MVC Exception trough cli dotnet asp-codegenerator

Hi! I'm having troubles to lunch my web service in local host. All code has been builded with CLI and powershell with dotnet asp-codegenerator. This is the error message that shows in the explorer (Google Chrome or IE, both):

`An unhandled exception occurred while processing the request.

My Powershell escript to create the models, views and controller:

`dotnet ef dbcontext scaffold "Server=$Server;Database=$DB;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -o Models

dotnet aspnet-codegenerator controller -name EstadoLineasController -actions -outDir Controllers -m Lineas -dc pruebas_telfContext

dotnet aspnet-codegenerator view EstadoLineas Create -outDir Views -udl -m Lineas -namespace EstadoLineasController `

This is my dependency relation: dotnet add $csproj_name package Microsoft.AspNetCore.Razor.Language -v 2.2.0 dotnet add $csproj_name package Microsoft.Extensions.DependencyInjection -v 2.2.0 dotnet add $csproj_name package Microsoft.Extensions.DependencyInjection.Abstractions -v 2.2.0 dotnet add package Microsoft.VisualStudio.Web.CodeGeneration.Design -v 2.1.1 dotnet add package Microsoft.EntityFrameworkCore.SqlServer -v 2.1.1" dotnet add package Microsoft.EntityFrameworkCore.Tools -v 2.1.1" dotnet add package Microsoft.EntityFrameworkCore.SqlServer.Design -v 2.0.0" dotnet add package Microsoft.EntityFrameworkCore.Relational -v 2.1.1" dotnet add package Microsoft.EntityFrameworkCore.InMemory -v 2.1.1

I know that dotnet core warning to set a version lesss than 2.2.0 by the other way, alert an error and not creates the generators.

Thanks in advance!!!

P.D: Curiosly, when i'm created the app with VS2017, not dotnet console, the app runs fine but not with cli dotnet console... ughhhhh. I need to automathize a the creation of a lot of forms in web.

dotnet / efcore
