnet7/issues/33).
In Step 1, you are told to add a new class library project named `PacktLibraryModern`.
In Step 4, in the `PeopleApp` console app project, you are told to create an instance of the `Book` class that is defined in the class library. To do so, you must have added a reference to the `PacktLibraryModern` project.
In the next edition, I will add steps before Step 4 to remind readers how to do this, as shown below:
*If you are using Visual Studio 2022:*
- In **Solution Explorer**, select the `PeopleApp` project, navigate to **Project** | **Add Project Reference…**, check the box to select the **PacktLibraryModern** project, and then click **OK**.
*If you are using Visual Studio Code:*
- Edit `PeopleApp.csproj` to add a project reference to `PacktLibraryModern`, as shown in
the following markup:
```xml
<ItemGroup>
<ProjectReference Include="../PacktLibraryModern/PacktLibraryModern.csproj" />
</ItemGroup>
```
- Build the `PeopleApp` project.
