WithPerTenantOptions overload allowing dependency injection?

[Bouke]

In order to use dependency injected services while configuring services, you'd normally inherit from IConfigureNamedOptions or IConfigureOptions and register a singleton like this:

services.AddSingleton<IConfigureOptions<CookieAuthenticationOptions>, MyConfiguration>();

Inside MyConfiguration I can have dependencies injected:

    class MyConfiguration : IConfigureOptions<CookieAuthenticationOptions>
    {
        private IDataProtectionProvider dp;

        public GatewaySessionConfiguration(IDataProtectionProvider dp)
        {
            this.dp = dp;
        }

        public void Configure(CookieAuthenticationOptions options)
        {
            options.TicketDataFormat = TicketDataFormat(dp.CreateProtector("on purpose"));
        }
    }

With the current WithPerTenantOptions<CookieAuthenticationOptions> I cannot achieve the same. The data protector is only instantiate later on in the pipeline and I cannot grab a reference to it in ConfigureServices.

Hi, I think I see what you mean -- you want to access DI from within the lambda inside WithPerTenantOptions right?

I will have to add this but I have a workaround that will be available before .NET 6 comes out.

One thing you could try for now is to implement ITenantConfigureOptions<TOptions, TTenantInfo> and inject into the ctor there. Keep in mind it registers as singleton so any DI you do should not be for scoped services.

The interface is not public, so I cannot implement it:

Finbuckle.MultiTenant/src/Finbuckle.MultiTenant/Options/ITenantConfigureOptions.cs

Line 6 in e0c88b0

interface ITenantConfigureOptions<TOptions, TTenantInfo>

OT: Are you interested in a PR adding support for a Named variant, similar to IConfigureNamedOptions<T>?

[AndrewTriesToCode]

You are right it is not public! I will change it to public for the next release which will be for .Net 6 in November at the latest.

Regarding support for names options- yes this is on my todo list and probably will come shortly after the .NET 6 release. If you want to take a stab at it and submit a PR please do so.

I just released 6.4.2 on nuget.org which makes this a public interface. Thanks for your patience.

Named options added to the latest release. Cheers.
