Invalid Message Channel Generator

[GenerateInvalidMessageChannel] creates a strongly typed builder factory for InvalidMessageChannel<TPayload>.

[GenerateInvalidMessageChannel(
    typeof(OrderImportCommand),
    FactoryName = "Create",
    ChannelName = "order-import-invalids")]
public static partial class GeneratedOrderInvalidMessageChannel;

Generated shape:

public static InvalidMessageChannel<OrderImportCommand>.Builder Create(
    MessageChannel<InvalidMessage<OrderImportCommand>> invalidChannel);

The host type must be partial. Applications finish the builder with validation predicates and reason functions from their own domain.
