Scaffolding doesn't work when DbContext is in a separate project

Consistently getting this error when attempting to scaffold a controller while having DbContext in a separate project:

There was an error running selected code generator:

'Unable to resolve service for type 
'Microsoft.EntityFrameworkCore.DbContextOptions`1[MyProject.Data.MyProjectDbContext]' 
while attempting to activate 'MyProject.Data.MyProjectDbContext'.'

MyProjectDbContext:

public class MyProjectDbContext : DbContext
{
    public MyProjectDbContext(DbContextOptions<MyProjectDbContext> options) : base (options)
    { }

    public DbSet<Note> Notes => Set<Note>();
}

DbContext is registered in Program.cs as follows:

builder.Services.AddDbContext<MyProjectDbContext>(options =>
    options.UseSqlServer(builder.Configuration.GetConnectionString("MyProjectDbContext")));

Scaffolding works if DbContext moved to the web project.

I found a solution. You can create a dbcontext factory class in same folder with your ApplicationDbContext class. This factory class creates ApplicationDbContext at design time and scaffolding runs correctly.

public class ApplicationDbContextFactory : IDesignTimeDbContextFactory<ApplicationDbContext>
{
        public ApplicationDbContext CreateDbContext(string[] args)
        {
            var optionsBuilder = new DbContextOptionsBuilder<ApplicationDbContext>();
            optionsBuilder.UseSqlServer("Server=(localdb)\\MSSQLLocalDB;Database=EcommerceDb;Trusted_Connection=True;MultipleActiveResultSets=true");

            return new ApplicationDbContext(optionsBuilder.Options);
        }
}

You can use ConfigurationBuilder class for build the configuration.

public class ApplicationDbContextFactory : IDesignTimeDbContextFactory<ApplicationDbContext>
{
    public ApplicationDbContext CreateDbContext(string[] args)
    {
        var configuration = new ConfigurationBuilder()
            .SetBasePath(AppDomain.CurrentDomain.BaseDirectory)
            .AddJsonFile("appsettings.json")
            .Build();
        
        var optionsBuilder = new DbContextOptionsBuilder<ApplicationDbContext>();
        optionsBuilder.UseSqlServer(configuration.GetConnectionString("Default"));

        return new ApplicationDbContext(optionsBuilder.Options);
    }
}
