Where is CountResult defined in this codebase?

[niemyjski]

CountResult comes from this nuget package https://www.nuget.org/packages/Foundatio.Repositories/: and here is the code: https://github.com/FoundatioFx/Foundatio.Repositories/blob/main/src/Foundatio.Repositories/Models/FindResults.cs#L101

It would be nice if it were possible to say include any derived types from a specific interface or any non framework interface that's returned from an api. These all had to be hand created because they couldn't be generated: https://github.com/exceptionless/Exceptionless/blob/main/src/Exceptionless.Web/ClientApp/src/lib/features/shared/models/aggregations.ts

I think I see the issue based on the definition of IAggregate here. It looks like this is a variant of dotnet/runtime#105769. IAggregate defines a custom JSON converter for its behavior and System.Text.Json doesn't emit any schemas for these and has no mechanism for declaring the schema at the moment.
