Cannot resolve scoped service Microsoft.AspNetCore.Mvc.ViewFeatures.Internal.IViewBufferScope from root provider

Cannot resolve scoped service Microsoft.AspNetCore.Mvc.ViewFeatures.Internal.IViewBufferScope from root provider

This error occurs when you try to resolve a scoped service from the root service provider in an ASP.NET Core application. The Microsoft.AspNetCore.Mvc.ViewFeatures.Internal.IViewBufferScope service is a scoped service, which means that it is only available within the context of a specific HTTP request.

To resolve this error, you need to make sure that you are using the correct service provider. You should not use the root service provider to resolve scoped services. Instead, you should use the service provider that is scoped to the current HTTP request.

In an ASP.NET Core application, you can access the scoped service provider by injecting the IServiceScopeFactory interface and using it to create a new scope. You can then use the scoped service provider to resolve the IViewBufferScope service. Here's an example:

public class MyController : Controller { private readonly IServiceScopeFactory _serviceScopeFactory; public MyController(IServiceScopeFactory serviceScopeFactory) { _serviceScopeFactory = serviceScopeFactory; } public IActionResult MyAction() { using (var scope = _serviceScopeFactory.CreateScope()) { var viewBufferScope = scope.ServiceProvider.GetRequiredService<IViewBufferScope>(); // Your code here } } }

In this example, the MyController class injects the IServiceScopeFactory interface. In the MyAction method, a new scope is created using the CreateScope method of the IServiceScopeFactory interface. The scoped service provider is then retrieved from the scope using the ServiceProvider property, and the IViewBufferScope service is resolved using the GetRequiredService method.

By using the scoped service provider, you can resolve scoped services without getting the "Cannot resolve scoped service" error.
