c# API + angular front end

Hi, This is more of a design question... I have a web api written in C# and a front end writtein in angular. The web api has a settings file associated with it. The web api and front end are both served by kestrel (same port). The front end has some settings as well (in the assets folder). One setting, for example, for the front end is a theme. The theme can be changed using the front end, where it makes a request to the API to set the theme setting....

Query Rider TODO etc. comments for a solution, project, or file into console output

The TODO list Tool Window is very useful, but I would very much like the ability to pull that list into a markdown file as tasks for an Obsidian markdown note. Any ideas on how to do this, or must I copy the TODO patterns and filters into my SourceReporting Roslyn based app and apply the filters to all comments in a CSharpSyntaxNode or something?

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.?
