I just learn to use ASP.NET CORE 2.0 MVC using Visual Studio Community Edition. I want to use MySQL database instead of using SQL Server because I need to use some data inside the old MySQL DB. Please help me solving this problem .. thank you
Here is my error:
Severity Code Description Project File Line Suppression State Error CS1061 'DbContextOptionsBuilder' does not contain a definition for 'UseMySql' and no extension method 'UseMySql' accepting a first argument of type 'DbContextOptionsBuilder' could be found (are you missing a using directive or an assembly reference?) LearnEFCore d:\temp\aspnet\LearnEFCore\LearnEFCore\Startup.cs 29 Active
My code as follow:
In Startup.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.EntityFrameworkCore;
using LearnEFCore.Data;
....
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
var sqlConnectionString = Configuration.GetConnectionString("DataAccessMySqlProvider");
services.AddDbContext<SchoolContext>(options => options.UseMySql(sqlConnectionString));
services.AddMvc();
}
In my appsettings.json
{
"Logging": {
"IncludeScopes": false,
"LogLevel": {
"Default": "Warning"
}
},
"ConnectionStrings": {
"DataAccessMySqlProvider": "server=localhost;port=3306;userid=root;password=root;database=sportstore;"
}
}
In my Models/Data
using LearnEFCore.Models;
using Microsoft.EntityFrameworkCore;
namespace LearnEFCore.Data
{
public class SchoolContext : DbContext
{
public SchoolContext(DbContextOptions<SchoolContext> options) : base(options)
{
}
public DbSet<Course> Courses { get; set; }
public DbSet<Enrollment> Enrollments { get; set; }
public DbSet<Student> Students { get; set; }
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<Course>().ToTable("Course");
modelBuilder.Entity<Enrollment>().ToTable("Enrollment");
modelBuilder.Entity<Student>().ToTable("Student");
}
}
}
My csproj
<Project Sdk="Microsoft.NET.Sdk.Web">
<PropertyGroup>
<TargetFramework>netcoreapp2.0</TargetFramework>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="Microsoft.AspNetCore.All" Version="2.0.0" />
