GetKnownTypes for dynamic known type list

WCF in .Net framework had an overload for ServiceKnownType as follows:

[ServiceKnownType("GetKnownTypes", typeof(DataProviderTypes))]
public interface IService
{
}

public class DataProviderTypes
{
    public static IEnumerable<Type> GetKnownTypes(ICustomAttributeProvider provider)
    {
        List<Type> lst = new List<Type>();
        '
        '
        return lst;
    }
}

This allowed to dynamically generate list of known types.

Is there any way to achieve this ? If not, when is this planned ? Coz this is looking like a showstopper.

Thanks

Yes, a new ServiceKnownTypeTests.cs can be created. Feel free to open a draft PR so that you can get some feedback before you are complete if you would like. I’m happy with reducing the usage of CustomAttributeProvider and relegating it to only being used to get custom attributes including the converting System.ServiceModel variations to CoreWCF ones. I think we could get away with turning it into a static class and making the method an extension method on ICustomAttributeProvider. Probably need to rename it otherwise the ICustomAttributeProvider version of the method would get called instead. I’m open to any cleanup you would like to do, or you can make the minimal changes required. It’s up to you.

That comment is a holdover from very early .NET Standard days when that interface wasn’t available. It wasn’t the reason why that overload wasn’t supported though. It was because this code was originally ported for UWP apps running on .NET Native which didn’t allow reflection and dynamically calling of methods. This can definitely be re-enable. I’ll take a look later to see how much work this will be.
