我正在使用MySql
作爲官方連接提供程序的數據庫。我的下一個項目例如在MAC嘗試它(asp.net 1.0核心):Dot Net Entity Framework數據庫更新不會在mysql數據庫中創建表
public class BloggingContext : DbContext
{
public BloggingContext(DbContextOptions<BloggingContext> options)
: base(options)
{ }
public DbSet<Blog> Blogs { get; set; }
public DbSet<Post> Posts { get; set; }
}
public class Blog
{
public int BlogId { get; set; }
public string Url { get; set; }
public List<Post> Posts { get; set; }
}
public class Post
{
public int PostId { get; set; }
public string Title { get; set; }
public string Content { get; set; }
public int BlogId { get; set; }
public Blog Blog { get; set; }
}
在我Startup.cs
public void ConfigureServices(IServiceCollection services)
{
var connection = @"server=localhost;userid=efcore;port=3306;database=blogsFinal;sslmode=none;";
services.AddDbContext<BloggingContext>(options => options.UseMySQL(connection));
// Add framework services.
services.AddMvc();
}
在我project.json我還加
"dependencies": {
...
"MySql.Data.EntityFrameworkCore": "7.0.5-ir21",
"Microsoft.EntityFrameworkCore.Tools": {
"version": "1.0.0-preview2-final",
"type": "build"
}
}
和
"tools": {
...,
"Microsoft.AspNetCore.Server.IISIntegration.Tools": "1.0.0-preview2-final"
},
當我運行dotnet ef migrations add v1
,工作正常,並創建遷移文件,但是當我執行dotnet ef database update
創建數據庫表,但並沒有引發此輸出

能否請您發表這是執行的代碼表示更新,這是拋出錯誤? – A3006
這是代碼[鏈接](https://github.com/careuno/newtestEfcoreMysql)錯誤是當我執行dotnet ef數據庫更新 –
