For first I write Extension method for IHTTPController like this:
code :
public static void SetCredentialsToRepository(this IHttpController controller, string technician, string secret);
public void SetCredentialsToRepository(string technician, string secret)
{
    _repository.SetCredentials(technician, secret);
}
actionContext.ControllerContext.Controller.SetCredentialsToRepository(username, secret);

around this issue I was wrong about the issue, it wasn't an IoC and DbContext issue. Seems like it was in the .NET platform itself
https://github.com/dotnet/corefx/issues/9846#issuecomment-274707732
code :
  <dependentAssembly>
    <assemblyIdentity name="System.ComponentModel.TypeConverter" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-4.0.1.0" newVersion="4.0.0.0" />
  </dependentAssembly>

this one helps. Close but no cigar. You are calling your filter with the wrong parameters. You already are calling it as a TypeFilterAttribute, since you need DI and arguments passed in.
Now you just need to fix your arguments. You want to pass in a string array, but you pass in several strings.
code :
[TypeFilter(typeof(AuthorizeFilter), 
    Arguments = new object[] {
        new string[] { PolicyName.CanUpdateModule,  PolicyName.CanReadModule }
    }
)]
public async Task<IActionResult> PutModule([FromRoute] Guid id, [FromBody] Module module) {
    /*do stuff*/
}
public class AuthorizeFilter : ActionFilterAttribute
{
    private readonly IAuthorizationService _authService;
    private readonly string[] _policyNames;

    public AuthorizeFilter(IAuthorizationService authService,string[] policyNames)
    {
        _authService = authService;
        _policyNames = policyNames;
    }
    /* ... */
}

will help you There's two possible approaches. First, you can simply call a partial in your layout:
code :
<partial name="_HeaderExtra" />
@await RenderSectionAsync("HeaderExtra", required: false)
@section HeaderExtra
{
    <!-- add something here -->
}
@section HeaderExtra
{
    @await RenderSectionAsync("HeaderExtra", required: false)
    <!-- add something here -->
}

it helps some times AddDbContext adds a DbContext as scoped by default, which would cause problems with the singleton repositories.
code :
services.AddScoped<IItemRepository, ItemRepository>();
services.AddScoped<IUserRepository, UserRepository>();
