How to get aspire and marten to play along?

[mastoj]

I have read the post here: https://jeremydmiller.com/2024/05/01/marten-postgresql-and-net-aspire-walk-into-a-bar/, and think I do sort of the same thing, but it does not work. I'm working on a proof of concept for a application using orleans, marten and also aspire for local development. My config for marten can be seen here: https://github.com/mastoj/monostore/blob/16a58b050e476571d450ede90a903bd90204fba3/src/cart/MonoStore.Cart.Module/ApiExtensions.cs#L63-L84.

The exception I get when starting the AppHost is:

Unhandled exception. Npgsql.NpgsqlException (0x80004005): Exception while reading from stream

Any ideas or suggestions on what might be wrong?

Very odd, but now it is working... not sure why though.
