NetMQ: SendFrame never sends, never returns.

(I'm posting this here because I haven't found a ZeroMQ community. If you're aware of one, I'd appreciate a link.) (I have marked the question Beginner within the context of ZeroMQ; the problem really has little to do with C# or .Net.) I'm attempting to upgrade a .Net Framework 4.0 project to .Net Core. (The previous, working version of the project uses clrzmq.) So far I've managed to get it all working properly except the ZeroMQ aspect. ...

Choosing a model in ML.NET

I'm new to ML.NET (and ML in general) and I'm trying to learn a bit. My problem is the following: I have n iterations of a constant set of variables, and depending on the values of these variables I will get a score. The next iteration, n + 1, is dependent on the variables input in iteration n for it's score, and the variables of the current (n + 1) iteration. How would I choose an ML model to optimize the values of the variables each iteration in order to maximize the total score of all iterations?...

Spawning objects at random X co-ordinates and in fixed intervals

Hi, I am making a game inside Monogame, using c#. I need my objects in the game to spawn in random X co-ordinates. I know how to spawn more than one in a specific state, but I cannot figure out how to spawn them randomly. I've tried a few methods; having a random number generator decide which block to spawn, setting the x and y co-ordinates to random number, which both returned error messages. I'm hoping I can get some help with this? Thanks! I'll attach some screenshots when I have them.

WPF, window doesn't open with specified resolution

I have a button in my WPF project that opens a different window. Window should be 640x480 but when it opens by pressing the button it has the resolution of 800x600.
