No database provider has been configured for this DbContext

var context = ((IInfrastructure<IServiceProvider>)set).GetService<DbContext>();

在EF Core 1.0 中会出现如下错误

Unhandled Exception: System.InvalidOperationException: No database provider has been configured for this DbContext. A provider can be configured by overriding the DbContext.OnConfiguring method or by using AddDbContext on the application service provider. If AddDbContext is used, then also ensure that your DbContext type accepts a DbContextOptions<TContext> object in its constructor and passes it to the base constructor for DbContext.

解决方案：

var context = ((IInfrastructure<IServiceProvider>)set).GetService<ICurrentDbContext>().Context;

No database provider has been configured for this DbContext
