UUID v4 vs v7
Hi,
I had a model which primary key was type of
long and it was used as cursor for pagination. This way I could simply do the following LINQ query: query.Where(l => l.Id >= queryParams.Cursor).
I switched from long to Guid and I think this is no longer a good solution.
...HttpListenerResponse
I am using a .net HttpClient and HttpListener to communicate between two machines. I have trouble configuring the httpListenerResponse correctly. Whatever I tried so far, the HttpReponseMessage that my HttpClient receives always has an empty ContentEncoding header.
I need to somehow communicate the encoding of the response back to the client. I could also use the request encoding as a workaround but I would rather avoid that...
Best practice reading from `Socket` / `NetworkStream`?
I've got a C# application in which I want to read data from a Unix domain socket (on the sending side I have a Java application which sends buffered data). I want to read all data into a
MemoryStream, as I subsequently want to parse that using CborReader (unfortunately I didn't find any way getting the CborReader itself to read the data directly from the socket).
Now, to my question: I can't figure out what the best practice should be for fully reading the data from the Unix domain socket into a MemoryStream. My tests indicate that I can't rely solely on NetworkStream.DataAvailable but also need to call Socket.Poll(), so I've come up with the following code:
```csharp...Delegate with Task problem
I decided to work with delegates. I chose to do different kinds of sorting. I made a Sort class, where the name and the SortMethod response are located, but when I started to look at the results, I saw that the sorting that was not performed until that moment of output is simply not output (an error appears on result = null). Does anyone know why var result = await sortDelegate.SortMethod; doesn't work?

Easiest way to serialize System.Numerics.Vector3 using System.Text.Json (.NET 8)
I'm writing a 3D level editor in .NET and OpenGL and need level data to be stored as human-readable text, so I'm using System.Text.Json. Since
Vector3 exposes its data as fields instead of properties, it always gets serialized as {}:

Hi everyone,
Hope you're having a fantastic day. I just finished the book "C# the player's guide" and I've enjoyed it immensely. I'm also getting my MS in CS so I'm a little bit familiar with coding and doing projects. I've been self learning for a couple of years and have taken it seriously for the past 6 months. I'm doing Java projects In uni and use python for leetcode and scripting.
My main weakness/problem right now is that I don't know how to design software. Like when should something be a new class? when should I use a separate file? etc. I start with a vision of how the code should be but I keep facing walls and I need to mutate and rewrite and change the structure which is a huge waste of time and energy....

Can't retrieve data because of JsonIgnore
I'm using JsonIgnore to not include the data in the JSON file (the two properties where I'm using [JsonIgnore] are not allowed to be put inside the JSON file). The problem is that no matter what I've tried until now to retrieve the data in the overriden ToString() method, the datamodel that should contain the TimeTitlePair is always empty/null. I have never had C# up until this semester and this is one of the places where I struggle. I'll show the full code below:

Conveyor Placement System
I've been looking around but all I can find are solutions on how to move items on conveyors. However, my struggles are currently on how to make a placement system that works for me. Here is how it should work:
You select an input object (imagine it as a button). From there you can move your mouse to a dot in a grid where you want to place the first part of the conveyor.
As long as you left click somewhere, you add the current mouse position (snapped to a grid) as part of the conveyor and then you can set the next point.
When you select an output, it will add the output to the conveyor and stop.
Now, if you want to add a second output, you can click anywhere on the conveyor (again snapped to a grid) to "extend" the conveyor from there....

Trying to understand MVVM and MVC. Blazor ASP.NET
I'm trying to desgin a web portal using blazor but I can't really wrap my head around how I could code it. Mainly how exactly I could connect the database and the front end. Sorry if I'm asking too much.
How could I make use of design patterns like mvc and mvvm to help me out with this?
Is one strictly better or more modern or are they both useful and practical?
Do I have to pick between the two or is it possible to use both patterns at the same time? ...
