Injecting DbContext into FileProvider in ASP.NET Core

I am trying to load some of the views from the database as described in here. So I want to use EF Core in the File provider.

RazorViewEngineOptions has a FileProviders property that you can add your file provider to. The problem is that you have to give it an instace of the file provider. So you'll need to instantiate all of the file providers' dependencies right there in Startup's ConfigureServices method.

Currently I inject an instance of IServiceProvider into the Configure method of Startup. Then I store the instance in a field (called _serviceProvider):

IServiceProvider _serviceProvider;
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory, IServiceProvider provider)
{
   _serviceProvider = provider;
   ...
}

Then in ConfigureServices I use that field to instanciate the UIDbContext.

services.Configure<RazorViewEngineOptions>(options =>
{
    var fileProvider = new DbFileProvider(_serviceProvider.GetService<UIDbContext>());
    options.FileProviders.Add(fileProvider);
});

Is there any better way to be able to inject the UIDbContext into the DbFileProvider constructor Or any way to instantiate a UIDbContext inside DbFileProvider without IServiceProvider?
