X01.SportWeb: An Example for AspNetCore 2.0,

When the new one comes, the old one will be forgotten. Learning AspNet Core 2.0 is painful without a good example. SportsStore in Pro ASP. NET Core MVC 2 is worth reading. You may wish to download and study it:

Preparation

1. UseUbuntuSystem

2. InstallationNetCore2.0

3. InstallVSCode

4. InstallationSqlite

Start work

1. Create a folder named MvcLab and open it with VSCode,ALT +', Open the terminal, enter the commandDotnet new slnGenerate a solution. Then enter the following command to generate x01.SportWeb and Its Test Project:

    mkdir x01.SportWeb 　　cd x01.SportWeb/　　dotnet new mvc --auth Individual　　cd ..　　mkdir x01.SportTest　　cd x01.SprotTest/　　dotnet new xunit　　cd ..　　dotnet sln add x01.SportWeb/x01.SportWeb.csproj　　dotnet sln add x01.SportTest/x01.SportTest.csproj    

2. Compare with the example of SportsStore.

Additional instructions

1. Use Ubuntu for cross-platform access. The -- auth Individual option is used to prepare for user management.

2. In x01.SportTest. csproj, add a reference to x01.SportWeb. csproj:

  <ItemGroup>    <ProjectReference Include="../x01.SportWeb/x01.SportWeb.csproj" />  </ItemGroup>

3. InApplicationDbContextAddPublic DbSet <Product> Products {get; set :}After properties, run the following command:

dotnet ef migration add AddProduct

Before updating the database, you must add the TempDbContextFactory class as follows:

using Microsoft.EntityFrameworkCore;using Microsoft.EntityFrameworkCore.Design;namespace x01.SportWeb.Data{    public class TempDbContextFactory : IDesignTimeDbContextFactory<ApplicationDbContext>    {        public ApplicationDbContext CreateDbContext(string[] args)        {            var builder = new DbContextOptionsBuilder<ApplicationDbContext>();            builder.UseSqlite("Data Source=app.db");            return new ApplicationDbContext(builder.Options);        }    }}

Manually annotate Migrations /*_AddProductAddForeignKey in. cs:

　　　　　　　// migrationBuilder.AddForeignKey(            //     name: "FK_AspNetUserTokens_AspNetUsers_UserId",            //     table: "AspNetUserTokens",            //     column: "UserId",            //     principalTable: "AspNetUsers",            //     principalColumn: "Id",            //     onDelete: ReferentialAction.Cascade);

Run the following command to update the database:

  dotnet ef database update

Other languages in the book "Pro ASP. NET Core MVC 2" are quite detailed.
