VS2017添加EF的MVC控制器报错的解决方法，供大家参考，具体内容如下
1. 错误描述：no database provider has been configured fot this DbContext.
此类错误是上下文的注册造成的.解决方式在DBContext中重写OnConfiguring方法去注入数据库连接.
DbContext中:
public static string ConnectionString { get; set; }
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
optionsBuilder.UseSqlServer(ConnectionString);
base.OnConfiguring(optionsBuilder);
}在Startup.cs中
public void ConfigureServices(IServiceCollection services)
{
// Add framework services.
var sqlserverConnection = Configuration.GetConnectionString("SQLServerConnection");
DbContext.ConnectionString = sqlserverConnection;//将配置连接传入DbContext中
services.AddDbContext(options => options.UseSqlServer(sqlserverConnection));
services.AddMvc();
} 2.错误描述：Could not add Model type XXX to DbContext
错误描述没有注册DbSet属性.但实际上是有 public DbSet
