namespace MvcMovie.Data not generated by dotnet-aspnet-codegenerator command

ethanhou-MSFT commented 2 years ago

Hi,

I'm trying to follow the guideline using VScode but failed to continue on the MVC chapter part5.

The result of this command is different from the result in visual studio:

namespace MvcMovie.Data will not be generated in Data/MvcMovieContext.cs and using MvcMovie.Data; will not be generated in program.cs neither if I use the above command, it will also block me from following the guideline of next chapter since some compiling issues will be introduced to the project.

What NS is generated? You need to run this command from the project folder.

Hi @Rick-Anderson ,

Thanks for your reply. I can guarantee I run that command in the project folder with Program.cs.

No namespace was generated in the MvsMovieContext.cs, I know it sounds weird but here is what I got:

Data\MvcMovieContext.cs

#nullable disable
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.EntityFrameworkCore;
using MvcMovie.Models;

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

        public DbSet<MvcMovie.Models.Movie> Movie { get; set; }
    }

Program.cs

using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.DependencyInjection;
var builder = WebApplication.CreateBuilder(args);

builder.Services.AddDbContext<MvcMovieContext>(options =>
    options.UseSqlite(builder.Configuration.GetConnectionString("MvcMovieContext")));

// Add services to the container.
builder.Services.AddControllersWithViews();

var app = builder.Build();

// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Home/Error");
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();
}

app.UseHttpsRedirection();
app.UseStaticFiles();

app.UseRouting();

app.UseAuthorization();

app.MapControllerRoute(
    name: "default",
    pattern: "{controller=Home}/{action=Index}/{id?}");

app.Run();

Try

dotnet tool uninstall -g dotnet-aspnet-codegenerator
dotnet tool install -g dotnet-aspnet-codegenerator

ethanhou-MSFT commented 2 years ago

Try

dotnet tool uninstall -g dotnet-aspnet-codegenerator
dotnet tool install -g dotnet-aspnet-codegenerator

I tried that two commands and get the same result. For your convenience I will paste my log here:

BTW, does that series of commands work for you? If yes, it's okay to close this issue since I can continue with Visual Studio instead of VScode and I just want to make sure the tutorial is up to date :)

MattMorris247 commented 2 years ago

I have this exact same issue. Those 2 lines Rick recommended did not change anything. I cannot continue in the tutorial because it relies on using MvcMovie.Data , however it states the namespace of it does not exist.

Hi @MattMorris247 , yes this is an issue, I don't know why they still close this issue without verifying it. My suggestion is follow the Visual Studio track, at least using Visual Studio to redo the related sections, that will help you skip this issue and I've already tested.

sadullahcihan commented 2 years ago

I am also having the same issue. I could not fixed it yet.

edwestfieldjr commented 2 years ago

I was able to get it to work with these steps:

I replaced my Data/MvcMovieContext.cs file with the code found in this section, which declares the MvcMovie.Data namespace
I then added using MvcMovie.Data; to every csharp file that referenced the MvcMovieContext class
It would still crash with the error: SQLite Error 1: 'no such table: Movie', so I had to manually create the table in DB Browser for SQLite:

CREATE TABLE "Movie" (
    "ID"    INTEGER NOT NULL,
    "Title" TEXT,
    "ReleaseDate"   TEXT NOT NULL,
    "Genre" TEXT,
    "Price" TEXT,
    PRIMARY KEY("ID")
)

Once the table it ran and the Movies/Index page came up:

This is my first go‘round writing in C# and building a .NET MVC App, so I'm going to continue on with this Microsoft tutorial before going back and debugging further to see why the table did not generate on its own.

Current Working Environment:

.NET v6.0.401 (macOS)

VSCode v1.72.0 (macOS)

Chrome v105.0.5195.125 (x86_64)

MacOS Monterey 12.6
