### Describe the bug

I'm creating a new project using `.NET MAUI Blazor Hybrid and Web App` with `.NET9`. I want to add `Identity` to the project. To do so, right-click on the web project, select **Add** and then **New Scaffolded Item** and then select *Blazor Identity* from the window.

Then, I select all the dropdown lists with the default values.

After clicking *Add*, I get this error

What do I have to do in order to add *Identity* to my project? Is it better if I copy a n old implementation?
