Mixing code generators doesn't work

I have a project where I'm defining the SignalR details from a spec using Roslyn code generation. I'm making the hub interface dynamically. Unfortunately the CLI tool doesn't seem to see it- even if I use the --asm true option- I figured that would be enough to make it look at the final output. Is there something else I can do? I'd love to make this work.

Here is the code being generated - if it isn't obvious, this is the code I'm generating. (snipped for clarity and I've omitted the generated implementation)

[Hub]
public interface IAcquisitionDataHub
{
        Task<bool> ShowActive();
        Task<int[]> ShowData(int start = default, int length = default);
        Task<int> ShowGainCoarse();
        Task<double> ShowGainFine();
        Task<int> ShowHighVoltageActual();
        Task<int> ShowHighVoltageTarget();
        Task<long> ShowIntegral(int startchannel = default, int endchannel = default);
        Task<string> ShowVersion();
        Task SetGainCoarse(int gainvalue);
        Task SetGainFine(double gainvalue);
        Task SetHighVoltage(int voltage);
        Task SetRoi(int startchannel, int endchannel);
        Task EnableHighVoltage();
        Task DisableHighVoltage();
        Task Start(int segmentmask = default);
        Task Stop();
        Task Clear();
}

[Receiver]
public interface IAcquisitionDataHubReceiver
{
    Task ReceiveAcquisitionData(int[] data, int startIndex); 
    Task ReceiveOscilloscopeData(int[] data);
        Task OnSetGainCoarse(int gainvalue);
        Task OnSetGainFine(double gainvalue);
        Task OnSetHighVoltage(int voltage);
        Task OnSetRoi(int startchannel, int endchannel);
        Task OnEnableHighVoltage(string message);
        Task OnDisableHighVoltage(string message);
        Task OnStart(string message);
        Task OnStop(string message);
        Task OnClear(string message);
}

This is the file that got generated by dotnet tsrts --project Project.csproj --output generated --asm true:

/* eslint-disable */
/* tslint:disable */
// @ts-nocheck
import type { HubConnection, IStreamResult, Subject } from '@microsoft/signalr';


// components

export type Disposable = {
    dispose(): void;
}

export type HubProxyFactory<T> = {
    createHubProxy(connection: HubConnection): T;
}

export type ReceiverRegister<T> = {
    register(connection: HubConnection, receiver: T): Disposable;
}

type ReceiverMethod = {
    methodName: string,
    method: (...args: any[]) => void
}

class ReceiverMethodSubscription implements Disposable {

    public constructor(
        private connection: HubConnection,
        private receiverMethod: ReceiverMethod[]) {
    }

    public readonly dispose = () => {
        for (const it of this.receiverMethod) {
            this.connection.off(it.methodName, it.method);
        }
    }
}

// API

export type HubProxyFactoryProvider = {
}

export const getHubProxyFactory = ((hubType: string) => {
}) as HubProxyFactoryProvider;

export type ReceiverRegisterProvider = {
}

export const getReceiverRegister = ((receiverType: string) => {
}) as ReceiverRegisterProvider;

// HubProxy


// Receiver

I'm making the hub interface dynamically.

It is impossible to support interfaces that are dynamically generated at runtime.
hub/receiver interfaces must be defined at compile time.
