I have an asp.net project X which should talk with multiple other asp.net projects Ys. I would like to start them all with Aspire, but I would need to give every instance of Y its own appsettings. Is this a possiblity with Aspire? I saw that I can run a project with different launchprofiles, but I'm not sure how that could help me in my situation. Thanks for the help!

How to access functions in another class in the same namespace?

Hey dudes. I come from a background of Pascal and Lua, so bear with me if this is an obvious question. I've got a big class, and I want to move some of my functions into another one to keep things tidy. But it appears to not be as simple as just making another class in the same namespace, and calling the function from there. That throws the error: An object reference is required for the non-static field, method, or property 'Util.CanMarry(Hero, Hero)' So what's the approach to adding functions that are called by another class? Pic 1: The new helper class with a function in it...

✅ When and when not to use a DTO?

I know you shouldn't really send the exact database model to the client and instead choose only the data that should be sent to the client, but when if you are querying the database for a super specific projection of data, and the DTO would end up looking exactly like that projection. Should you still make the DTO or is it perfectly fine to just return the projection as the response, or query the database directly into the DTO.?

How to manually upgrade a websocket connection (preferably with a popular package like Fleck)

For authentication (this isn't a traditional web server so I planned on not using like ASP.NET, plain console). I'd prefer not creating/managing a websocket connection from scratch, but if there's no other option with C#, i guess ill have to.
