How to use injected service from razor layout view in child view

Question

Just learning about injected services in asp.net core razor views. But I haven't been able to find out how to use a service that is injected in the layout view (will be used by many views), in child views.

Maybe something conceptually like this:

Layout View

@inject IOptions<PortalConfiguration> OptionsPortalConfiguration

<some HTLM markup>
@RenderBody(OptionsPortalConfiguration) <--pass it here???

Child View

Not sure how to reference it.

Answer 1

Another approach for that kind of situations would be to create static helper methods, which can be called in all views without injection.

public static class TestHelperExtensions
{
    public static ITestProvider TestProvider { get; set; }

    public static string Get(this ITestHelper html, string arg)
    {
        return TestProvider.Get(arg);
    }
}
