Configuration doesn't work with Dependency Injection

I’ve registered IMailChimpManager in the Startup class (MVC Core) And tried to configure the Api key like someone suggested on another issue:

services.AddScoped<IMailChimpManager, MailChimpManager>();
serviceProvider.GetService<IMailChimpManager>().Configure(x => x.ApiKey = "MyKey");

Then tried to add a member:

var member = new Member { EmailAddress = "email", StatusIfNew = Status.Subscribed };
await _mailChimpManager.Members.AddOrUpdateAsync(listId, member);

But I’m stil getting this error ‘Invalid URI: The hostname could not be parsed.’ This means that I didn’t configure the api-key correctly. Any ideas how to do it with dependency injection in MVC Core?

You should never need to register the dependencies like this, you can just use the convenience method like below.

services.AddMailChimpClient("MyKey");

@juliavi are you using Autofac?

I have the same issue: .AddMainChimpClient() cannot be found even when I add using MailChimp.Net; I think the problem is that the extension is available under this directive:

#if NET_CORE

And .NET 7 doesn’t appear to be considered NET_CORE when the constant is defined:

    <PropertyGroup Condition="'$(TargetFramework)' == 'netstandard1.3' Or '$(TargetFramework)' == 'netstandard1.4' Or '$(TargetFramework)' == 'netstandard1.5' Or '$(TargetFramework)' == 'netstandard1.7' Or '$(TargetFramework)' == 'netstandard1.8' Or '$(TargetFramework)' == 'netstandard1.9' Or '$(TargetFramework)' == 'netstandard2.0' Or '$(TargetFramework)' == 'netcoreapp1.0' Or '$(TargetFramework)' == 'netcoreapp1.1' Or '$(TargetFramework)' == 'netcoreapp2.0' Or '$(TargetFramework)' == 'netcoreapp2.1' Or '$(TargetFramework)' == 'netcoreapp2.2'">
        <DefineConstants>NET_CORE</DefineConstants>
    </PropertyGroup>

The parameterless constructor is not available for DI.

How should we register IMailChimpManager in a DI container? Thank you.
