I can't add view in ASP.NET Core MVC

Using ASP.NET Core 6.0 MVC, I'm attempting to create a web project with an n-tier architecture. I encounter the following issue when attempting to add a view from the Controller. After a few hours of investigation, I was unable to come up with a solution; therefore, I would appreciate your assistance.

Error message:

There was an error running the selected code generator: 'Scaffolding failed. Could not load information for project C:\Users\PC\source\repos\BlogProject\BusinessLayer\BusinessLayer.csproj'

    This Issue relates the Microsoft.VisualStudio.Web.CodeGeneration.Design package. It often caused by using 6.0.9 version, 6.0.8 version and 6.0.0 version.

    It is a know Issue, You can follow this github issue to wait for the response from Microsoft.

    Or you can try to the following methods:

    Method 1:

    1. Remove the Database class library reference from the MVC project

    2. According to the models in the Database class library, create models (use the same name) in the MVC projects.

    3. In MVC projects, you can use Scaffold to add the generate pages with the new created models.

    4. Remove the models from the MVC project and re-add the Database class library project reference. [Note] You need to change the model reference in the generated page.

    Method 2:

    You can also create a new project which contains the MVC and Database models(put them in the same project), then generate the page using Scaffolded, after that you can copy the generated page to the original/main project.

    Method 3

    Try to downgrade the Asp.net 6 application to Asp.net 5(remember to downgrade the relates package, especially the Microsoft.VisualStudio.Web.CodeGeneration.Design package), then use Scaffold to generate the related views, after that migration the application from Asp.net 5 to Asp.net 6.
