[FromKeyedServices("keyName")] Keyed services support in Microsoft.Extensions.DependencyInjection is not resolving dependency in constructor

[nitish-kaushik]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

I am trying the new Support for keyed services in minimal APIs, MVC, and SignalR feature in Asp.Net Core Web API Controller. The dependency works fine when I resolve them directly in the action method of the controller but throws an exception if resolve it in the controller constructor.

Here is my code:

public interface IEmployee
{
    string GetMessage();
}

public class Employee : IEmployee
{
    public string GetMessage()
    {
       return "Hello from Employee";
    }
}

public class TempEmployee : IEmployee
{
    public string GetMessage()
    {
        return "Hello from Temp Employee";
    }
}

And this is how I have registered them in the program.cs class.

builder.Services.AddKeyedSingleton<IEmployee, Employee>("employee");
builder.Services.AddKeyedSingleton<IEmployee, TempEmployee>("tempEmployee");

Here is the code from the Controller:

This works fine if resolving the dependency directly in the method

[HttpGet("temp")]
public ActionResult GetTempEmployee([FromKeyedServices("tempEmployee")] IEmployee tempEmployee)
{
    return Ok(tempEmployee.GetMessage());
}

But If I try to inject this dependency in the constructor then get the error:

[ApiController]
[Route("[controller]")]
public class EmployeeController : ControllerBase
{
    private readonly IEmployee tempEmployee;

    public EmployeeController([FromKeyedServices("tempEmployee")] IEmployee _tempEmployee)
    {
        tempEmployee = _tempEmployee;
    }

    [HttpGet("temp")]
    public ActionResult GetTempEmployee()
    {
        return Ok(tempEmployee.GetMessage());
    }
}

Error:

[BrennanConroy]

It looks like ActivatorUtilities.CreateFactory doesn't have support for FromKeyedServices. This will affect both MVC and SignalR for the constructors of Controller and Hub respectively (when using FromKeyedServices).

I'm checking with folks to see if we just missed support for that.

[nitish-kaushik]

@BrennanConroy Please check for IKeyedServiceProvider too. This is also throwing the same exception in the constructor.

Here is the code

public class ValuesController : ControllerBase
{
    public readonly IKeyedServiceProvider keyedServiceProvider;

    public ValuesController(IKeyedServiceProvider _keyedServiceProvider)
    {
        keyedServiceProvider = _keyedServiceProvider;
    }
   
    [HttpGet("permanent")]
    public ActionResult GetEmployee()
    {
        var ss = keyedServiceProvider.GetRequiredKeyedService<IEmployee>("tempEmployee");
        return Ok(ss.GetMessage());
    }
}

Exception:

Unable to resolve service for type 'Microsoft.Extensions.DependencyInjection.IKeyedServiceProvider' while attempting to activate 'WebApplication5.Controllers.ValuesController'.

[benjaminpetit]

IKeyedServiceProvider is not resolvable with DI, you have to use SIServiceProvider directly

Transfering the issue in runtime.

The issue is that ActivatorUtilities.CreateFactory doesn't support the [FromKeyedService] attribute.
