WPF Snake Game problem

I'm making a snake game which is based on 2 dimensional array and enum type for every element. It can be either GridValue.Empty, GridValue.Snake or GridValue.Food. I'm kinda stuck because by now the snake should be shown when i turn it on but somehow every cell of the grid is empty. If anyone could help me that would be nice cause im stuck on this for like 2 hours. It's nothing complicated and less than 10 mins of debugging but would mean a world to me.!...

Hi, I need some help in WPF/XAML I have a UserControl for a PaginatesTable where I have a couple of WPF controls inside, TextBox, DataGrid, and some buttons for pagination, the main idea of the UserControl is to be reusable, so basically I have some PaginatedTableViewModel<T> which I initialize on each ViewModel of the Views and then I pass an ObservableCollection into PaginatedTableViewModel<T> to render those Objects But I need an approach to customize the DataGrid columns, Because obviously there are different properties on <T>...

Updating/Deleting owned properties with EF Core and AutoMapper

The problem I'm facing is that automapper is not tracking the changes since when i retrive AsNotracking() it wont change anything, but if i remove that, then it complains about the same entity being tracked when i do mapper.map<Entity>(doman), which creates a new entity and EF begins tracking it, I solved it by fetching the entity in the repository and doing mapper.map(entity, domain) so it replaces the one i fetched, but in my command handler I already did the fetch of the entity and did an in place mapping to change its values, how can I avoid re fetching in my repository?...

Would a Declarative Reactive UI be too expensive?

Not 100% sure "reactive" is the right term. But frameworks like Flutter, where they rebuild sections of the UI with light weight objects when there is a state change. Would something like that work well in C#? Thinking of for like UI heavy games? It feels like it would generate a lot of garbage so not really make sense to do. But I also see there is like MAUI Reactor. Which seems to do it. But seems like it wouldn't scale well. And doesn't seem like they are doing any pooling or anything. It is one of those things that are a bit hard to setup a realistic MVP to profile myself....
